Pressure Booster Pumps
Description
Unpacking
Pressure booster pumps increase water pressure from city mains or private water sys-
tems. Applications include providing high water pressure for washing buildings, dairy
walls or floors, hog parlors, poultry houses, rinsing or spray cooling equipment, lawn
sprinkling and insecticide spraying. Stainless steel models can handle salt-water and
contaminated water in reverse osmosis filter and other aggressive water applications.
When unpacking the unit, inspect care-
fully for any damage that may have
occurred during transit.
NOTE: Use pump with clear water
only.
Single-phase models are equipped with a capacitor start, thermal protected motor.
Three-phase models require separate overload protection.

Pre-Installation
IMPORTANT: Indicates factors concerned with operation,
installation, assembly or maintenance which could result in
damage to the machine or equipment if ignored.
NOTE: Indicates special instructions which are important but
are not related to hazards.
HANDLING
1. Use handle supplied to lift pump.
2. Avoid impact on pump or motor. In particular, avoid
impact on discharge end of pump or rear motor access
cover.
!
LOCATION
Wire motor for correct voltage. See
“Electrical” section and Motor Data Charts
C&D of this manual, and motor nameplate.
!
In any installation where property dam-
age and/or personal injury might result from an inoperative
or leaking pump due to power outages, discharge line block-
age, or any other reason, a backup system(s) should be used.
1. Locate pump as close to the fluid source as possible, keep-
ing the inlet pipe short as possible.
2. Place unit where the pump and piping are protected from
the weather and extremes of heat, humidity and below
freezing temperatures.
3. Mount unit in a dry location that is easily accessible for
inspection and maintenance. If a dry location is not avail-
able, mount it on a foundation well above the wet floor.
4. Allow ample clearance around unit for free air circulation.
SUCTION LIMITATIONS

or damp surface or in water.
Follow wiring instructions in this manual when connect-
ing to power lines.
1. Units are non self-priming.
2. Pressure booster pumps are not recommended for suction
lift applications.
!
Always disconnect power source before
performing any work on or near the motor or its connected
load.
PIPING
1. Use galvanized piping, rigid plastic or other suitable pipe
that will not collapse under suction or rupture due to pres-
sure.
Do not use to pump flammable or explosive fluids
such as gasoline, fuel oil, kerosene, etc. Do not use in flam-
mable and/or explosive atmospheres.
If hose is used, make sure it is the rein-
forced industrial type that is rated higher than the shutoff
pressure of the system. Ordinary garden hose will collapse
and starve the pump of water.
2. The diameter of the inlet and discharge pipe should be
no smaller than the corresponding ports of the pump (See
Figure 1). Smaller pipe will reduce the capacity of the
pump. Increase pipe size on long runs.
3. Avoid air pockets in inlet piping or air will accumulate at
high points, making priming difficult.
Hazardous pressure! Install pressure relief valve in
discharge pipe. Release all pressure on system before work-
ing on any component.
1. Make workshop child proof - use padlocks, master
switches; remove starter keys.
2. Wear safety glasses when working with pumps.
3. Wear a face shield and proper apparel when pumping
hazardous chemicals.
4. Use pipe compound on all joints and connections. Use
Teflon tape or plastic joint stik, on plastic pipe. Draw all
pipe up tightly.
4. Keep work area clean, uncluttered and properly lighted;
replace all unused tools and equipment.
IMPORTANT: The entire system must be air and water tight
for efficient/proper operation.
5. Provide guarding around moving parts.
6. Keep visitors at a safe distance from the work area.
7. Periodically inspect pump and system components.
8. Protect electrical cord. Replace or repair damaged or
worn cords immediately.

PRESSURE BOOST SYSTEMS
1. On pressure boost systems, locate
the pump so that there will always
be a positive supply of water to the
pump (See Figures 6, 7 and 8).
2. For service convenience, install a
gate valve and union in the inlet
and discharge line.

Three phase models are factory connected for 230V at
the motor.
c. If the motor wiring must be changed to conform to your
specific voltage requirements then the motor, pressure
switch or other controls should be rewired to conform
to one of the wiring diagrams (either 115V or 230V,
single phase; 230V or 460V, three phase). Single phase 3
HP motors are 230V only and cannot be wired for 115V
service.

