Pressure Booster Pumps
Description
Pressure booster pumps increase water pressure from city mains or private water
systems. 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.
Single-phase models are equipped with a capacitor start, thermal protected motor.
Three-phase models require separate overload protection.

Unpacking
When unpacking the unit, inspect
carefully for any damage that may
have occurred during transit.
‡ Equipped with carrying handle. 132079 handle available as an option for other models.
† Example: If PB0508A031 pump is connected to supply line of sufficient capacity, carrying water at 40 PSI, and the output of the pump is held to 7.3 GPM by a gate
valve, the pump will add 40 PSI to line pressure for a total output pressure of 80 PSI.
* Operation of pump in this range may result in reduced pump life and/or motor damage.
To keep pump and seal lubricated, a minimum flow of 1.5 GPM must always be maintained through the pump.

Carefully read and follow all safety instructions in this
manual and on pump. Keep safety labels in good condition.
Replace missing or damaged safety labels.
This is a SAFETY ALERT SYMBOL. When you see this
symbol on the pump or in the manual, look for one
of the following signal words and be alert to the
potential for personal injury or property damage.
Warns of hazards that WILL cause serious
personal injury, death or major property
damage if ignored.
Warns of hazards that CAN cause serious
personal injury or death, if ignored.
Warns of hazards that MAY cause minor
personal injury, product or property damage
if ignored.
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.
9. Do not insert finger or any object into pump or motor
openings.
10. Secure the discharge line before starting the pump. An
unsecured discharge line will whip, possibly causing
personal injury and/or property damage or puncture.
Do not touch an operating motor or
engine. They are designed to operate at
high temperatures.
This product contains chemicals known
to the State of California to cause cancer
and birth defects or other reproductive
harm.
Risk of Electric Shock. This pump has not
been investigated for use in swimming
pool areas.
NOTE: Pumps with the “CSA-CUS” mark are tested to UL
standard UL778 and certified to CSA standard C22.2 No. 108.
Pre-Installation
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
In any installation where property
damage and/or personal injury might
result from an inoperative or leaking
pump due to power outages, discharge line blockage, or any
other reason, a backup system(s) should be used.
1. Locate pump as close to the fluid source as possible,
keeping 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.
Hazardous voltage. Can shock,
burn or cause
death. Ground
pump before connecting to power
supply.
Wire motor for correct voltage. See
“Electrical” section and Motor Data Charts
C&D of this manual, and motor nameplate.
Ground motor before connecting to
power supply.
Meet United States National Electrical
Code and local codes for all wiring.
Do not handle a pump or pump motor
with wet hands or when standing on a wet
or damp surface or in water.
3. Mount unit in a dry location that is easily accessible for
Follow wiring instructions in this manual when connecting
to power lines.
Always disconnect power source before
performing any work on or near the motor
or its connected load.
Do not use to pump flammable or explosive fluids such
as gasoline, fuel oil, kerosene, etc. Do not use in flammable and/or explosive atmospheres.
inspection and maintenance. If a dry location is not
available, mount it on a foundation well above the wet
floor.
4. Allow ample clearance around unit for free air
circulation.
SUCTION LIMITATIONS
1. Units are non self-priming.
Hazardous pressure! Install pressure relief valve in
discharge pipe. Release all pressure on system before
working on any component.
2. Pressure booster pumps are not recommended for
suction lift applications.
PIPING
1. Use galvanized piping, rigid plastic or other suitable pipe
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. Keep work area clean, uncluttered and properly lighted;
replace all unused tools and equipment.
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.
that will not collapse under suction or rupture due to
pressure.
If hose is used, make sure it is the
reinforced 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.
4. Use pipe compound on all joints and connections. Use
Teflon tape or plastic joint stik, on plastic pipe. Draw all
pipe up tightly.
be air and water tight for efficient/
proper operation.
Installation
PUMP INSTALLATION
IMPORTANT: Pump is built to handle
clear water only; it is not designed to
handle water containing sand, silt or
other abrasives.
1. Refer to Figures 6, 7, and 8 for
typical installations.
Support pump and
piping when assembling and when
installed. Failure to do so may cause
piping to break, pump to fail, motor
bearing failures, etc.
2. If the pump is used as part of a
permanent installation, bolt to a
rigid foundation.
Use only
components that
are rated for
maximum pressure pump can produce
when used in boosting system or any
other system. Do not exceed the total
maximum pressure boost as listed per
model in Performance Charts B.
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.
Do not use a globe
valve or other
restricting type of
valve that will seriously restrict the
pumps discharge capacity.
3. Install a check valve as shown in
Figure 6. Be sure check valve flow
arrows point in the direction of
water flow.
4. Whenever dirt, sand or debris is
present in the supply water, install
a strainer or filter on the inlet side
of the pump (See Figure 7).
NOTE: For heavy amounts of
sediment, install a trap filter on the
inlet side of the pump (See Figure 5).
NOTE: Pressure gauges installed
before and after the filter will show
pressure differential indicating
the need for filter replacement or
cleaning.
