INTRODUCTION
This Installation, Operation, and Maintenance Manual is designed to help you get the best performance
and longest life from your RAE pump.
This pump is a GMVCP Series vertical multistage centrifugal pump. This pump should be immersed
during operation.
GMVCP Series pumps are intended for industrial use to carry fluids such as water, coolant, light oil and
other clean, non-aggressive liquids.
Standard pump construction is stainless steel immersed parts.
If there are any questions regarding the pump or its applications which are not covered in this manual,
or in other literature accompanying this unit, please contact your RAE Pumps distributor, or write:

For information or technical assistance on the power source, contact the power source manufacturer’s
local dealer or representative.
! DANGER !
This pump is not intended to transfer explosive liquids, such as gasoline, diesel oil and other
similar liquids. It is only suitable for water, and diluted, low viscosity, non-corrosive cooling or
lubricant liquids.
SPECIFICATIONS–SECTION A
MODEL CODE EXPLANATION
The pump models are coded based on the
number of pump stages. Standard stages
consist of both diffusers and impellers. Some
models contain null stages for special
installation considerations. Null stages consist
of only the diffuser chamber.
The number of stages is followed by a zero in
the model code. This zero is not part of the
stage count number. The pump model is shown
on the pump nameplate.

INSTALLATION–SECTION B
! WARNING !
When running, the motor surface
temperature is extremely high. Mount pump
in a safe place to avoid accidental touch.
REQUIREMENTS
1. The pump should be located in a well-
ventilated but frost-free area.
2. Immersion depth should be as deep as
possible, but not less than the minimum
Submerged Depth listed in SECTION A of
this manual to prevent dry running and
damage to the pump.
3. When installing the drainage pipe, support
pipe weight to avoid strain on the pump and
twisting of the pipe.
4. Motor should be correctly grounded. Pump
can be damaged by phase loss, unstable
power or power surge.
5. Install a pressure meter on pump outlet to
monitor pump operation.
ELECTRICAL CONNECTION– SECTION C
! WARNING !
Electrical installation should be carried
out in accordance with the local
electrical code. Make sure that the
electricity supply has been switched off
before electrical connection.
Use care when accessing pump
electrical components.
SPECIFICATIONS
Electrical specifications (voltage, hertz) are
shown on the pump nameplate. Verify that the
power supply voltage and hertz match pump
requirements. An external ON/OFF switch must
be installed.
CONNECTION
Electrical connection should be in accordance
with diagram shown on the connecting box, and
motor current should be within rated amps as
shown on nameplate. Three phase pump
requires extra magnetic starter with protection.
ROTATION DIRECTION
On this three phase motor, rotating direction is
critical. The rotating direction is indicated on the
fan cover (counterclockwise viewing from fan
cover end). Interchanging any two leads with
power off can reverse the pump rotation.

5

POSITIONING CONNECTION BOX
The position of the motor connecting box is
adjustable. Referring to Figure 3, the position
can be changed by removing the motor fan
cover, unscrewing the frame bolts, and turning
the motor casing and connecting box
subassembly together to proper position.
Finally, screw the frame bolts tight, and put the
fan cover back.

OPERATION AND MAINTENANCE–SECTION D
! WARNING !
The pump cannot be operated with
discharge outlet fully closed. Doing so
will raise the liquid temperature
abnormally, and quickly damage pump.
! WARNING !
The pump cannot be used to transfer
explosive liquids.
Extra protective gear is required if the
working liquid temperature exceeds
140°F to avoid scald hazard.
The pump should not be used to transfer
toxic or contaminated liquid. Warranty
will be void if the pump application is not
in compliance with the installation and
operation procedures.
FINAL CHECKS
Before starting the pump, verify:
1. Pump rotation–the rotating direction
should be counterclockwise viewing
from fan cover end.
2. Piping and joints are fitted carefully to
prevent leaks.
3. Check that foot and air vent bolts are
secure and tighten if loose.
4. The pump has been filled with liquid and
air vented as described in the START
UP instructions below. Failure to do so
will damage the bearing and mechanical
seal.
5. The suction filter is clear of obstruction.
START UP
1. Start motor, verify motor is turning and
is turning in the right direction.
2. Open outlet valve, adjust it to the
required working condition. Suggested
flow is 0.5 to 1.3 times of the pump’s
rated flow.
3. Check pressure meter on pump’s
discharge for fluctuations in pressure
and observe pump for vibration. If
pressure drops/vibration indicate air in
the liquid, loosen air vent bolts to vent
air, retighten bolts once pressure
stabilizes and vibrations stops.
4. Observe for changes in the sound of
pump operation. If there are any
abnormal noises, pump should be
stopped and checked immediately.
SHUT DOWN
1. Close outlet valve slowly.
2. Switch off the power.

6

! WARNING !
Avoid frequent pump shut down and
start up.
Pumps with a motor power equal to or
less than 5HP should not be restarted
more than 100 times per hour. Pumps
with a motor power greater than 5HP
should not be restarted more than 20
times per hour.
MOTOR LUBRICATION
For motor powers less than 7.5HP,
lubrication is not needed. For motor power
equal to or greater than 7.5HP, fill grease
every 5000 running hours.
SUCTION FILTER
For maximum performance, the suction filter
should be always kept clean and free from
obstructions.
PERIODIC INSPECTION
The following checks should be carried out
periodically to ensure normal operation:
1. Measure the discharge and output
pressure.
2. Inspect piping and joints for leaks.
3. Measure motor temperature for
changes.
4. Examine the motor starter/container.
TROUBLE SHOOTING–SECTION E