or operating pump. Failure to do so can result in personal
injury.
Figure 11 - Wiring Diagram for Three Phase Motors
IMPORTANT: Do not use an extension cord or splice wires.
Joints should be made in an approved junction box. If the
above information or the following wiring diagrams are con-
fusing, consult a licensed electrician.
8. All units are not supplied with pressure switches, float
devices, on/off switches, or the like (control devices).
Controls should be wired in at this time, utilizing whatever
instructions come with the controls. All units supplied
with cords, will run whenever cord is plugged into power
and will turn off whenever cord is disconnected from
power.
Operation
Unit must be full of fluid before operat-
ing. Do not run dry, or against a closed discharge. Do not
pump dirty water or abrasive liquids. To do so will cause
pump failure and will void the warranty.
VALVES
The inlet valve should be in the full open position and the
discharge valve should be partially open, permitting some
back pressure to be exerted against the pump when starting
up. Open valve after start up is completed.
PRIMING
MOTOR PROTECTION
All single phase motors have built in thermal protection for
all voltages. The overload protects the motor against burn-
out from overload of low voltage, high voltage and other
causes. The device is automatic and resets itself once the
temperature has dropped to a safe point. Frequent tripping
of the device indicates trouble in the motor or power lines
and immediate attention is needed.
NOTE: Before starting the pump it is absolutely necessary
that both the pump and the inlet pipe be completely
filled with water.
PRESSURE BOOST INSTALLATIONS
Priming is automatic when pump is connected to a pressure
source such as a hydrant or city main (See Figures 6, 7 & 8).
1. Open valves or nozzle on inlet and discharge side of pump.
!
Never examine, make wiring changes or
touch the motor before disconnecting the main electrical
supply switch. The thermal device may have opened the
electrical circuit.
2. To relieve trapped air, allow water supply to run a mini-
mum of 30 seconds before starting the pump.
IMPORTANT: An adequate flow of water going into the
pump is required so that the pumps impellers and shaft seal
do not run dry and fail.
3. If you installed a pressure gauge at the pump inlet, a read-
ing of 2 psi minimum should show whenever the pump is
in operation (See Figures 6, 7 & 8).
Three phase motors do not have a built in thermal protec-
tion. It is recommended that a properly sized magnetic or
manual starter (both with properly sized heaters) be used
with all three phase motors. Install starters following instruc-
tions of the starter manufacturer. See Motor Rotation under
Operation Section for changing rotation on three phase
motors.
All motors (single and three phase) should be equipped
with a correctly fused disconnect switch to provide protec-
tion. Consult local or United States National Electric Codes
for proper fuse protection based on motor data chart (See
Charts C, D and Wire chart F).
This reading insures that there is an ample supply of water
into the pump inlet housing.

bling, reapply thread sealer.
PUMP DISASSEMBLY
To disassemble the pump, refer to the exploded parts view,
Figures 17 & 18 Tools Required
• Block of wood (2” x 4” x 12”)
Piece of 3/4” pipe (12” to 24” long)
• Pipe wrench
• Strap wrench
• 1/4” Dowel rod (about 24” long)
• 9/16” Open end wrench
• 3/8” Open end wrench
1. To stabilize pump during disassembly, place block of wood
underneath pump barrel.
2. Thread pipe into pump inlet port. This acts as a handle.
3. Using the pipe wrench, remove the discharge head, turn-
ing CCW (counter clockwise).
4. With the strap wrench, loosen the barrel, turning CCW
(counter clockwise). DO NOT use pipe wrench on pump
barrel.
Operation (Continued)
MOTOR/PUMP ROTATION
1. Single phase models are one (1) rotation only (counter-
clockwise when facing the pump end) and cannot be
reversed.
2. Proper rotation of pump impeller is critical for three phase
pumps. Pump motor should turn counterclockwise (CCW)
when facing pump end. Momentarily “bump” (apply
power for less than a second) the motor to check for
proper rotation. To change rotation on three phase units,
interchange any two (2) incoming line (power) leads.
Do not go over recommended maximum
operating pressure (see Specifications), while maintaining
minimum flow of 1.5 GPM thru the pump. Do not restrict
the inlet line to the pump.
If driver (electric motor) is overloaded, a valve can be
installed in the discharge line to increase the back pressure
and reduce driver loading.
5. Holding the impeller stack in place, position pump in
upright position, standing unit on the motor end cover.
6. Use the 1/4” dowel rod to hold the stages down and in
place on the pump shaft. Remove pump barrel.
7. Slide the stages off the pump shaft onto the 1/4” dowel
rod. Leave stages on rod and carefully set aside.
NOTE: There may be some small .010” shim washers located
next to the pump shaft coupling. Keep these shims for re-
assembly.
START - UP PROCEDURE
Once the preceding instructions have been completed, the
pump can be started.
1. During the first few hours of operation, inspect the pump,
piping and any auxiliary equipment used in connection
with the unit.
2. Check for leaks, excessive vibration or unusual noises.
8. Through the side opening of the mounting frame, hold
the motor shaft with 9/16” wrench. Remove the shaft and
coupling from the motor using the 3/8” wrench on the hex
shaped pump shaft.
NOTE: If the hex shaft comes free, leaving the coupling
attached to the motor, use vise grips to free the coupling.
MECHANICAL SEAL REPLACEMENT
1. Follow instructions under “Pump Disassembly”.
2. Remove the mechanical seal assembly.
a. The rotary portion of the seal assembly (carbon ring,
Buna-N gasket and spring will slide easily off the end of
shaft).
IL0539
Figure 12 - Correct Motor/Pump Rotation (all units)
NOTE: See rotation arrow on inlet casting.
b. Using two (2) screwdrivers, pry the ceramic seal and rub-
ber gasket from the recess of the mounting ring (See
Figure 14).
Maintenance
Disconnect power supply and depressur-
ize system before servicing pump or removing any compo-
nent.
The precision lapped faces of the mechan-
ical seal are easily damaged. Handle the replacement seal
carefully. Short seal life will result if seal faces (ceramic &
carbon) are nicked, scratched or dirty.
3. Clean the seal cavity of the mounting ring and the motor
thoroughly.
ROUTINE
Pump should be checked routinely for proper operation.
Replace or clean all filters and line strainers on a regular
basis.
4. Wet outer edge of rubber cup on ceramic seat with liquid
soap solution. Use sparingly (one drop only).
DRAINING
This pump cannot be completely drained because of internal
design. Most of the liquid can be drained by tilting the dis-
charge forward after removing discharge casting; or, the liq-
uid can be drained through the inlet port. Store in heated
areas.
CLEANING
If used for spraying insecticides, pump should be thoroughly
flushed with clean water after using.
LUBRICATION
The motor has prelubricated bearings. No lubrication is
required.
SERVICING THREE-PHASE UNITS
Loctite (thread sealer) is used on the threads between the
motor shaft and the pump shaft coupling. When reassem-

