READ THIS MANUAL CAREFULLY BEFORE INSTALLATION AND BEFORE STARTING THE PUMP.

APPLICATIONS AND CONDITIONS

Pumps of REEFE VMR models are non-self-priming vertical multistage centrifugal pumps. Their features

are high eciency, low noise, light corrosive liquid resistance, compact structure, good appearance, small

volume, light weight, easy to service, good seal performance, and covered by REEFE warranty and customer

service.

i. Applications

• Pumped liquids: low viscosity, neutral, non-explosive liquids. Not containing solid particles or ﬁbers.

The liquid must not be of a corrosive nature thereby being capable of attacking the pump materials

chemically.

• Boiler water supply and condensing system.

• Water treatment, ﬁltration system.

• Food and beverage industries.

• Pressure boosting in high-rise buildings.

• Farmland irrigation, nursery irrigation and golf court irrigation.

• Industry cleaning system.

• Liquid conveying, circulation and boosting.

• Hot and cool water.

ii. Operation Conditions

• Medium temperature: Normal temperature type -15°C+70°C; Hot water type-15°C~ +120°C.

• Flow: 0.4~180m3/h

• Medium pH range: pH 5-9.

• Maximum ambient temperature: +40°C.

• Maximum altitude: 1000 m; derate when higher.

• Minimum inlet pressure: Refer to catalogue for speciﬁc model of pump.

Caution: When pumping liquids with a density and/or viscosity higher than that of water, use motors with

correspondingly higher outputs, if required.

PUMP INSTALLATION

1. The pump should be sited in a well-ventilated and frost-free position. The distance between the pump-

motor and other objects should be at least 150mm, to cool the motor by fan with enough air.

2. To reduce the head loss of inlet as least as possible, the inlet pipe shall be as short as possible.

3. Ensure the check valve is installed in pipeline system before the pump installation. If pump is used for

boiler water supply, a check valve must be installed in the piping between pump and boiler.

4. Pump shall be installed in cement base or other similar base with suitable height. It can also be installed

in ﬁxed grounds or ﬁxed brackets on the wall. Pay attention not to let the weight of pipe system on pump

to prevent pump from damage.

5. The arrow on the inlet and outlet chamber shows the direction of ﬂow of liquid through the pump. Check

whether the liquid can ﬂow easily before starting the pump.

6. Before pump installation. the inlet pipeline shall be cleaned. If there are impurities in the pipe, it is

necessary to install a strainer at 0.5-1m in front of the pump inlet (particularly recommended for pump

with ﬂow less than 8m3/h).

7. Air locks shall be avoided when installing the inlet pipeline. see Fig 3.

8. If the outlet globe valve might be closed (or the ﬂow is decreased to zero), a bypass shall be installed in

outlet pipeline to ensure adequate lubricating and cooling water to pass the pump.

ELECTRICAL CONNECTION

1. The electrical connections should be carried out by an authorized electrician.

2. To make sure the motor is suitable for the power supply, cables of the motor must be connected to the

power supply according to the Fig. on the terminal box and the motor nameplate.

3. The motor must be connected to a fast and eective motor starter to ensure that the motor will not be

damaged by lack of phase, unstable voltage, or overload. Tho motor shall be earthed reliably.

Figure 3.

Caution: When installing, the motor is not allowed to be hung upside down.

Caution: Before taking the terminal box cover apart or dismantling the

pump, make sure that the power supply is switched o.

WARNING - ELECTRICAL CONNECTION AND SAFETY DEVICES

1. The pump units should be connected to the power supply by the appropriately rated power cables

according to the motor ratings.

2. The pump units should always be equipped with safety devices as required in the standards (EN 809

and/or EN 60204-1) as well as by the national rules of the country where the pump is used.

3. Despite the rules of any country, the power supply to the pump unit must be equipped with at least

following electrical safety devices with appropriate ratings:

• Emergency switch

• Circuit breaker (as a supply disconnecting (isolating) device as well as an over-current protective

device)

• Motor overload protection
