12V RV Water Pump, 6 GPM, 70 PSI, Self-Priming

12V RV water pump delivers on-demand water pressure and fast flow for showers, faucets, and washdowns without constant cycling. This 4-chamber self-priming diaphragm design reaches up to 6 GPM (22.7 L/min) and 70 PSI, helping you pull from tanks and lines more easily, even after storage. Built for RV, caravan, marine, and yacht systems, it pairs a copper motor with vibration control for quieter operation and steadier output.