2. Remove cap screws that connect the motor to the
mounting ring and pull motor away.
3. Replace motor with standard Nema 56J jet pump motor
by positioning motor against the mounting frame and
assembling with four (4) cap screws.
IMPORTANT: Because damage to the shaft seal can occur in
disassembly, a new seal will be necessary.
PUMP REASSEMBLY
Before reassembling the pump, carefully inspect the com-
ponent parts of the cartridge (stage) assembly, looking for
damage, wear or heat distortion. Pay careful attention to
spacing direction of components, and location of shims.
Refer to Figure 16 for proper facing and parts arrangement.
If damage to Stage components is evident, a complete car-
tridge assembly or individual stage assemblies are available
for replacement (See Replacement Parts List).
1. Reassembly should follow the reverse order of the disas-
sembly procedure with special care given to replacement
of the rotary seal.
Maintenance (Continued)
NOTE: Liquid soap solution - one drop of liquid soap com-
bined with one teaspoonful of water.
5. With thumb pressure, press ceramic seal half firmly and
squarely into seal cavity. Polished face of ceramic seat
is up. If seal will not seat correctly, remove, placing seal
face up on bench. Reclean cavity. Seal should now seat
correctly (See Figure 14).
6. If seal does not seat correctly after recleaning cavity,
place a cardboard washer over polished seal face and
carefully press into place using a piece of standard clean
3/4” pipe as a press (See Figure 15).
IMPORTANT: Do not scratch seal face.
7. Dispose of cardboard washer and recheck seal face to
be sure it is free of dirt, foreign particles, scratches and
grease.
8. Inspect shaft to be sure it is free of nicks and scratches.
9. Apply liquid soap solution sparingly (one drop is suffi-
cient) to inside diameter of rubber rotating member.
10. Slide rotating seal member (carbon face down toward
ceramic face) and spring over the shaft.
IMPORTANT: Do not nick or scratch carbon face of seal
when handling.
MOTOR REPLACEMENT
The motor can be replaced with any standard Nema 56J jet
pump motor (of proper HP for each pump) by referring to
the following instructions.
1. Follow steps as outlined under Rotary Seal Replacement
and Pump Disassembly.
2. Check top and bottom of o-rings for damage. It is recom-
mended that new o-rings be used.
3. Do not use pipe compound of Teflon tape on barrel
threads. The o-rings will prevent pump from leaking.
4. After pump is reassembled, tighten the discharge head to
a torque of 45-50 ft/lbs. If torque wrench is not available,
tighten firmly but avoid distortion or damage to plastic
internal parts.
5. After reassembly, apply power momentarily to unit (15 to
30 seconds). The pump and motor should rotate freely or
with a light rubbing.
