Johnson Pump Aqua Jet WPS 3.5 GPM 12V Water Pressure Pump, Self-Priming Diaphragm Pump 10-13395-103

The Johnson Pump Aqua Jet WPS 3.5 is a 12 volt, self-priming diaphragm water pressure pump built to deliver quiet, pulsation-free water pressure on both small and medium sized leisure and commercial boats. Its five chamber diaphragm design smooths out flow so the pump runs quietly even at low speeds, making it well suited to onboard shower and galley applications where low amperage draw and low noise are priorities. The pump operates in either fresh or sea water and delivers up to 3.5 gallons per minute with a 41 psi pressure cut-off, powered by an 85 watt, 12 volt motor protected by a 10 amp fuse.

Construction pairs a PP/PPA (polypropylene) pump body with EPDM valves and a Santoprene diaphragm for durability against marine water exposure. The pump is self-priming, simplifying installation in fresh water and shower/galley plumbing runs. It is recommended to install the pump with an accumulator tank and to always use a PUM Protector inlet strainer ahead of the pump intake to protect the diaphragm and valves from debris. Connections are sized at 3/8 inch NPT or 1/2 inch hose, and 1/2 inch NPT or 3/4 inch hose, giving flexibility when adapting to existing plumbing.
