12V Self Priming Electric Water Pump for RV

The 12V self-priming diaphragm water pump delivers consistent water movement directly from any standard 12-volt battery or converter without requiring submersion. Built with a polypropylene housing and pure copper motor, this compact unit achieves up to 5.5 liters per minute while reaching a maximum working pressure of 0.85 MPa (123 PSI). The integrated pressure switch automatically powers down the motor once that threshold is reached, then instantly restarts when demand lowers.

Mounting flexibility makes this pump ideal for recreational trailers, boat freshwater systems, or portable cleaning rigs. The left inlet and right outlet connect directly to eight-millimeter tubing using the included clamps, allowing safe overhead placement above your reservoir thanks to the anti-backflow design. Wires attach directly to power sources with full polarity tolerance, and the strict dry-install requirement ensures reliable operation across continuous irrigation or vehicle washing cycles.
