The Johnson Pump Aqua Jet WPS 4.0 water pressure pump (article number 66101340603) delivers pressurized fresh-water flow for small boats and RVs with a five-chamber design that reduces noise and water pulsations. It runs on 12V with a 100W motor, provides up to 15 l/min (4.0 GPM), and uses a pressure switch with a 2.8 bar cut-out. Durable materials—Santoprene diaphragm, EPDM valves, and a polypropylene housing—support long service life, while self-priming up to 2 m and dry-running capability help protect operation in real onboard conditions.
