This symbol indicates safety instructionswhere non-compliance will involve some risk to safeoperation and personal safety and would damage theequipment or property.

This symbol indicates explosive atmospherezone marking according to ATEX. It is used in safetyinstructions where non-compliance in the hazardousarea would cause the risk of an explosion.

This symbol is used in safety instructions toremind not to rub non-metallic surfaces with a drycloth; ensure cloth is damp. It is used where non-compliance in the hazardous area would cause the riskof an explosion.

This sign is not a safety symbol but indicatesan important instruction in the assembly process.

1.6.2 Personnel qualification and trainingAll personnel involved in the operation, installation,inspection and maintenance of the unit must bequalified to carry out the work involved. If thepersonnel in question do not already posse ss thenecessary knowledge and skil l, appropriate trainingand instruction must be provided. If required theoperator may commission the manufacturer/supplier toprovide applicable training.

Always coordinate repair activity with operations andhealth and safety personnel, and follow all plant safetyrequirements and applicable safety and health lawsand regulations.

1.6.3 Safety action

This is a summary of conditions and actions toprevent injury to personnel and damage to theenvironment and to equipment. For products usedin potentially explosive atmospheres section 1.6.4also applies.

NEVER DO MAINTENANCE WORKWHEN THE UNIT IS CONNECTED TO POWER

GUARDS MUST NOT BE REMOVED WHILETHE PUMP IS OPERATIONAL

DRAIN THE PUMP AND ISOLATE PIPEWORKBEFORE DISMANTLING THE PUMPThe appropriate safety precautions should be takenwhere the pumped liquids are hazardous.

FLUORO-ELASTOMERS (When fitted.)When a pump has experienced temperatures over 250ºC (482 ºF), partial decomposition of fluoro-elastomers(example: Viton) will occur. In this condition these areextremely dangerous and skin contact must beavoided.

HANDLING COMPONENTSMany precision parts have sharp corners and thewearing of appropriate safety gloves and equipment isrequired when handling these components. To liftheavy pieces above 25 kg (55 lb) use a craneappropriate for the mass and in accordance withcurrent local regulations.

THERMAL SHOCKRapid changes in the temperature of the liquid withinthe pump can cause thermal shock, which can result indamage or breakage of components and should beavoided.

NEVER APPLY HEAT TO REMOVE IMPELLERTrapped lubricant or vapour could cause an explosion.

HOT (and cold) PARTSIf hot or freezing components or auxil iary heatingsupplies can present a danger to operators andpersons entering the immediate area action must betaken to avoid accidental contact. If completeprotection is not possible, the machine access must belimited to maintenance staff only, with clear visualwarnings and indicators to those entering theimmediate area. Note: bearing housings must not beinsulated and drive motors and bearings may be hot.

If the temperature is greater than 68 °C (175 °F) orbelow 5 °C (20 °F) in a restricted zone, or exceedslocal regulations, action as above shall be taken.

HAZARDOUS LIQUIDSWhen the pump ishandling hazardousliquids care mustbe taken to avoid exposure to the liquid by appropriatesitting of the pump, limiting personnel access and byoperator training. If the liquid is flammable and/orexplosive, strict safety proceduresmust be applied.

Gland packing must not be used when pumpinghazardous liquids.

PREVENT EXCESSIVE EXTERNALPIPE LOADDo not use pump as a support for piping. Do not mountexpansion joints, unless allowed by Flowserve inwriting, so that their force, due to internal pressure,acts on the pump flange.

ENSURE CORRECT LUBRICATION(See section 5, Commissioning, startup, operation andshutdown.)

START THE PUMP WITH OUTLETVALVE PART OPENED(Unless otherwise instructed at a specific point in theUser Instructions.)

This is recommended to minimize the risk ofoverloading and damaging the pump motor at full orzero flow. Pumps may be started with the valve furtheropen only on installations where this situation cannotoccur. Pump outlet valve shall may need to beadjusted to comply with the duty following the run-upprocess. (See section 5, Commissioning start-up,operation and shutdown.)

NEVER RUN THE PUMP DRY

INLET VALVES TO BE FULLY OPENWHEN PUMP IS RUNNINGRunning the pump at zero flow or below therecommended minimum flow continuously will causedamage to the seal.

DO NOT RUN THE PUMP ATABNORMALLY HIGH OR LOW FLOW RATESOperating at a flow rate higher than normal or at a flowrate with no backpressure on the pump may overloadthe motor and cause cavitations. Low flow rates maycause a reduction in pump/bearing life, overheating ofthe pump, instability and cavitations/vibration.

1.6.4 Products used in potentially explosiveatmospheres

Measures are required to: Avoid excess temperature. Prevent build up of explosive mixtures. Prevent the generation of sparks. Prevent leakages. Maintain the pump to avoid hazard.

The following instructions for pumpsand pump unitswhen installed in potentially explosive atmospheresmust be followed to help ensure explosion protection.Both electrical and non-electrical equipment must meetthe requirements of European Directive 94/9/EC.

1.6.4.1 Scope of compliance

Use equipment only in the zone for which it isappropriate. Always check that the driver, drive couplingassembly, seal and pump equipmentare suitably ratedand/or certified for the classification of the specificatmosphere in which they are to be installed.

Where Flowserve has supplied only the bare shaftpump, the Ex rating applies only to the pump. The partyresponsible for assembling the pump set shall select thecoupling, driver and any additional equipment, with thenecessary CE Declaration of Conformity establishing itis suitable for the area in which it is to be installed.

The output from a variable frequency drive (VFD) cancause additional heating affects in the motor and so, forpumps sets with a VFD, the ATEX Certification for themotor must state that it is covers the situation whereelectrical supply is from the VFD. This particularrequirement still applies even if the VFDis in a safe area.

1.6.4.3 Avoiding excessive surface temperatures

ENSURE THE EQUIPMENT TEMPERATURECLASS IS SUITABLE FOR THE HAZARD ZONE

Pumps have a temperature class a s stated in theATEX Ex rating on the nameplate. These are based ona maximum ambient of 40 °C (104 °F); refer toFlowserve for higher ambient temperatures.

The surface temperature on the pump is influenced bythe temperature of the liquid handled. The maximumpermissible liquid temperature depends on thetemperature class and must not exceed the values inthe table that follows.

The temperature rise at the seals, bearings and due tothe minimum permitted flow rate is taken into accountin the temperatures stated.

The responsibility for compliance with the specifiedmaximum liquid temperature is with the plantoperator.

Temperature classification “Tx” is used when the liquid temperature varies and the pump could be installed indifferent hazardous atmospheres. In this case the useris responsible for ensuring that the pump surfacetemperature does not exceed that permitted in theparticular hazardous atmosphere.

If an explosive atmosphere exists during theinstallation, do not attempt to check the direction ofrotation by starting the pump unfilled. Even a short runtime may give a high temperature resulting fromcontact between rotating and stationary components.

Where there is any risk of the pump being run against aclosed valve generating high liquid and casing externalsurface temperaturesit is recommended that users fitan external surface temperature protection device.

