ELECTRICAL SAFETY
Some models of
pump are supplied
with 3-connector
grounding type cord.
Connect only to properly
grounded, GFCI protected
outlet. Do not lift pump by
electrical cord.
Pump is non-
submersible. Keep
motor dry at all times. Do
not wash motor. Do not
immerse. Protect motor
from wet weather.
If using extension
cord, use only UL
approved indoor/outdoor,
3-wire, grounding type cord. Do not allow any part
of cord or receptacle ends to sit in water or damp
locations.
Unplug pump before servicing.
Burn Hazard. Do not touch an oper-
ating motor. Modern motors are designed to operate at
high temperatures. To avoid burns when servicing
pump, allow it to cool for 20 minutes after shut-down
before handling.
Follow local and/or national plumbing and electrical
codes when installing.
Hazardous Pressure. DO NOT run the
pump with discharge shutoff, as hose may burst or
pump may be damaged due to high temperatures.
READ AND FOLLOW
SAFETY INSTRUCTIONS!
This is the safety alert symbol. When you see this
symbol on your pump or in this manual, look for one of
the following signal words and be alert to the potential
for personal injury:
DANGER warns about hazards that will cause serious
personal injury, death or major property damage if
ignored.
WARNING warns about hazards that can cause serious
personal injury, death or major property damage if
ignored.
CAUTION warns about hazards that will or can cause
minor personal injury or property damage if ignored.
The word NOTICE indicates special instructions which
are important but not related to hazards.
GENERAL SAFETY
To avoid risk of serious bodily injury and property
damage, read safety instructions carefully before
installing pump.
Do not allow pump or any system component to freeze.
To do so may damage system and will void warranty.
Risk of electric shock. To avoid fatal
shocks, proceed as follows if pump needs servicing.
A. Disconnect power to pump outlet box before pul-
ling pump cord plug. After plug is pulled, let pump
cool for 20 minutes before attempting to work on it.
B. Take extreme care when changing fuses. To re-
duced chance of fatal electrical shocks, DO NOT
stand in water or put your finger in the fuse socket.
C. Ground electrical outlet box.
D. Use only Ground Fault Circuit Interrupter (GFCI)
protected grounded outlet for cord plug.
Never run pump dry. Running pump dry can damage
internal parts, overheat pump (which can cause burns to
people handling or servicing pump), and will void
warranty.
Do not pump chemicals or corrosive liquids with pump.
Hazardous Pressure.
A. Use high pressure reinforced type discharge
hose ONLY. See parts list for available hose, nozzle
and fittings. A high pressure relief valve is recom-
mended.
B. DO NOT use garden hose with High Pressure
Booster pump. Garden hose will not stand the
discharge pressure produced and will fail.
C. High pressure discharge stream is dangerous. To
avoid injury, DO NOT aim the discharge stream at
any person or animal.
D. BE SURE that the pump suction pipe pressure
plus the pump discharge pressure does not
exceed the pressure rating of hose and fittings.
See Table I for pump discharge pressure ratings.

WARNING
Hazardous voltage.
Can shock, burn, or
cause death.
Ground pump before
connecting to power
supply.

INSPECT THE SHIPMENT
The high pressure booster pump has been carefully
inspected and packaged to assure safe delivery.
Inspect the pump and fittings and report to the carrier
any items which are damaged or missing.
INSTALLATION
The pump is designed to boost city water pressure or
water pressure from a private water system. Use this
high pressure stream to wash down milk parlors, barns,
garages and driveways, or for fire protection.
The pump is portable with a convenient carrying handle.
If an existing pressure water system is to be used as a
water supply, it can be connected with available fittings
and 3/4” or 1” high pressure hose to the pump inlet. A
special heavy duty 3/4” or 1” suction hose with fittings is
available as an accessory. If pump is permanently
mounted on wall, use a 3/4” or 1” pipe or heavy-duty
hose for suction line. 20 GPM models require one-inch
discharge hose to reduce friction losses and 30 GPM
models require 1-1/4”.
Hazardous pressure. Pump body may
explode if pressures exceed rated limits. Maximum
inlet pressure is 80 PSI. Maximum discharge pressure is
315 PSI. Warranty is void if these pressure limits are
exceeded.

