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

1. Before opening the terminal box, please shut o the power supply to prevent power shock.
2. Before opening the coupling guards, please stop the pump first to prevent possible injury.
3. When installing the pump, please fix the foundation bolts vertically to prevent the pump falling over and
potentially hurting people.
4. Please fill grease in the pump when it’s required. For motor power is less than 5.5kW, it is free of filling
grease. For motor power is equal or bigger than 5.5kW, please fill grease every 5000 running hours.

V START-UP, OPERATION AND MAINTENANCE
1. Do not start the pump until it has been filled with water or liquid fully.
• Fill water in pump in inverse pouring system.
Close the pump outlet valve, release air vent screw on the pump head, and open the inlet valve
slowly until stable water flows from the air vent screw, then fasten the screw. Open the check
valve completely in the inlet pipeline.
• In open system, fill water in pump when liquid surface is lower than pump.
• Close the pump outlet valve, release air vent screw, and fill the liquid in pump through the air vent
screw hole until the pump and inlet pipeline are filled with water fully. Fasten the air vent screw
again.
2. Check the rotary direction.
Switch on the power supply and view the rotary direction by viewing the motor fan. The arrow on
the pump head indicates the correct direction of rotation. That is, from the motor end, pump shall
run counter-clockwise.
3. Check before pump start-up:
• Check whether the foundation bolt is fastened.
• Check whether the pump is filled with water fully.
• Check whether the voltage of power supply is correct.
• Check whether it turns correctly.
• To make sure all pipelines are connected tightly and can supply water normally.
• The valves in the inlet pipeline are completely opened and the outlet valve shall be opened slowly
after the pump is started up.
• Check the operation pressure if pressure meter is installed.
• Check all the controls for normal operation. If the pump is controlled by pressure switch, check and
adjust the starting pressure and stopping pressure. Check the full load current to make sure it does
not surpass the max current.
4. Frequency of pump starts.
Pumps should not be started too frequently. It is suggested the pump should not be started more
than 100 times per hour if the motor power is less or equal to 4kW. When motor power is larger than
4kW, pump shall not be started more than 20 times in one hour. If the pump starts and stops too
frequently, the control device shall be checked and adjusted to make the pump not start and stop
too frequently. Also it is necessary to check the installation.
5. Suggestion: When pump running, flow should be controlled at the range of 0.5-1.3 times of rated flow.
READ THE LABEL ON THE CYLINDER CAREFULLY BEFORE START-UP
NOTICE: A CHECK VALVE SHALL BE INSTALLED IN THE INLET PIPE.
CAUTION: DO NOT START THE PUMP UNTIL IT HAS BEEN FILLED WITH LIQUID FULLY
AND AIR VENTED. BE CAREFUL THE DIRECTION OF THE AIR VENT SCREW HOLE.
MAKE SURE THE FLOWING WATER WILL NOT HURT PERSONS OR PUMP OR ITS PARTS,
ESPECIALLY, PREVENT FROM HURTING FOR THE HOT WATER APPLICATION.

www.reefe.com.auAscento Group Australia P: 1800 807 604 VER.2023.08.09 13
6. Pumps which are installed according to this installation manual will work eectively and require little
maintenance.
• Mechanical seal will be adjusted automatically, the moving part and stationary part is lubricated and
cooled by the transferring liquid. When replacing the mechanical seal, the user needn’t disassemble
the motor for power bigger than 7kW.
• The bearing in pump is lubricated by the transferring liquid.
7. Frost Protecting
Pump can be used in the system with anti-frozen measures to water. If the pump is installed in an
easily frozen place, suitable antifreeze shall be added to the transferring liquid to prevent. pump
from being damaged. If antifreeze is not used, pump shall be stopped when it is frozen. Pumps which
are not being used should be drained.
8. The following should be checked regularly on the pump.
• Pump working and operating pressure.
• Possible leakage
• Possible motor overheating.
• Cleaning/replacement of all strainers.
• The switch o time of motor when overloaded.
• Frequency of starts and stops
• All control operation
If a malfunction is found, check the system according to “Fault finding and solution chart”.
9. The pump shall be cleaned and kept appropriately when it is not used for a long time.
10. Pump shall be prevented from being corrupted and damaged in storage
