Self-priming pumps are designed to ensure econo-mic and reliable operation in all installations withdifficult access to the pumped liquid. The pumpsautomatically primes at empty and fully open suc-tion pipeline assembly. Possibility to control andmaintain the pump from the ground surface withoutthe need to take the pump out of the pit createscompetitive advantage. These pumps are extre-

mely universal, long life and wear resistant. Commonly used in all industrieswhere harsh environment creates requirements for reliability and functionalityat optimum level. Mud, sludge, drilling fluid, raw sewage, 76 mm in diametersolid handling selfpriming centrifugal pumps are the best choice for executionof variety liquid transfer projects. Pumps are made of ductile iron, grey iron,SST with oil flushed mechanical seals and bearings. Capacity ranges from 25m3/h for to 750 m3/h for single pump. Ability of having pumps mounted in pa-rallel or series configuration ensures flexibility and covers jobs were high ca-pacity at high head is required. Pump units are skid mounted with forkliftpockets and central lifting eye for easy and safe handling on site. Double bo-unded enclosure is for “spill free” operations. Reductions of noise up to 59 dBfor variety of pump units. Our self-priming pumps are produced by Gorman-Rupp, IPT, and AMT. We use motors from WEG, Tamel, Celma and combustionengines from John Deere, Caterpillar, JCB, Yanmar, Deutz, Honda, Perkinsand ListerPetter.

CHOOSING A PUMP TECH-POMPSERWIS Sp. z o.o.


Before choosing a pump certain facts should be determined. Points below sho-uld prove helpful in gathering necessary information.1. GeneralType of application, pumped liquid, de-tails and operating environment de-scription.

2. CapacityYou should determine required capa-city of complete pumping system atthe end of discharge line.

3. Static liftDifference in levels between pumpedliquid and discharge point.

4. Static suction liftDistance between level of pumped li-quid and the axis of pump’s impeller.

5. Hydraulic friction losses In order to enable us to calculate hyd-raulic losses we need to know:a)The length and diameter of suction

and discharge pipelines, as well asthe material they are made of.

b)Differences in levels between pum-ped liquid and discharge point.

c) Number and type of fittings, cros-sings and other flow obstaclesalong discharge pipe.

d)Type of pumped liquid.

6. Required pressure on the end ofdischarge pipe and actual pressurevalue on the surface of the pumped li-quid.

7. Total dynamic head= Static lift + suction lift+ value of hydraulic losses+ required pressure at the end of the

pressure pipeline

8. Characteristics of the pumped liquid

a) densityb) viscosityc) temperatured) corrosiveness and/or abrasive fea-

turese) type, concentration and maximal

size of solids in the pumped liquid

ASSEMBLY AND OPERATION



99

Guidelines:* Pump should be places on a flat and stable surface.* Check the alignment of the pump with the motor/engine.* The pump should be placed as close as possible to the pumped liquid.* The suction pipeline should not be lead upwards from the pump.* Check the sealing of all connections and fittings, paying special attention to

the suction side* The lesser the suction height is, the greater capacity of the pump can be

achieved.* The pump should not be used longer than a few minutes at closed valve on

the pressure side.* The working conditions should be regularly checked on the adequate gauges

on suction so as discharge side of the pump.* In the case of operation outside of performance range pump will work in ca-

vitation and will get damaged. Consult us for details. * The pumps, fittings, hoses, pipes and accessories should never be used for

pressures greater than the nominal pressure values of a given device.* Oil levels in the mechanic seal chamber, and the bearing chamber should be

monitored at least once a day.* Do not pump flammable liquids, unless the pump is dedicated to this pur-

pose.* Check the correctness of the pump’s circuit direction.* Make sure that the suction pipeline is sufficiently submerged, and there is no

vortexing.* If the pump is working at great delivery heads, discharge check valve has to

be used. * In the case of self-priming pumps you should fill the body of the pump casing

with liquid before starting the pump, vacuum-assisted pumps do not requireformer filling.

* n the case of pumps with combustion engines, the engine should be turnedon once a week for at least 5 minutes to be properly maintained during standby.

ASSEMBLY AND OPERATION TECH-POMPSERWIS Sp. z o.o.


* All kind of valves has to be operated with gradual and slow movement toavoid water hammer.

* Monitor oil in the pumps and the engines at least once a day. In combustionengines oil and filters should be changed every 400 hours of operation. Whenchanging the oil in combustion engines there is also a need to change theoil, fuel and air filters. TPS company, at Client’s request, provides full main-tenance and repair procedures on site around all EU countries.

* In case of freezing temperatures during standby it is forbidden to leave fluidsin pumps and pipelines. This may lead to damages to the equipment. TPSoffer heating so as liquid circulation solutions for cold weather environments.

* Pumping high temperature liquids is allowed only via dedicated pump models.Standard pump can pump liquids of temperature not exceeding 70°C.

