DESCRIPTION and SPECIFICATIONS:
The GB Series pump is a portable horizontal multi-stage
pump designed for residential and agricultural washdown, misting and general boosting services.
The 304 stainless steel version of the GB is used for
HVAC, general commercial, reverse osmosis and filtration applications.
ENGINEERING DATA
PIPING
• Piping should be no smaller than the pump discharge
and/or suction connections. Piping should be kept as
short as possible, avoiding unnecessary fittings to minimize friction losses.
• All piping MUST be independently supported and
MUST NOT place any piping loads on the pump.
• All joints MUST be airtight. Use 3 – 4 wraps of
Teflon™ tape to seal threaded connections.
WIRING AND GROUNDING
Install ground and wire according
to local and National Electrical
Code requirements.
Install an all leg disconnect switch
near the pump.
Disconnect and lockout electrical
supply before installing or servicing pump.
Electrical supply MUST match pump’s name plate
specifications. Incorrect voltage can cause fire and/
or damage to the motor and voids warranty.
Motors not protected MUST be provided with
contactors and thermal overloads on single phase
motors, or starters with heaters on three phase motors. See motor nameplate.
• Use only stranded copper wire to motor and ground.
The ground wire MUST be at least as large as the wire
to the motor. Wires should be color coded for ease of
maintenance.
Pumps with open spray application must
be plugged into electrical service which is
protected by a Ground Fault Service Interrupter. Failure
to do so may result in serious personal injury or death
and property damage.
• Follow motor manufacturer’s wiring diagram on the
motor nameplate or terminal cover carefully.
WARNING

FAILURE TO PERMANENTLY
GROUND THE PUMP, MOTOR AND
CONTROLS BEFORE CONNECTING

• Maximum Liquid Temperatures: 160°F (72°C).
• Maximum Suction Pressure 75 psi.
• Pipe connections are 1" NPT suction and discharge.
¾" Hose Adapters are available.
• Capacities to 33 GPM.
• Heads to 600 Feet (260) psi.
• Rotation: Right hand, ie; clockwise when viewed from
motor end.
ROTATION
NOTICE: INCORRECT ROTATION MAY CAUSE
DAMAGE TO PUMP AND VOIDS THE
WARRANTY.
• Correct rotation is right-hand, CLOCKWISE when
viewed from the motor end.
• To reverse three phase motor rotation interchange any
two power supply leads.

SPLASHING OR IMMERSING OPEN
DRIP PROOF MOTORS IN FLUIDS
CAN SHORT OUT MOTOR AND
CAUSE FIRE, SHOCK, BURNS OR
DEATH.
• To REMOVE pump from service drain all pumpage
from pump and piping.
• To RETURN pump to service replace all plugs and pip-
ing using Teflon™ tape or equivalent on male threads.
• Refer to “OPERATION” section of manual.
NOTICE: PUMP MUST BE FULLY PRIMED BEFORE
OPERATION. DO NOT RUN PUMP DRY.
• After stabilizing the system at normal operating condi-
tions, check the piping. If necessary, adjust the pipe
supports.
Do not run pump dry; damage to me-
chanical seal will result. Do not run against
closed nozzle for prolonged periods or damage to pump
and piping will result.
HANDLE ASSEMBLY
Remove two top bolts from motor adapter. Insert them
through handle back into the motor adapter and tighten
securely.
NOZZLING
It is important to choose the right nozzle for proper
pump performance. The faucet supplying the water to
the pump should be checked to see what rate of flow it
will furnish. If the one min. flow with the faucet open is:
7 gals. — Use 6 gpm nozzle V2005
(which is included with each AM2)
6 gals. — Use 5 gpm nozzle V1502
5 gals. — Use 4 gpm nozzle SN0045 AM 7 Kit
4 gals. — Use 3 gpm nozzle V10152
By using this method of choosing nozzles we can keep a
positive pressure at the pump intake. This will keep the
pump from “robbing” water from other faucets.
DAIRY FARM USE
We recommend that all WaterGuns
®
used on farms
producing Grade “A’’ milk be equipped with a Vacuum
Breaker, installed according to instructions supplied with
Vacuum Breaker. This prevents sub-atmospheric pressure in the supply line even if the water supply should
diminish. We suggest the WaterGun be hung on a wall at
least 18" off the floor and that a hose rack be provided to
store the discharge hose off the floor.
MAINTENANCE
WARNING
Hazardous
voltage
FAILURE TO DISCONNECT AND
LOCKOUT ELECTRICAL POWER
BEFORE ATTEMPTING ANY
MAINTENANCE CAN CAUSE SHOCK,
BURNS OR DEATH.
• Motors have permanently lubricated bearings. No
lubrication is possible or necessary. Follow the motor
manufacturer’s recommendations for maintenance.
DISASSEMBLY
• Place wrenches on adapter (13) and discharge head (1),
and unscrew discharge head and casing (3).
NOTE: CASING HAS A LEFT HAND THREAD
ON BOTH ENDS AND IS SEALED WITH
O-RINGS (2).
• Remove klip ring (6) from end of shaft (11). The
stages, each comprising a bowl (9), impeller (8) and
diffuser (7) may now be removed. If pump has been
clogged by foreign matter, but otherwise undamaged,
further dismantling may be unnecessary. If shaft assembly (11), shaft seal (12) or motor are to be replaced,
proceed as follows:
• Remove plug (18) from rear of motor and hold
motor shaft with screwdriver. Unscrew pump shaft
coupling assembly (11) from motor shaft. Remove
four motor mounting bolts (14), separate the motor
from frame by withdrawing it straight back.
• Motor may have to be pried with two screwdrivers
if the shaft seal sticks. The shaft seal stationary seat
may be pushed out of adapter from the motor side.
There is a rubber coupling o-ring (19) between motor
shaft and coupling which will usually remain on the
motor shaft as the seal is pulled over it.
REASSEMBLY
Check that the rubber deflector (20) and the coupling
o-ring (19) are on the motor shaft. If they are worn or
damaged, replace. Install stationary seal seat in frame
(13) and mount frame (13) and handle (15) to motor.
Install seal rotating element, making sure faces are clean
and that the last rubber member goes over the coupling
o-ring and onto the motor shaft. Screw the pump shaft
and coupling assembly (11) on until it seats up against
the motor shaft. With a straight edge across the face of
the frame check the location of the outboard end of the
coupling. Due to variations in motor shaft length, etc., it
will be from .030" short to flush. Add .010" shims 7K155
until they are flush or higher, i.e., the last shim interferes
with the straight edge. Put the required stages on checking each stage for additional shim requirements by putting the straight edge across the bowl and checking the
location of the impeller hub. After all the stages are on
the shaft replace klip ring (6).
Check o-ring on both frame and discharge head and
replace if damaged. Install casing (3) and bearing spider
(4). Thread on discharge head (1) (Notice: left hand
threads) and tighten.

turn the unit over (clockwise) before replacing plug (18).
It should turn with no resistance except that of the shaft
seal.
