boosting of cold or hot clean liquids.

-XVM In systems where all parts in contact with the

liquid must be made of high-grate stainless steel,

XVM pumps must be used.

4.Technical data4.1 ambient temperature

Maximum +40 . If the ambient temperature exceeds

+40 or if the motor is located 1000 metres above sea

level, the motor output(P ) must be reduced due to the 2

low density and consequently low cooling effect of the

air(Figure 1). In such cases, it may be necessary to use

a motor with a higher output.

Fig.1 Relationship between motor output (P ) and 2 ambient temperature

4.2 Liquid temperature

See fig.5, page 4, which indicates the relationship

between liquid temperature and maximum permissible

operating pressure.

Note: The maximum permissible operating pressure

and liquid temperature ranges apply to the pump only.

4.3 Maximum permissible operating pressure and

liquid temperature for the shaft seal

4.4 Minimum inlet pressure

The maximum suction lift in metres head can be

calculated as follows:

H=Pb 10.2-NPSH-Hf-Hv-Hs

Pb = Barometric pressure in bar.(Barometric pressure can

be set to 1 bar). In closed systems, Pb indicates the

system pressure in bar.

NPSH = Net Positive Suction Head in metres head

(to be read from the NPSH curve on page 18 at

the highest flow the pump will be delivering).

Hf = Friction loss in suction pipe in metres head at the

highest flow the pump will be delivering.

Hv =Vapour pressure in metres head.

Hs = Safety margin = minimum 0.5 metres head

4.5 Maximum inlet pressure

Figure 2. shows the maximum permissible

inlet pressure. However, the actual inlet pressure+

pressure when the pump is running against a closed

calve must always be lower than the maximum perm-

issible operating pressure.

4.6 Minimum flow rate

Due to the risk of overheating,the pump should not be

used at flows below the minimum flow rate.

The curve below shows the minimum flow rate as a

percentage of the nominal flow rate in relation to the

liquid temperature.

5. Installation When installing the pump. Follow the procedure

below in order to avoid damaging the pump.

Step Action

Arrows on the pump base show the direction of flow of liquid through the pump

-Dimension of the base-Pipework connection-Diameter and position of foundation bolts

The pump can be installed vertically or horizontally.Ensure that an adequate supplyof cool air reaches the motor cooling fan. However, the motor must never fall below the horizontal plane.

Install the pipes so that air locks are avoided, especiallyon the suction side of the pump.

In the case of installation in which:-The discharge pipe slopes downwards away from the pump.-There is a risk of siphon effect-Protection against backflow of unclean liquids is necessary.A vacuum valve must be fitted close to the pump.

The pump is available to install outside, but there is suitable protection.

To minimize possible noise from the pump, it is advisable to fit expansion joints eitherside of the pump and anti-vibration mountings between foundation and pump.Isolating valves should be fitted either side of the pump to avoid draining the system ifthe pump needs to be cleaned, repaired or replaced. The pumpmust always be protected against backflow by means of a non-return valve (foot valve)

6. Electrical connection The motor should be grounding.

Before removing the terminal box cover and

before any removal/dismantling of the pump,

make sure that the electricity supply has been

switched off.

Single phase motor incorporate a thermal

protector, Three phase motor must be

connected to a motor starter.

The electrical connection should be carried

out by an authorized electrician in accordance

with local regulations.

The operating voltage and frequency are marked on the

motor nameplate. Make sure that the motor is suitable for

the electricity supply on which it will be used.

As standard the terminal box is mounted on the suction

side of the pump.

Terminal box can be turned to four positions, in

,steps:

1.If necessary, remove the coupling guards, Do not

remove the coupling.

2.Remove the bolts securing the motor to the pump.

3.Turn the motor to the required position.

4.Replace and tighten the bolts.

5.Replace the coupling guards.

The electrical connection should be carried out as shown

in the diagram inside the terminal box cover.

Table 1: Motor noise

Before replacing the drain plug in the base, screw thebypass valve out against the stop. See fig.6. Fill the drain plug by tightening the large union nut followed by the bypass valve.

7.start-up Read the warning mark before start-up. Note: Do not start the pump until it has been filled with liquid and vented. If the pump runs dry, the pump bearing and the shaft seal may be damaged. Pay attention to the direction of the vent hole and take care to ensure that the escaping water does not cause injury to persons or damage to the motor or other components. In hot-water installation, special attention should be paid to the risk of injury caused by scalding hot water.

XVM 1,2,3,4,5

For these pumps, it is advisable to open the bypassvalve during start-up. The bypass valve connects the suction and discharge sides of the pump, thus making the filling procedure easier. When the operation is stable, the bypass valve can be closed. When pumping liquids containing air, it is advisable to leave the bypass valve open if the operating pressure is lower than 6 bar.If the operating pressure constantly exceeds 6 bar, the bypass valve must be closed. Otherwise the material at the opening will be worn because of the high liquid velocity.

Drain plug

Bypass valveFig 6

Check below procedures before starting pump- Tighten foundation bolt.- Pump fill with water.- Voltage is right.- Turn the motor to the required position.- All pipes are connect tightening under normal water supply.- Inlet pipe 's valve is open; Outlet valve will be opened after pump starting.- Heck the working pressure if installed pressure gage.- Check controller. If pump is controlled by pressure switch, check and adjust on/off pressure. Through pressure switch, check motor's Ampere that no more than admitted Ampere.

8. Maintenance Before starting work on the pump, make sure that all power supplies to the pump have been switched off and that they cannot be accidentally switched on. Pump bearings and shaft seal are maintenance-free.

Motor bearingMotors which are not fitted with grease nipples are maintenance-free. Motor fitted with grease nipples should be lubricated with high-temperature lithium-based grease. See the instruction on the fan cover. In the case of seasonal operation (motor is idle for more than 6 months of the year). It is recommended to greasethe motor when the pump is taken out of operation.Intall the pump according to the instruction makes pumpwork effectively and less maintenance.-Mechanical seal auto adjust,interface between stationary ring and rotation ring lubricated and cooled by the pumping liquid.-Sliding bearing lubricated by the pumping liquid.

9. Frost protection Pumps which are not being used during periods of frost should be drained to avoid damage. Drain the pump by loosening the vent screw in the pump head and by removing the drain plug from the base. Care must be taken to ensure that the escaping water does not cause injury to persons ofdamage to the motor or other components. In hot-water installations, special attention should be paid to the risk of injury caused by scalding hot water. Do not tighten the vent screw and replace the drain plug until the pump is to be used again.

10. ServiceNote: If a pump has been used for a liquid which is injurious to health or toxic, the pump will be classified as contaminated. If EBITT is requested to service the pump, EBITT must be contacted with details about the pumped liquid, etc. Before the pump is returned for service. Otherwise EBITT can refuse to accept the

pump for service.Possible cost of returning the pump are paid by thecustomer. However, any application for service (no matter to whom it may be made) must include details about the pumped liquid if the pump has been used for liquids which are injurious to health or toxic.
