Johnson Pump Aqua Jet WPS 2.9 GPM 12V Water Pressure Pump, 2.8 Bar, NPT Ports

The Johnson Pump Aqua Jet WPS is a 12V DC water pressure pump built for onboard fresh water systems on boats and RVs. It delivers a maximum flow rate of 2.9 gallons per minute at up to 2.8 bar of pressure, giving consistent water delivery to sinks, showers, and washdown fittings even at the far end of a plumbing run. The pump can lift water up to 6.5 feet, making it suitable for tanks mounted below the point of use.

Its housing is molded from durable black plastic, keeping the unit lightweight while resisting the moisture and vibration typical of marine and RV installations. Water connections use NPT threaded ports, allowing it to be plumbed directly into standard NPT fittings and hose adapters without additional thread adapters. At 12V DC, it runs directly off a boat or RV battery bank, making it a straightforward addition or replacement for an existing onboard pressure water system.

The pump measures 10 inches by 10 inches by 12 inches and weighs 4.49375 pounds, sized to fit within typical under-sink or utility compartment mounting spaces.