Avoid mechanical, hydraulic or electrical overload byusing motor overload trips, temperature monitor or apower monitor and make routine vibration monitoringchecks.

In dirty or dusty environments, regular checks must bemade and dirt removed from areas around closeclearances, bearing housings and motors.

1.6.4.4 Preventing the build up of explosivemixtures

ENSURE PUMP IS PROPERLY FILLED ANDVENTED AND DOES NOT RUN DRY.

Ensure pump and relevant suction and dischargepipeline system is totally fi lled with liquid at all timesduring the pump operation, so that an explosiveatmosphere is prevented. In addition it is essential tomake sure that seal chambers, auxiliary shaft sealsystems and any heating and cooling systems areproperly filled.

If the operation of the system cannot avoid thiscondition the fitting of an appropriate dry run protectiondevice is recommended (eg liquid detection or powermonitor).

To avoid potential hazards from fugitive emissions ofvapour or gas to atmosphere the surrounding areamust be well ventilated.

1.6.4.5 Preventing sparks

To prevent a potential hazard from mechanicalcontact, the coupling guard must be non-sparking.To avoid the potential hazard from random inducedcurrent generating a spark the ground contact on thebaseplate must be used.

Avoid electrostatic charge: do not rub non-metallic surfaces with a dry cloth, ensure cloth isdamp.The coupling must be selected to comply with 94/9/ECand correct alignment must be maintained.

Additional requirements for metallic pumps onnon-metallic baseplatesWhen metall ic components are fitted on a non-metallicbaseplate they must be individually earthed.

1.6.4.6 Preventing leakage

The pump must only be used to handle liquidsfor which it has been approved to have the correctcorrosion resistance.

Avoid entrapment of liquid in the pump and associatedpiping due to closing of suction and discharge valves,which could cause dangerousexcessive pressures tooccur if there isheat input to the liquid.This can occur ifthe pump is stationary or running.

Bursting of liquid containing parts due to freezing mustbe avoided by draining or protecting the pump andancillary systems.

Where there is the potential hazard of a loss of a sealbarrier fluid or external flush, the fluid must bemonitored.

If leakage of liquid to atmosphere can result in ahazard, the installation of a liquid detection device isrecommended.

1.6.4.7 Maintenance to avoid the hazard

CORRECT MAINTENANCE IS REQUIRED TOAVOID POTENTIAL HAZARDS WHICH GIVE A RISKOF EXPLOSION

The responsibility for compliance with maintenanceinstructions is with the plant operator.

To avoid potential explosion hazards duringmaintenance, the tools, cleaning and paintingmaterials used must not give rise to sparking oradversely affect the ambient conditions.

Where there is a risk from such tools or materials;maintenance must be conducted in a safe area. It isrecommended that a maintenance plan and scheduleis adopted. (See section 6, Maintenance.)

1.9 Noise levelWhen pump noise level exceeds 85dBA attention mustbe given to prevailing Health and Safety Legislation, tolimit the exposure of plant operating personnel to thenoise. The usual approach is to control exposure timeto the noise or to enclose the machine to reduceemitted sound. You may have already specified alimiting noise level when the equipment was ordered,however if no noise requirements were defined thenmachines above a certain power level will exceed 85dB(A). In such situations consideration must be givento the fitting of an acoustic enclosure to meet localregulations.

Pump noise level is dependent on a number of factors- the type of motor fitted, the operating capacity,pipework design and acoustic characteristics of thebuilding. Typical sound pressure levels measured indB and A-weighted are shown in the table below.

The figures are indicative only, they are subject to a +3dB tolerance, and cannot be guaranteed.

The values are based on the noisiest ungeared electricmotors which are likely to be encountered. They areLpA sound pressure levels at 1m (3.3ft) from thedirectly driven pump, for "free field over a reflectingplane". For estimating LwA sound power level (re 1 pW)add 14 dB(A) to the sound pressure value.

If a pump only has been purchased, for fitting with yourown driver, then the "pump only" noise levels from thetable should be combined with the level for the driverobtained from the supplier. If the motor is driven by aninverter, it may show an increase in noise level atsome speeds. Consult a Noise Specialist for thiscalculation

For units driven by equipment other thanelectric motors or units contained within enclosures,see the accompanying information sheets andmanuals.

In areas where the staff has to intervene, rememberthat when the level of the sound pressure is:

Below 70 dBA :It is not necessary to takespecial precautions.

Above 70 dBA :People working continuously inthe machine room must besupplied with protective devicesagainst noise.

Below 85 dBA :No particular measures need to betaken for casual visitors staying inthe room during a limited period.

Above 85 dBA :The room must be considered as adangerous area because of thenoise and a warning sign must befixed at each entry warning thepeople coming into the room, evenfor a short period, that they mustwear hearing protection.

Above 105 dBA:Special hearing protection adaptedto this noise level and to thespectral noise components mustbe installed and a warning sign tothis effect erected at each entry.The staff in the room must wearear protection.

Make sure that the noise, which travels through thewalls and windows, does not generate too high noiselevels in the machine room's surroundings.

2 TRANSPORT AND STORAGE

2.1 Consignment receipt and unpackingImmediately after receipt of the equipment it must bechecked against the delivery and shipping documentsfor its completeness and that there has been nodamage in transportation.

Any shortage and or damage must be reportedimmediately to Flowserve Pump Division andreceived in writing within one month of receipt of theequipment. Later claims cannot be accepted.

Check any crate, boxes and wrappings for anyaccessories or spare parts that may be packedseparately with the equipment or attached to sidewalls of the box or equipment.

Each product has a unique serial number. Check thatthis number corresponds with that advised andalways quote this number in correspondence as wellas when ordering spare parts or further accessories.

2.2 Handling

2.2.1 General instructions concerning handlingBoxes, crates, pallets or cartons may be unloadedusing fork-lift vehicles or slings dependent on theirsize and construction. See 2.3.1 for positioning ofslings.

To lift heavy pieces above 55 lb (25 kg), use a cranecorresponding to the mass and in accordance withthe current local regulations.

To lift machines or pieces with one or several liftingrings, only use hooks and chains in compliance withthe local regulations concerning safety. Never putcables, chains or ropes directly on or in the liftingrings. Cables, chains or lifting ropes must neverpresent excessive bending.

Never bend the lifting hooks, lifting rings, chains,etc...They are only made to endure stresse s withincalculated limits. Remember that the capacity of alifting device decreases when the direction of thelifting force direction makes an angle with the deviceaxis.

To increase the safety and efficiency of the liftingdevice, all the lifting elements must be asperpendicular as possible. If necessary a lifting beamcan be placed between the crane and the load.

When heavy pieces are lifted up, never stay or workunder the load or in the area which could be in thepath of the load if it were to swing or fall away. Neverleave a load hanging from a crane. The accelerationor the deceleration of lifting equipment must stay inthe safety limits for the staff.

A crane must be positioned in such a way that theload will be raised perpendicularly. Where possiblenecessary precautions must be taken to avoid theswing of the load. For example use two winchesmaking approximately the same angle, less than 30°,with the vertical.