TABLE I - DISCHARGE PRESSURE
*For total discharge pressure, add this pressure to suction pipe
pressure. For example, an HP7C pump taking suction from a 100
psi water service line will produce 130 + 100 = 230 psi total discharge
pressure at 0 GPM flow. If suction pressure drops to 50 psi,
discharge pressure will drop to 180 psi.
NOTE: Model numbers that include an “S” (HPS7C, HPS10D, etc)
have a stainless steel suction, discharge assembly, and capscrews.
Model numbers ending in “3” (HP7C3, HPS10C3, etc) have 3-phase
motors. Models numbers ending in “T” have TEFC motors.

To reduce friction losses to a minimum, inlet (suction)
line should be short and have as few elbows as
possible.
Size the inlet according to the chart below:
An inlet strainer will prevent suspended debris from
clogging pump.
The internal running surfaces of the pump and seals
require water lubrication for good, consistent operation.
Allowing pump to run dry will severely damage
pump and seals.
Install a pressure gauge in pump inlet line. Keep at
least two pounds per square inch pressure (2 PSI) in
inlet line whenever pump is operating. If this is not
possible, consult customer service representative.
LUBRICATION
It is not necessary to lubricate pump or motor. The
motor is equipped with sealed ball bearings, lubricated
for the life of the bearing. The mechanical shaft seal in
the pump is self-lubricating and requires no adjust-
ment. Disassemble pump to replace seal (See “Main-
tenance”, Pages 7 to 9).
OPERATION
NOTICE: Observe the following precautions when
operating the pump:
1. Keep the motor dry! Do not direct stream from
pump discharge onto the motor!
2. Hazardous pressure. Do not run the
pump with discharge shutoff, as hose may burst or
pump may be damaged due to high temperatures.
3. Do not use a standard trigger gun with this pump.
Use only trigger guns with an automatic weeping
feature. These are available as accessories and are
provided with three nozzles. The smallest nozzle
restricts the flow, allowing use of a smaller water
source. The two larger nozzles are used if the water
source will supply the pump’s full capacity.
4. Do not run pump dry; to do so may damage the
seal.
5. To avoid internal damage to pump, Do not operate
with water temperature above 175 degrees F.

To Check For Proper Rotation – 3 Phase Motors
Risk of electrical shock.
1. Be sure power is disconnected to motor when
working on electrical connections.
2. Remove the motor end cover, exposing motor shaft.
Momentarily start pump. If hookup is correct, the
shaft will rotate clockwise.
3. If rotation is not clockwise, reverse any two leads to
the starter. The rotation will now be correct.
GROUNDING THE MOTOR
Ground the pump permanently using a wire of size and
type specified by local or National Electrical Code.
Models (HP7C-01 and HP7D Series Only) with
factory installed cord and plug:
Risk of electric shock. This equipment is
only for use on 115V and is equipped with an approved
3-conductor cord and 3-prong, grounding-type plug. To
reduce the risk of electric shock, be certain that it is
connected to a properly grounded, grounding-type
receptacle. Do not modify or remove plug. Make sure
pump circuit meets National Electrical Code. To avoid
dangerous electrical shock hazard, keep cord dry at all
times.
Models without cord and plug:
1. Connect ground wire first. Connect the ground first,
then to green grounding terminal provided under
motor canopy (see Figures 5 and 6) identified as
GRD. Make ground connection to this terminal. Do
not connect motor to electrical power supply until
unit is permanently grounded; otherwise serious or
fatal electrical shock hazard may be caused.
2. For best ground connection, connect to a grounded
lead in the service panel or to a metal underground
water pipe or well casing at least 10 ft. long. If
plastic pipe or insulated fittings are used, run ground
wire directly to the metal well casing or use ground
electrode furnished by the power company.
