12V Diaphragm Pump for Mobile Water Systems

This 12V diaphragm pump delivers 3.0 GPM at 50 PSI through a three-chamber design. An adjustable pressure switch operates between 40 and 100 PSI and activates automatically when a faucet opens. The unit includes a 1/2'' MNPT port, an inlet filter and a user manual. It is built for mobile installations that demand reliable on-demand water pressure.

Suited for RVs, Yachts, Food Trucks and Campers

Installers who need a compact, self-priming pump with automatic cycling will appreciate the 96W copper motor and noise-reducing base. The pump weighs 4.21 lbs and measures 8.15 x 5.43 x 4.92 in, fitting tight compartments. Buyers requiring AC power, higher flow rates or pressures above 100 PSI should consider a different solution.

3.0 GPM Flow with 50 PSI Continuous Pressure

The pump comfortably supplies multiple fixtures in a recreational vehicle or marine galley. At 3.0 GPM (11.36 L/min) it handles showers, sinks and appliance fill cycles without pressure drop. The adjustable switch tops out at 100 PSI, so systems demanding sustained pressure beyond that limit will exceed the pump's capability.

Questions about this item

What power source do I need to run the 12 V diaphragm pump?

The pump requires a DC 12 V supply capable of delivering 96 W; connect it directly to a 12 V battery or a regulated 12 V power source with adequate current capacity.

Will the 1/2'' MNPT ports fit the existing plumbing on my RV or boat?

The inlet and outlet are 1/2'' MNPT threads with a 20.955 mm outer diameter; they match standard RV and marine fittings, so you can thread them directly onto compatible hoses or adapters.

How can I verify the pump is operating correctly after installation?

Open a faucet and confirm the pump starts automatically, delivers a steady flow up to 3.0 GPM, and shuts off at the set pressure between 40 and 100 PSI without cycling when the tap is closed.