4 INSTALLATION

Equipment operated in hazardous locationsmust comply with the relevant explosion protectionregulations. See section 1.6.4, Products used inpotentially explosive atmospheres.

All equipment must be grounded.

4.1 LocationThe pump should be located to allow room foraccess, ventilation, maintenance and inspection withample headroom for lifting and should be as close aspracticable to the supply of liquid to be pumped.

The pump should be located above the flood level.The pipework should be such that there is anadequate NPSH at the pump centreline.Thefoundation should provide enough support so that thepump is not supported by the pipework.

Refer to the general arrangement drawing for thepump set.

4.2 Cleaning prior to installationRemove glue and dirt from suction and dischargeflanges. Check motors to make sure no foreignobjects have entered through fan and coolingopenings. Remove any compounds on exposedareas of pump shaft. Clean pump and motornameplate.

4.3 Foundation

There are many methods of installingpump units to their foundations. The correct methoddepends on the size of the pump unit, its location andnoise vibration limitations. Non-compliance with theprovision of correct foundation and installation maylead to failure of the pump and, as such, would beoutside the terms of the warranty.

4.3.1 General recommendationsFoundation bolts should be located or embedded inthe concrete by lay-out or template in relation to thesuction and discharge piping. Foundation bolts of thespecified size may be enclosed in a pipe sleeve twoor three diameters larger than the bolts tocompensate for minor variation in alignment.

Standard accessory steel baseplates furnished withthese pumps and motors 10 HP (7.5 kW) and undermay be bolted to machine or equipment structures,either rigidly or, if flexible piping is used, with properlydesigned vibration isolators.

A unit mounted on steel work or structural membersshould be mounted over or adjacent to girders orwalls so that no misalignment will occur from yieldingor sagging of the structure.

Anchor bolts must be in accordance with the foot boltholes. Use anchor bolts of accepted standards andsufficient to ensure seave fitting in the foundation.Particularly, this applies to individual plates where theanchor bolts have to withstand the driving torque.Provide sufficient space in the foundation toaccommodate the anchor bolts. If necessary, provideconcrete risers.

4.3.2 Positioning on foundationPumps are generally shipped mounted, and it isusually unnecessary with units of moderate size toremove the pump or driver from its baseplate whenlevelling.

Ensure the following are met:a) Clean the foundation thoroughly.b) The baseplate should be mounted onto a firm

foundation, either an appropriate thickness ofquality concrete or sturdy steel frameworkcapable of absorbing all normal vibrations. (Itshould NOT be distorted or pulled down onto thesurface of the foundation, but should besupported to maintain the original alignment).

c) Install the baseplate onto packing pieces evenlyspaced and adjacent to foundation bolts.

d) Level with shims, about 25 mm (1”), between baseplate and packing pieces.

e) Check the horizontal position by means of aprecision level placed upon an adequatereference (discharge flange, machined surfacesof casings etc...). Tolerances within 0.5 mm perm (0.006 in per ft).

f) The pump and driver have been aligned beforedispatch however the alignment of pump and motorhalf coupling must be checked. If this is incorrect, itindicates that the baseplate has become twistedand should be corrected by re-shimming.

barriers

g) If anchor bolts have been embedded in thefoundation, slightly tighten the anchor bolts.Otherwise let them hang in the foundation holes.

h) If not supplied, guarding shall be fitted as necessaryto meet the requirementsof EN292 and EN953 andor any applicable local safety regulations.

4.4 Grouting

Where applicable, grout in the foundation bolts.

Grouting provides solid contact between the pumpunit and foundation prevents lateral movement ofrunning equipment and dampens resonant vibrations.

Prepare the site for grouting. Before grouting cleanthe foundation surface thoroughly. Provide externalbarriers as shown:

Prepare grouting product (concrete, resin) inaccordance with manufacturers' instructions.(Use anti-shrink products)To grout up to the required level. Polish surfaces.Take necessary precautions to avoid air bubbles.Lay-down the barrier, break external angles andpolish the different surfaces.

Foundation bolts should only be fully tightened whenthe grout has cured.

4.5 Initial alignment

Before connecting the couplings verifythe motor rotation direction.

4.5.1 Thermal expansion

The pump and motor will normallyhave to be aligned at ambient temperature andshould be corrected to allow for thermal expansion atoperating temperature. In pump installations involvinghigh liquid temperatures, the unit should be run at theactual operating temperature, shut down and thealignment checked immediately.

4.5.2 Alignment methods

Ensure pump and driver are isolatedelectrically and the half couplings are disconnected.Ensure that the pump pipework, suction anddischarge, is disconnected.

The alignment MUST be checked.

Although the pump will have been aligned at thefactory it is most likely that this alignment will havebeen disturbed during transportation or handling. Ifnecessary, align the motor to the pump, not the pumpto the motor.

Pump-Driver unit supplied assembled on theirbaseplate:The machines have originally been aligned in thework-shop.

Pump and Driver supplied on separate baseplates:The machines have originally been mounted on theirrespective baseplate in the workshop. The pump is tobe installed first and should be considered as thefixed point. The alignment is then performed on thedriver alone.

Before aligning verify that the pump is horizontal byusing a flange surface or other horizontal surface.Adjust if necessary by adjusting the height of thewobble foot. Tighten any nuts that have beenloosened.

Alignment is achieved by adding or removing shimsunder the motor feet and also moving the motorhorizontally as required. In some cases where thealignment cannot be achieved it will be necessary tomove the pump before recommencing the aboveprocedure.

For couplings with narrow flanges use a dial indicatoras shown below to check both parallel and angularalignment.


of 46

®

Paral lel

Angular

Maximum permissible misalignment at workingtemperature:

Parallel 0.2 mm (0.008 in.) TIRAngular 0.1 mm (0.004 in.) TIR

When checking parallel alignment, the total indicatorread-out (TIR) shown is twice the value of the actualshaft displacement.

Align in the vertical plane first, then horizontally bymoving motor. When performing final alignment, checkfor soft-foot under the driver. A TIR indicator placed onthe coupling, reading in the vertical direction, should notindicate more than 0.05 mm (0.002 in.) movement whenanydriver foot fastener is loosened.

While the pump is capable of operating with themaximum misalignment shown above, maximum pumpreliability is obtained by near perfect alignment of 0.05to 0.10 mm (0.002 to 0.004 in.) TIR parallel and0.05 mm (0.002 in.) per 100 mm (4 in.) of couplingflange diameter asTIR angular misalignment. Thiscovers the full series of couplings available.

Pumps with thick flanged non-spacer couplings canbe aligned by using a straight-edge across theoutside diameters of the coupling hubs andmeasuring the gap between the machined facesusing feeler gauges, measuring wedge or calipers.

When the electric motor has sleeve bearings it isnecessary to ensure that the motor is aligned to runon its magnetic centreline.

Refer to the motor manual for details.

A button (screwed into one of the shaft ends) isnormally fitted between the motor and pump shaftends to fix the axial position.

If the motor does not run in itsmagnetic centre the resultant additional axial forcemay overload the pump thrust bearing.