* Changing the pump’s operating parameters. This can be achieved in twoways:1) Partially closing the pressure side’s valve; this leads to generating an ad-

ditional hydraulic loss.2) Changing the speed of the pump’s shaft- switching the engine to higher or

lower speed (see page 105).* During manipulation of the pump speed it is necessary to keep the rotation

speed within the limits of the pump’s performance curve and available powerof the drive.

* Special attention should be paid to pipelines and fittings in order to adjustthem to the type of pumped liquid and the operating pressure of the completesystem.

PUMP AND DRIVE ALIGNMENT TECH-POMPSERWIS Sp. z o.o.


Coupling the pump and drive through direct coupling.

Coupling the pump and drive through v-belt.

Most commonly used forms of coupling drives together with pumps are elasticcouplings or v-belts and pulleys. Some of the pump units are equipped withgear reducers or hydrokinetic clutches. In order to ensure proper functioningof the pump unit assembly it is necessary to align pump and drive. As a resultof transportation, long operation, excessive vibrations, the assembly may loseits alignment. It is always necessary to check this before putting the unit towork. In case of loss of alignment it is required to correct it using adequatetools. Our service unit is equipped with extensive experience and equipmentto do measure and set the alignment correctly.

PIPELINE CONNECTION TECH-POMPSERWIS Sp. z o.o.


The use of manometer and vacuum meter enables to track the operating pa-rameters of the pump set. In case of using self-priming pumps or vacuum-as-sisted pumps there is no need to use suction check valves at the ends of suctionpipelines. Both types of pumps start the suction process without the need to fillthe suction pipeline with fluid. Pipelines should be supported independentlyfrom their fastening with the pump. The end of the suction pipeline should besituated on a proper depth in order to avoid vortexing. Suction pipeline shouldnot lie on the bottom of the tank. At the discharge side of the pump there is aneed to use a non-return valve to secure from returning of the pumped liquid.The gate or ball valve can prove helpful during operation of the liquid transfersystem i.e. to reduce the flow or in the case of pump working in discharge ca-vitation to force additional hydraulic loss. In stationary installations it is advisedto use elastic compensators on both sides of the pump to reduce vibrationspread to pipework. A useful element is also an air release valve on the dis-charge side of the pump to avoid forcing air to the discharge pipeline. It is ad-vised to avoid leading the suction pipeline horizontally. It is recommended touse suction pipelines with diameters larger than the diameter of the suctionflange on the pump.

DELIVERY HEIGHT



105

Components to measure the total dynamic delivery height:1. Linear and local hydraulic losses in the suction pipeline (points 1, 3).2. Level gap between the level of the pumped liquid and the axis of the pump shaft (point 2).3. Linear and local hydraulic losses in the discharge pipeline (points 4, 7).4. Level gap between the axis of the pump shaft and the highest point of the pressure

pipeline (point 5).5. Pressure required at the end of the pressure pipeline (point 6).

Hydraulic losses:Linear- liquid passing through the pipeline by touching its internal surface en-counters friction resistance. The value of the resistance depends on the flowspeed of the liquid and the roughness of the internal surface of the pipeline.The greater the speed is, the bigger are the losses. The greater the roughnessis, the bigger are the losses (roughness is dependent on the material whichthe pipeline is made of i.e. materials from plastics have low roughness whencompared to, for example, pipes made of cast iron).Local- in order to include the value of the local hydraulic loss resulting fromused fittings (i.e. valve, bend, reduction etc.) it is necessary to assume, for thesake of simplification, that the loss amounts to 20% of the linear hydraulic loss.

PERFORMANCE CHARACTERISTIC



107

The knowledge about the pump’s performance curve is necessary for its properuse. Hydraulic performance of the pump is presented in the form of a chart withthe following parameters of the pump’s performance: delivery head- H, Capa-city- Q, total power requirement - N, efficiency- n, NPSHr. Pump characteristicsis determined empirically, and allows for creating a chart presenting the opera-ting range of a given pump model. Using the pump in duty point outside theoperating range may lead to cavitation.Hydraulic power required for the pump to deliver sufficient energy for the liquidto overcome the total dynamic delivery head.Total power required - including losses from the type of drive used.Pump performance is a percent of the energy transferred to the pump shaft inrelation to the energy transferred by the pump to the pumped liquid. Pump per-formance oscillates between 20% and 95%, and depends on the pump type,its shape, type of the imeller, free flow of spherical solids through the pump,and the location of the duty point on the pump’s performance curve.

ROTATIONAL SPEED TECH-POMPSERWIS Sp. z o.o.


The chart above presents 3 curves characterising the operation of the pumpfor different rotational speeds of the drive. Performance curves with differentrotational speeds of the engine are parallel. The greater the rotational speed is(for the same engine), the greater the delivery head and the capacity are. Inelectrical motors it is possible to change the rotations with the use of frequencyconverters installed on the control panel. Our combustion engines are alsoequipped with speed controls. Owing to the possibility of changing the rotationspeed it is possible to adjust the operating parameters, in a defined range, tothe current installation requirements, and by doing this to save precious energy.

