ing pressure to 40 PSI. Reliable belt-driven diaphragm design allows pump to run dry without damage. A built-in check valve pro-
tects the pump against city water pressure. Pulsation Dampeners help to absorb "water hammer" and provide a steady flow of water.
Large mounting pads absorb vibration which reduces noise. INCLUDES ports for 1/2"-5/8" hose. May also be used for saltwater deck
wash-downs.