Complete piping as below and see sections 4.7,Final shaft alignment check up to and includingsection 5, Commissioning, startup, operation andshutdown before connecting driver and checkingactual rotation.

4.6 Piping

The user must verify that the equipment isisolated from any external sources of vibration.

Protective covers are fitted to the pipeconnections to prevent foreign bodies entering duringtransportation and installation. Ensure that thesecovers are removed from the pump before connectingany pipes.

4.6.1 Suction and discharge pipeworkIn order to minimize friction losses and hydraulicnoise in the pipework it is good practice to choosepipework that is one or two sizes larger than thepump suction and discharge. Typically main pipeworkvelocities should not exceed 2 m/s (6 ft/sec) suctionand 3 m/s (9 ft/sec) on the discharge.

Take into account the available NPSH must be higherthan the required NPSH of the pump. Whendetermining the NPSH available the vapour pressureat the operating temperature must be taken intoaccount.

Never use the pump as a support forpiping.

Maximum forces and moments allowed on the pumpflanges vary with the pump size and type. Tominimize these forces and moments that may, ifexcessive, cause misalignment, hot bearings, worncouplings, vibration and the possible failure of thepump casing, the following points should be strictlyfollowed: Prevent excessive external pipe load Never draw piping into place by applying force to

pump flange connections. Do not mount expansion joints so that their force,

due to internal pressure, acts on the pump flange.It is recommended that expansion joints usethreaded rod to limit any forces of this type.

Thermal expansions must be compensated insuch a way that no additional forces act on thepump flanges.

Make sure that piping flanges are square andconcentric to the pump flanges.


of 46

®

The table in 4.6.3 summarizes the maximum forcesand moments allowed on WDX pump casings. Referto Flowserve for other configurations.

Ensure piping and fittings are flushedbefore use.

Ensure piping for hazardous liquids is arrangedto allow pump flushing before removal of the pump.

Excessive external strains (forces, moments)may cause misalignment, general vibrations, hotbearings or excessive wear on couplings and seals.In extreme cases, leakage may result with potentialloss of life with hot or corrosive liquids.

4.6.2 Suction pipingRefer to the diagrams below for typical designs ofsuction piping for both flooded suction and suction lift.a) The inlet pipe should be one or two sizes larger

than the pump inlet bore and pipe bends shouldbe as large a radius as possible.

b) Pipework reducers should be conical and have amaximum total angle of divergence of 15 degrees.

c) Pipework should be arranged to avoid air pockets.d) If high points cannot be avoided on the suction line

equip them with air relief cocks.e) On suction lift the piping should be inclined up

towards the pump inlet with eccentric reducersincorporated to prevent air locks.

f) On positive suction, the inlet piping must have aconstant fall towards the pump.

g) Flow should enter the pump suction with uniformflow, to minimize noise and wear. This isparticularly important on large or high-speedpumps which should have a minimum of fivediameters of straight pipe on the pump suctionbetween the elbow and inlet flange. See section10.3, Reference 1, for more detail.

h) Inlet strainers, when used, should have a net `freearea' of at least three times the inlet pipe area.

i) Do not install elbows at an angle other thanperpendicular to the shaft axis. Elbows parallel tothe shaft axis will cause uneven flow.

j) Except in unusual circumstances strainers arenot recommended in inlet piping. If considerableforeign matter is expected a screen installed atthe entrance to the wet well is preferable.

k) Fitting an isolation valve will allow easiermaintenance.

l) If an inlet valve is necessary, choose a modelwith full bore so as to limit losse s. Valve stemshould be in a vertical position. There should bea minimum of five pipe diameters between thepump and the valve.

m) Never throttle pump on suction side and neverplace a valve directly on the pump inlet nozzle.

n) Do not tighten flanges before the final check.

Typical design –flooded suction

Note:Ideally reducers should be limited to one pipe diameter change,ie 150 mm (6 in.) to 200 mm (8 in.). Must have a maxi mum totalangle of di vergence of 15 degrees.

Typical design –suction lift

Notes:1. S = Minimum submergence >3E.2. Ideally r educers to be limited to one pipe di ameter change,

4.6.4 Discharge pipingSee section 4.6.2 for typical pipework design.

A non-return valve should be located in the dischargepipework to protect the pump from excessive backpressure and hence reverse rotation when the unit isstopped.

Pipework reducers should have a maximum totalangle of divergence of 9 degrees.

Fitting an isolation valve will alloweasier maintenance.It should be installed downstream of the non-returnvalve.

If needed a control pressure gauge may be installedon the pipework.

Do not tighten the pipe flanges before the final check.

4.6.5 Auxiliary piping

4.6.5.1 DrainsPipe pump casing drains and gland leakage to aconvenient disposal point.

4.6.5.2 Pumps fitted with mechanical sealsSingle seals requiring re-circulation will normally beprovided with the auxiliary piping from pump casingalready fitted.

If the seal requires an auxiliary quench then aconnection must be made to a suitable source ofliquid flow, low pressure steam or static pressure froma header tank. Recommended pressure is 0.35 bar (5psi) or less. Check General arrangement drawing.

Special seals may require different auxiliary piping tothat described above. Consult separate UserInstructions and or Flowserve if unsure of correctmethod or arrangement.For pumping hot liquids, to avoid seal damage, it isrecommended that any external flush/cooling supplybe continued after stopping the pump.

4.6.6 Final checksCheck the tightness of all bolts in the suction anddischarge pipework. Tighten if necessary. Check alsothe tightness of all foundation bolts. Tighten ifnecessary. Check the tightness of all auxiliary piping.Tighten if necessary.

4.7 Final shaft alignment checkAfter connecting piping to the pump, rotate the shaftseveral times by hand to ensure there is no bindingand all parts are free.

Recheck the coupling alignment, as previouslydescribed, to ensure no pipe strain. If pipe strainexists, correct piping.

Alignment can only be considered definitive afterpipework has been connected.

4.8 Electrical connections

4.8.1 Safety conditions about electricalconnections

Electrical connections must be madeby a qualified Electrician in accordance with relevantlocal national and international regulations. Thisincludes any grounding.

It is important to be aware of the EUROPEANDIRECTIVE on potentially explosive areas wherecompliance with IEC60079-14 is an additionalrequirement for making electrical connections.

Avoid mechanical, hydraulic or electricaloverload by using motor overload trips or a powermonitor and make routine vibration monitoring.

It is important to be aware of the EUROPEANDIRECTIVEon electromagnetic compatibility whenwiring up and install ing equipment on site.Attentionmust be paid to ensure that the techniquesused duringwiring/installation do not increase electromagneticemissions or decrease the electromagnetic immunity ofthe equipment, wiring or any connected devices. If inanydoubt, contact Flowserve for advice.

The motor must be wired up inaccordance with the motor manufacturer'sinstructions (normally supplied within the terminalbox) including any temperature, earth leakage,current and other protective devices as appropriate.The identification nameplate should be checked toensure the power supply is appropriate.

A device to provide emergency stopping mustbe fitted.

If not supplied pre-wired to the pump unit, thecontroller/starter electrical details will also be suppliedwithin the controller/starter.

