High-Flow 12V Diaphragm Pump

The VEVOR 12V diaphragm pump delivers 3.0 GPM at 55 PSI for RVs, yachts, food trucks, campers and marine installations. Its four-chamber design provides steady pressure for daily water demand. The on-demand pressure switch activates automatically when a faucet opens and stops when closed, removing the need for manual control.

Adjustable Pressure Switch and Quiet Build

The pressure switch adjusts from 40 to 100 PSI and is tested over 200000 cycles for durability. A pure copper motor, plastic pump body and noise-reducing base keep operation quiet. CE and ROHS certification plus overheat and overload protection add safety. The 1/2'' MNPT ports accept standard fittings and a filter is included.

Upgrade from Low-Pressure or Single-Chamber Pumps

This unit replaces pumps that cannot maintain consistent flow at multiple outlets or that cycle noisily. The jump is worth it when you need reliable 55 PSI performance with automatic on-demand control and quiet running in mobile or off-grid setups. Buyers needing higher flow rates or different voltage requirements should look elsewhere.
