INSTALLATION & OPERATION
INSTALLATION
This pump is designed to boost water pressure to create a high
pressure stream. 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".
Maximum inlet pressure is 80 PSI. Maximum discharge pressure
is 315 PSI. Warranty is void if these pressure limits are exceeded.
DISCHARGE PRESSURES
Consult the following table for acceptable discharge pressures.
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.

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.