For electrical details on pump sets with controllerssee the separate wiring diagram.

See section 5.3, Direction of rotationbefore connecting the motor to the electrical supply.

4.9 Protection systems

The following protection systems arerecommended particularly if the pump is installed in apotentially explosive area or is handling a hazardousliquid. If in doubt consult Flowserve.

If there is any possibility of the system allowing thepump to run against a closed valve or belowminimum continuous safe flow a protection deviceshould be installed to ensure the temperature of theliquid does not rise to an unsafe level.

If there are any circumstances in which the systemcan allow the pump to run dry, or start up empty, apower monitor should be fitted to stop the pump orprevent it from being started. This is particularlyrelevant if the pump is handling a flammable liquid.

If leakage of product from the pump or its associatedsealing system can cause a hazard it isrecommended that an appropriate leakage detectionsystem is installed.

To prevent excessive surface temperatures atbearings it is recommended that temperature orvibration monitoring are carried out. See sections5.7.4 and 5.7.5.

If a defect of cooling can lead to temperature higherthan those acceptable a system of coolingsurveillance must be installed.

Except when explicitly required by the customer inthe specifications, when a possibility of reverserotation exists the customer must install a reverserotation protection device.

The customer must install all equipment required toavoid water hammer.

5 COMMISSIONING, START-UP,OPERATION AND SHUTDOWN

These operations must be carried out byfully qualified personnel.

5.1 Pre-commissioning procedure

5.1.1 LubricationDetermine the mode of lubrication of the pump set,eg grease, oil, product lubrication etc.

Grease lubricated pumps and electric motors aresupplied pre-greased.

Other drivers and gearboxes, if appropriate, shouldbe lubricated in accordance with their manuals.

In the case of product lubricatedbearings the source of product supply should bechecked against the order. There may berequirements for an external clean supply, particularsupply pressure or the commencement of lubricationsupply before pump start-up.

5.1.2 Oil LubricationThe bearings are lubricated by pins. A constant leveloiler automatically maintains the correct oil level.

The oiler supplies the necessary quantity of oil. Itoperates on the liquid seal principal and feeds with oilonly when the quantity of oil becomes too low in thebearing. It will stop to feed once a sufficient quantityof oil is in the bearing.

The reserve contained in the reservoir refil lsautomatically the natural losse s of the bearing. Assoon as the oil level approaches the minimum level ofthe reservoir, refill the reservoir.

Regarding the quality and the quantity of the oil to beused, refer to the lubrication table and informationbelow.

For oil lubricated pumps, fill the bearinghousing with correct grade of oil to the correct level, iesight glass or constant level oiler bottle.

See below for the correct side on which constantlevel oilers should be installed.

5.2.4 Lubrication schedule

5.2.4.1 Oil lubricated bearingsOperating conditions and severity of service willdetermine the intervals between oil changes. Ingeneral higher oil temperatures will require morefrequent oil changes.

For pumps on hot service or in severely damp orcorrosive atmosphere, the oil will require changingmore frequently. If the bearings maintain a stabletemperature and if there has been no contaminationof the oil, the interval between changes may belonger.

Lubricant and bearing temperature analysis can beuseful in optimising lubricant change intervals.Generally, the oil should be changed every 6 months.If the bearing temperature increases, checkimmediately for improper lubrication or a faultybearing.

The lubricating oil should be a high quality mineral oilhaving foam inhibitors. Synthetic oils may also be usedif checks show that the rubber oil seals will not beadversely affected.

The bearing temperature may be allowed to rise to 50ºC (122 ºF).above ambient, but should not exceed 82ºC (180 ºF). A continuously rising temperature or anabrupt rise, indicate a fault.

5.2.4.2 Grease lubricated bearingsThe bearings are prelubricated when supplied.Lubrication frequency is as indicated in the tablebelow. After a 2 years period the bearing should becompletely cleaned, checked and repacked with newgrease.

The free bearing space should not be filled up morethat 50 % to 60 % of its content see 5.2.3. Care mustbe taken to avoid both under and over-lubrication.

Over lubrication will cause the bearings to run hotterthan normal, while under-lubricated bearings couldwear prematurely.

The characteristics of the installation and severity ofservice will determine the frequency of lubrication.Lubricant and bearing temperature analysis can beuseful in optimising lubricant change intervals.

Never mix greases containing differentbases, thickeners or additives.

5.3 Direction of rotation

Starting or operating pumps with thewrong direction of rotation can be harmful to thepumps.

Ensure that the pump rotation is the same as thearrow on the pump casing.It is preferable to check the direction of rotationbefore installing the coupling. If not, the pump mustbe filled in with the liquid before start-up.

If maintenance work has been carriedout to the site's electricity supply, the direction ofrotation should be re-checked as above in case thesupply phasing has been altered.

5.4 Guarding

Guarding is supplied fitted to the pump set.If this has been removed or disturbed ensure that allthe protective guards around the pump coupling andexposed parts of the shaft are securely fixed.

5.5 Priming and auxiliary supplies

Where there is any risk of the pump being runagainst a closed valve generating high liquid andcasing external surface temperatures it isrecommended that users fit an external surfacetemperature protection device.

Ensure all electrical, hydraulic,pneumatic, sealant and lubrication systems (asapplicable) are connected and operational.

Ensure the inlet pipe and pump casingare completely full of liquid before starting continuousduty operation.

These operations must be carried out by personnelwith approved qualifications.

5.5.1 Suction pressure above atmosphericpressureOpen the air vent connection to allow the trapped airto escape. Let liquid run out until free from airbubbles.

5.5.2 Suction lift with foot v alve fittedFill suction pipe and casing with liquid at a pressureof 1 to 2 bar from an external source. Vent asdescribed in section 5.5.1.

Foot valves are not recommended whenthe pumped liquid has suspended solid particles.They may lodge between foot valve seat and shutter.

5.5.3 Suction lift without foot v alvePump casing vents on the suction volute must beconnected to an external vacuum pump primingsystem. If in doubt, please consult Flowserve.

5.6 Starting the pump

a) Ensure flushing and/or cooling/heating liquid supplies are turned ON beforestarting the pump.

b) CLOSE the outlet valve. If the pump is equippedwith a non-return flow valve and is to be startedwith an opened discharge valve, verify that it isclosed by an adequate back pressure.

c) OPEN all inlet valves.d) Open all valves of the minimal flow line to ensure

a minimal flow for the period the pump is runningagainst the closed discharge valve.

e) Prime the pump.f) Check that all plugs are tight.g) Check that the gland lightly tightens the packing.

h) Ensure all vent connections are closedbefore starting.

i) Start motor and check outlet pressure.j) If the pressure is satisfactory, slowly OPEN outlet

control valve.

k) Do not run the pump with theoutlet valve closed for a period longer than 20seconds.

l) If NO pressure, or LOW pressure, STOP thepump. Refer to section 7, Faults; causes andremedies, for fault diagnosis.

5.7 Running the pump

5.7.1 Venting the pump

Vent the pump to enable all trapped air toescape taking due care with hot or hazardous liquids.