RELATIONSHIP BETWEEN DELIVERY HEAD AND EFFICIENCY, AND THEROTATIONAL SPEED OF THE ENGINE

PUMP AND PIPELINE



109

Duty point of the system pump-pipeline is determined by the system curve of thepump performance characteristics with the pipeline’s characteristics. The systemcurve, in other words the pipeline characteristics, is the relationship of the hyd-raulic losses in the flow function. The greater the flow, the greater the hydrauliclosses are. Having a pipeline with a fixed diameter and roughness, and the ope-ration parameters of the pump, enables us to determine the factual duty point ofthe system (pipe + pipeline). It is crucial from the point of view of choosing anoptimal solution. Point A on the chart is determined for the pipeline that is on thesame level as the pump, meaning that the static delivery head equals 0. Point Bdetermines the point of the system operation for the pipeline that is higher thanthe level of the pumped liquid, meaning that the static delivery head is H>0. Forthe point C, the pipeline is situated at the same level as on the curve B, yet inthis case there is more liquid or the pressure pipeline has a smaller diameter -the flow speed is raising which results in greater hydraulic losses. Determiningthe system duty point is a crucial aspect of the pressure transfer of liquids withthe use of pumps and pipelines. Our experience, as well as close cooperationwith our Clients at the stage of design or evaluating the service costs, results inthe proper, on-time, and successful choice and execution of the project.

PUMP-SUMP (PIT), NPSH TECH-POMPSERWIS Sp. z o.o.


NPSH- Net Positive Suction Head parameter, is a very important operation pa-rameter from the point of view of proper selecting, and therefore proper func-tioning of the pump and pipeline system. When selecting the system we payspecial attention to this matter. Omitting this aspect may lead to operation incavitation which has a negative influence on the lifetime of the pump as wellas other components of the system.

CAVITATION



111

If the pumped liquid’s pressure falls below the evaporate pressure value in thesuction pipeline, the vacuum migrates with the flow. The vacuum areas disap-pear when they encounter higher pressure areas inside the pump. Strong dy-namic change of the pressure value makes the liquid strike, with high speed,the operating components of the pump. It is followed by a dynamic increase ofpressure, together with high pressure on small surfaces, exceeding the steel’sdurability parameters. As a result we get erosion of the pump’s operating ele-ments, and high-frequency vibrations. This situation is harmful for the engineand the pump’s rotary assembly. Cavitation manifests in loud running of thepump, and losses of the nominal operational parameters. In order to preventcavitation, the NPSHr (given in the technical specification) and NPSHa (resul-ting from calculations) parameters should be analysed. In addition, there is aneed not to exceed the maximum suction head, use only the suction pipelineswhose diameter is bigger than the diameter of the pump’s suction flange, keepthe suction line permeable, not to use unnecessary fittings, omit horizontal sec-tions of the suction pipeline. There is also a risk of pump’s operation in cavitationon the pressure side. Such situation may take place when the pump has toolow discharge head on the pressure side. You only need to reduce the flow byclosing partially valve on the pressure side to increase the hydraulic loss, andas a result to move the duty point of the pump to the performance range.

It is a sum of the volumes of liquids pumped by all pumps in the sys-tem, and its value also depends on the inclination of the system curve. Theamount of the systems pressure remains the same. The efficiency depends onthe delivery head of the pump whose parameter in the system is the highest.

There are many matters connected with the characteristics of the pumped li-quid, and the installation that have an influence on the maximum suction height.Below you will find a short list of important elements to which you should payattention in order to pass information to us that will allow us to choose suitablesolution:Pressure on the surface of the pumped liquidThe place from which the liquid is going to be pumped may not always haveatmospheric pressure- there may be overpressure or negative air pressure if itis closed.Evaporation pressureMixtures of hydrocarbon and other light liquids, or liquids with raised evapora-tion temperature evaporate faster than water in vacuum conditions which hasan influence on the maximum suction lift.Density and specific gravity of the liquidHigh density of the pumped liquid influences the maximum suction lift.Viscosity and hydraulic lossesThese elements also influence the maximum suction headFlooded suction/ Static suction lift Work with flooded suction has a positive influence on the pump performance,static suction lift has to be included in the calculations of total dynamic deliveryhead.The above information will enable us to calculate the NPSHa (Net Positive Suc-tion Head Available) cavitation surplus. Each pump has limitations in terms ofthe maximum suction head. This parameter is described on the performancecurve of each pump, and under the abbreviation NPSHr (Net Positive SuctionHead Required). In all installation the NPSHa value has to be higher thanNPSHr in order to ensure proper functioning without the risk of cavitation.
