12V RV Diaphragm Water Pump, 4 GPM, 40 PSI, Auto Switch

12V RV water pump delivers on-demand water flow for steady faucets, showers, and washdowns without constant cycling. This 3-chamber self-priming diaphragm design reaches up to 4 GPM (15.1 L/min) and 40 PSI to pull from distant tanks and keep pressure consistent. Built with a protective cover, heavy-duty power cord, and quick 1/2 in hose connections for faster installs in RVs, caravans, boats, and utility setups.

Set up a reliable on-demand water system for your RV, camper, caravan, marine, yacht, food truck, garden irrigation, or car washing. The adjustable pressure switch lets you fine-tune output with a hex wrench, while the included filter helps keep larger debris out of the pump. Install in a dry, protected area—this unit is not waterproof and isn’t intended for outdoor exposure. Grab yours today and upgrade your water pressure without the noise and hassle.