Under normal operating conditions, after the pumphas been fully primed and vented, it should beunnecessary to re-vent the pump.

5.7.2 Pumps fitted with packed gland

If the pump has a packed gland there must be someleakage from the gland. Gland nuts should initially befinger-tight only. Leakage should take place soonafter the stuffing box is pressurized.


of 46

®

The gland must be adjusted evenly to givevisible leakage and concentric alignment of the glandring [4120] to avoid excess temperature. If noleakage takes place the packing will begin tooverheat. If overheating takes place the pump shouldbe stopped and allowed to cool before being re-started. When the pump is re-started, check toensure leakage is taking place at the packed gland.

If hot liquids are being pumped it may be necessaryto slacken the gland nuts to achieve leakage.

The pump should be run for ten minutes with steadyleakage and the gland nuts tightened by 10 degreesat a time until leakage is reduced to an acceptablelevel. The temperature of the gland should bechecked after each round of tightening. If thetemperature starts to climb rapidly then back off thegland nuts until the temperature drops down. Wait forthe temperature to stabilize before tightening again.The leakage must not be reduced below a rate of 20drops per minute. Bedding in of the packing may takeseveral hours.

Care must be taken when adjusting the glandon an operating pump. Safety gloves are essential.Loose clothing must not be worn to avoid beingcaught up by the pump shaft. Shaft guards must bereplaced after the gland adjustment is complete.

Never run gland packing dry, even fora short time.

5.7.3 Pumps fitted with mechanical sealMechanical seals require no adjustment. Any slightinitial leakage will stop when the seal is run in.

Before pumping dirty liquids it is advisable, ifpossible, to run in the pump mechanical seal usingclean liquid to safeguard the seal face.

External flush or quench should bestarted before the pump is run and allowed to flow fora period after the pump has stopped.

Never run a mechanical seal dry, evenfor a short time.

5.7.4 Bearings

If the pumps are working in a potentiallyexplosive atmosphere, temperature or vibrationmonitoring at the bearings is recommended.

If bearing temperatures are to be monitored it isessential that a benchmark temperature is recordedat the commissioning stage and after the bearingtemperature has stabilized. Record the bearing temperature (t) and the

ambient temperature (ta) Estimate the likely maximum ambient

temperature (tb) Set the alarm at (t+tb-ta+5) C [(t+tb-ta+10) F]

and the trip at 100 C (212 F) for oil lubricationand 105 C (220 F) for grease lubrication

It is important, particularly with grease lubrication, tokeep a check on bearing temperatures. After start upthe temperature rise should be gradual, reaching amaximum after approximately 1.5 to 2 hours. Thistemperature rise should then remain constant ormarginally reduce with time. (Refer to section 6.2.3.1for further information.)

5.7.5 Normal v ibration levels, alarm and tripFor guidance, pumps generally fall under aclassification for rigid support machines within theInternational rotating machinery standards and therecommended maximum levels below are based onthose standards.

Alarm and trip values for installedpumps should be based on the actual measurements(N) taken on site on the bearing housings of thepump in the fully commissioned as new condition.

The example (N) value is given for the preferredoperating flow region (typically this may extend to 70to 120 % of the pump best efficiency point); outsidethe preferred flow region the actual vibrationexperienced may be multiplied by up to 2.

These standard values can vary with the rotationalspeed and the power absorbed by the pump. For anyspecial case, do not hesitate to consult us.

Measuring vibration at regular intervals will then showany deterioration in pump or system operatingconditions.

Where duty and standby pumps are installed it isrecommended that they are run alternately every week.

5.8 Stopping and shutdown

a) Close the outlet valve, but ensurethat the pump runs in this condition for no morethan a few seconds.

b) Stop the pump.c) Avoid having the unit turn in the opposite

direction of the normal running conditionsd) Protect the pump against water hammer.e) Make sure that the discharge line pressure does

not reach the foot valve.f) Switch off flushing and/or cooling/heating liquid

supplies at a time appropriate to the process.

g) For prolonged shut-downs andespecially when ambient temperatures are likelyto drop below freezing point, the pump and anycooling and flushing arrangements must bedrained or otherwise protected. When drainingthe pump, first verify that the liquid temperaturehas cooled sufficiently to allow safe maintenance.

5.9 Hydraulic, mechanical and electricaldutyThis product has been supplied to meet theperformance specifications of your purchase order,however it is understood that during the life of theproduct these may change.The following notes mayhelp the user decide how to evaluate the implicationsof any change. If in doubt contact your nearestFlowserve office.

5.9.1 Specific gravity (SG)Pump capacity and total head in meters (feet) do notchange with SG, however pressure displayed on apressure gauge is directly proportional to SG. Powerabsorbed is also directly proportional to SG. It istherefore important to check that any change in SGwill not overload the pump driver or over-pressurizethe pump.

5.9.2 ViscosityFor a given flow rate the total head reduces withincreased viscosity and increases with reducedviscosity. Also for a given flow rate the powerabsorbed increases with increased viscosity, andreduces with reduced viscosity.

It is important that checks are made with your nearestFlowserve office if changes in viscosity are planned.

5.9.3 Pump speedChanging pump speed effects flow, total head, powerabsorbed, NPSHR, noise and vibration. Flow varies indirect proportion to pump speed, head varies asspeed ratio squared and power varies as speed ratiocubed. The new duty, however, will also bedependent on the system curve. If increasing thespeed, it is important therefore to ensure themaximum pump working pressure is not exceeded,the driver is not overloaded, NPSHA > NPSHR, andthat noise and vibration are within local requirementsand regulations.

5.9.4 Net positiv e suction head (NPSHA)NPSH available (NPSHA) is the head available at theimpeller inlet, above the vapour pressure of thepumped liquid.

NPSH required (NPSHR) is the minimum head requiredat the impellerinlet, above the vapour pressure of thepumped liquid, to avoid excessive cavitation andextreme performance degradation.

It is important that NPSHA > NPSHR. The marginbetween NPSHA > NPSHR should be as large aspossible.

If any change in NPSHA is proposed, ensure thesemargins are not significantly eroded. Refer to thepump performance curve to determine exactrequirements particularly if flow has changed. If indoubt please consult your nearest Flowserve officefor advice and details of the minimum allowablemargin for your application.

5.9.5 Pumped flowFlow must not fall outside the minimum andmaximum continuous safe flow shown on the pumpperformance curve and or data sheet.

5.10 Pumps for Food Use or PotableWaterIf the pump has not been specifically ordered for afood or drinking water application it must not be usedfor these types of applications. If it has been orderedfor this type of application the followingrecommendations are to be followed.

5.10.1 Cleaning prior to operationPumps that are to be used for a food or drinkingwater application should be cleaned before being putinto initial operation and after the installation of spareparts that are in contact with the liquid.

®

Cleaning once the pump has been commissioned willdepend on the application and operating conditions.The user must ensure that the cleaning proceduresare suitable for the application and operatingconditions, and local regulations.

6 MAINTENANCE

6.1 General

If a belt drive is used, the assembly and tensionof the belts must be verified during regularmaintenance procedure.

