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.

*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.
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.