In dirty or dusty environments, regular checksmust be made and dirt removed from areas aroundclose clearances, bearing housings and motors.

It is the plant operator's responsibility to ensurethat all maintenance, inspection and assembly workis carried out by authorized and qualified personnelwho have adequately familiarized themselves withthe subject matter by studying this manual in detail.(See also section 1.6.2.)

Any work on the machine must be performed when itis at a standstill. It is imperative that the procedure forshutting down the machine is followed, as describedin section 5.8.

On completion of work all guards and safety devicesmust be re-installed and made operative again.

Before restarting the machine, the relevantinstructions listed in section 5, Commissioning, startup, operation and shut down must be observed.

Oil and grease leaks may make the groundslippery. Machine maintenance must alwaysbegin and finish by cleaning the ground and theexterior of the machine.

If platforms, stairs and guard rails are required formaintenance, they must be placed for easy access toareas where maintenance and inspection are to becarried out. The positioning of these accessoriesmust not limit access or hinder the lifting of the part tobe serviced.

When air or compressed inert gas is used in themaintenance process, the operator and anyone in thevicinity must be careful and have the appropriateprotection.

Do not spray air or compressed inert gas on skin.

Do not direct an air or gas jet towards other people.

Never use air or compressed inert gas to cleanclothes.

Before working on the pump, take measures toprevent an uncontrolled start. Put a warning board onthe starting device with the words:"Machine under repair: do not start".With electric drive equipment, lock the main switchopen and withdraw any fuses. Put a warning boardon the fuse box or main switch with the words:"Machine under repair: do not connect".

Never clean equipment with inflammable solvents orcarbon tetrachloride. Protect yourself against toxicfumes when using cleaning agents.

6.2 Maintenance schedule

It is recommended that a maintenance plan andschedule is adopted, in line with these UserInstructions. It should include the following:a) The pump must be completely vented and

drained and rendered inert before anydisassembly operation.

b) Any auxiliary systems installed must bemonitored, if necessary, to ensure they functioncorrectly.

c) During cleaning of the pump ensure thecompatibility between the cleaning products andthe gaskets.

d) Verify the condition of the gasketse) Gland packings must be adjusted correctly to

give visible leakage and concentric alignment ofthe gland follower to prevent excessivetemperature of the packing or follower.Mechanical seals should present no leakage.

f) Check for any leaks from gaskets and seals. Thecorrect functioning of the shaft seal must bechecked regularly.

g) Check bearing lubricant level, and if the hoursrun show a lubricant change is required.

h) Check that the duty condition is in the safeoperating range for the pump.

i) Check vibration, noise level and surfacetemperature at the bearings to confirmsatisfactory operation.

j) Check the tightness of the connections.k) Checkdirt and dust is removed from areas around

close clearances, bearing housingsand motors.l) Check coupling alignment and re-align if necessary.m) Verify the correct operation of the system.

The equipment used for maintenance and disassemblyin an ATEX zone must be in conformity with therequirements zone.

Our specialist service personnel can help withpreventative maintenance records and providecondition monitoring for temperature and vibration toidentify the onset of potential problems.

If any problems are found the following sequence ofactions should take place:a) Refer to section 7, Faults; causes and remedies,

for fault diagnosis.b) Ensure equipment complies with the

recommendations in this manual.c) Contact Flowserve if the problem persists.

6.2.1 Routine inspection (daily/weekly)

The following checks should be madeand the appropriate action taken to remedy anydeviations:a) Check operating behaviour. Ensure noise,

vibration and bearing temperatures are normal.b) Check that there are no abnormal fluid or

lubricant leaks (static and dynamic seals) andthat any sealant systems (if fitted) are full andoperating normally.

c) Check that shaft seal leaks are within acceptablelimits.

d) Check the level and condition of oil lubricant.On grease lubricated pumps, check runninghours since last recharge of grease or completegrease change.

e) Check any auxiliary supplies eg heating/cooling,if fitted, are functioning correctly.

Refer to the manuals of any associatedequipment for routine checks needed.

6.2.2 Periodic inspection (six monthly)

a) Check foundation bolts forsecurity of attachment and corrosion.

b) Check pump running records for hourly usage todetermine if bearing lubricant requires changing.

c) The coupling should be checked for correctalignment and worn driving elements.

Refer to the manuals of any associatedequipment for periodic checks needed.

6.2.3 Re-lubricationLubricant and bearing temperature analysis can beuseful in optimising lubricant change intervals. Ingeneral however, the following is recommended.

6.2.3.1 Oil lubrication

Maintaining the correct oil level is veryimportant.

If the pump is supplied with a constant level oiler theoil level will be automatically maintained and as longas oil is visible in the glass bottle there is no need torefill . If however a sight glass has been fitted thenregular checks should be made to ensure the level ismaintained at the centre of the glass window.

Refer to section 5.1.1 for methods of oil fi ll , section5.2.1 for oil grade recommendations and 5.2.4 for theschedule and temperature limits.

6.2.3.2 Grease lubrication

See section 5.2.2 for greaserecommendations.

Regrease–refer to section 5.2.4.2.a) It is important not to under or over grease the

bearings as this will lead to over heating andpremature failure. Grease lubricated bearinghousings have grease nipples fitted in thebearing covers.

b) The used grease should be seen to evacuatethrough the bottom of the bearing housing.

c) The maximum allowable operating temperaturesfor anti friction bearings will vary from unit to unit,depending on ambient and fluid temperature. Therise above ambient should not normally exceed55 C (131 F) or a combined maximum of 95 C(204 F).

d) A continuously rising temperature or an abrupttemperature rise indicates a problem. If thesesymptoms occur, stop the pump immediately andinvestigate the cause.

c) Clean and flush out the housing with a lightmineral oil.

d) Do not use waste oil to clean the housing.

To clean the bearings:a) Wipe off as much grease as possible with a clean

lint-free cloth.b) Brush bearings with hot kerosene (80 to 90 °C/

175 to 195 °F) while gently spinning the outerbearing ring.

c) Spin each ball to ensure that it is clean.

To remove badly oxidized grease which refuses tocome off:Dry and reflush the bearing with clean light oil.

It is important not to under or over grease thebearings as this will lead to over heating andpremature failure. It is recommended that thebearings be filled with grease using a suitablespatula. In addition the housings should be no morethan half fil led.

6.2.4 Mechanical sealsThe current maintenance is limited to seal control. Itis necessary to detect any small leakage whichannounces the beginning of the deterioration offriction faces or secondary seal elements (rings,bellows, synthetic membranes). It is advisable to stopthe pump as soon as possible. Have an approvedseal vendor replace or repair the seal.

6.2.5 Gland packing

6.2.5.1 Pump fitted with a packed glandA well run in and correctly adjusted packing glandrequires little maintenance.If, after some time, the leakage becomes too great,the gland should be tightened again in order to returnthese to a normal level.If re-tightening is not possible, new packing must beinstalled.

6.2.5.2 Gland packing inspection and removala) Remove the shield guardsb) Slide back the glandc) Remove the packing rings with an extractordesigned for this purpose (including the lantern ring ifit exists; note its position and its direction of rotation).d) Inspect the state of the sleeve surface; thepresence of many marked grooves will indicate that itmust be replaced.e) Carefully clean the different pieces of the packinggland.

6.2.5.3 Gland packing fittingIf the packing is supplied as cord the packing must becut so that the external diameter is lightly tightenedand there is an initial gap between the sleeve and thepacking ring.

For that purpose, wind the packing helically aroundthe shaft sleeve or a chuck of the same diameter.(Take precautions to avoid damaging sleeve).

Example of straight cut E xample of bevel cut

Ensure a tightening on the stuffing boxhousing and not on the sleeve.

6.2.6 Gland coolingWDX Pumps are designed with an optional stuffingbox cooling. The purpose of this is to cool thepumped liquid before it reaches the packing. Suchcooling is required if the liquid temperature is over220° F (105°C).

6.3 Spare parts

6.3.1 Ordering of sparesFlowserve keeps records of all pumps that have beensupplied. When ordering spares the followinginformation should be quoted:

1) Pump serial number.2) Pump size.3) Part name–taken from assembly drawing.4) Part number–taken from assembly

drawing.5) Number of parts required.

The pump size and serial number are shown on thepump nameplate.

To ensure continued satisfactory operation,replacement parts to the original design specificationshould be obtained from Flowserve.

Any change to the original design specification(modification or use of a non-standard part) willinvalidate the pump’s safety certification.

6.7 Renewal clearancesAs wear takes place between the impeller and casingring the overall efficiency of the pump set will decrease.To maintain optimum efficiencyit is recommended thatrings are replaced and the impeller renovated when thediametral clearance detailed in section 3.5.2 hasdoubled.For WDXE and WDXS it is recommended to renovateor change line bearings when clearances havedoubled from those indicated in section 3.5.3.

6.8 Disassembly

Refer to section 1.6, Safety, and section 6.1Maintenance, before dismantling the pump.

Before dismantling the pump foroverhaul, ensure genuine Flowserve replacementparts are available.

Refer to sectional drawings for part numbers andidentification.

When dismantling, for convenience at reassembly,lay out all parts in the order in which they areremoved. Protect all machined faces against metal-to-metal contact and corrosion.Disassembly is preferably carried out with the pumpin a vertical position.

6.8.1 Initial procedure1. If bearings are oil lubricated, drain housings andremove oilers.

6.8.6 Disassembly of pump casingsAfter having dismounted bearings and shaft seals,unscrew the four tie rod nuts. The rest of dismountingis self explanatory when viewing the respectivesectional drawing.

For WDX pumps of construction M4 M5 M6 M7 (steelor stainless steel), an intermediate bushing isassembled at the middle of the pump. Take note of itsposition and on reassembly, assemble it in the sameplace.

6.9 Inspection of componentsWith pump dismantled, clean all parts and check forworn and damaged areas. Clean and inspect gasketand O-rings seals. Check wearing ring, interstageseal and balancing drum surfaces. Casing andimpeller wearing ring and interstage seal surfacesmay be either be part of the individual casing diffuserand impeller or separate parts. See sections 3.5.2and 3.5.3 for standard clearances for impellerwearing ring, interstage seal and balancing drum.

6.9.1 Precision surfacesCheck for damage to precision surfaces that locatecasings and bearing housings to preserve properinternal alignment. Check for corrosion due toleakage. Check axial impeller hub and sleevesurfaces for damage to insure proper axial alignmentof rotor.

6.9.2 Stuffing boxRemove any dirt or scale from stuffing box cavity.Replace O-ring seals. Replace gland studs if badlycorroded.

6.9.3 Mechanical sealsIt is not recommended that mechanical seals bereused. Using an old one leaves too much chance offailure to make the risk worthwhile, considering theusual cost of install ing and removing a pump from itssystem. Attempts to lap the mechanical seal facesmay be possible but require specialized technicalknowledge, skil ls and equipment beyond the scope ofthese instructions. Complete mechanical seal rotorsand seats are available from your FLOWSERVErepresentative as are any other repair parts.

6.9.4 Stuffing box sleev esCheck the stuffing box shaft sleeve outside surfacefor scoring. If used with packing, any scoring willshorten the life of the packing proportional to theamount of scoring present. If used with a mechanicalseal, the outside surface must not be scored in thearea where the seal rotor bellows or sealing ringtouches.

6.9.5 Ball bearingsIt is not recommended that the bearings be reused.However, if reuse is intended, clean bearings withpetroleum solvent or kerosene and inspect for anyindications of damage or wear, such as metalshavings, rust or surface galling. Further, judge thecondition of the bearings by rotating by hand.Replace any bearing which shows any sign ofdamage or that has been in service for an extendedperiod. Serviceable bearings should be spun in lightoil to completely remove the solvent after cleaning, orcoated by hand with an anti-corrosion agent if theyare not to be reassembled immediately and wrap atonce in clean oil proof paper while awaitingreassembly. The use of chlorinated solvents of anykind is not recommended in bearing cleaningoperations because of the rust hazard involved, nor isthe use of compressed air found desirable in cleaningoperations.

6.9.6 Diffusers and interstage casingsThere is normally no need to separate the diffusersand interstage casings, however, if they do becomeseparated, or new interstage casings or diffusers areto be installed, care must be taken to insure that thediffuser is seated (in contact) with the back surface ofthe interstage casing, and that the pin fits correctly inthe hole.

6.10 AssemblyTo assemble the pump consult the sectionaldrawings, see section 8, Parts list and drawings.

Ensure threads, gasket and O-ring mating faces areclean and that ball bearings are C3 fit. Apply threadsealant to non-face sealing pipe thread fittings.

Do not force when assembling the variouscomponents.Coat all fittings with an antifriction product.To assemble the pump, start from the suction side.

Assembly work should be preferably carried out withthe pump in a vertical position.To assemble the pump, reverse the dismantlingprocedures previously described, see the crosssectional drawings. Consult the sectional drawing toorganize the required operations. Replace allcomponents in their original place.

6.10.1 Shaft seal assemblyPacked Stuffing box:as per section 6.2.5.

Mechanical seal:Refer to assembly drawings for the seal and pump.Great care must be taken concerning the cleanlinessduring the mounting operation.Remove the surface protection of the rings just beforeinstallation.As some O-ring materials do not support grease oroil, water is preferred for easing assembling, wherecompatible with the product to be pumped.

6.10.2 Product lubricated bearings (WDXE/S)Install the bearing components after the whole pumphas been assembled; see sections 6.8.3.2 and6.8.3.3 for diagrams.- Put the sleeve onto the shaft end in taking care thatthe shaft pin fits into the slot.- Put the circlip [6544-01] in the shaft groove.- Install the bushing [3300] in the suction casing.

6.10.3 Anti friction bearingsAntifriction bearings should be preassembled so thatthe complete bearing set can be mounted on thepump casing. To do this, reverse the dismantling insections 6.8.2 and 6.8.3.
