The Camco RV/Marine Variable Flow Automatic Demand Diaphragm Water Pump is a compact, heavy-duty 12V DC pump designed to deliver consistent water flow and pressure to multiple outlets simultaneously. With a 3.0 GPM flow rate and a 55 PSI automatic cutoff, this pump is ideal for RVs, boats, campers, and marine applications where space is limited but performance matters.
Featuring variable flow technology with an internal bypass, the pump reduces cycling for quieter, smoother operation. It is self-priming up to 6 vertical feet and can safely run dry without damage, making it reliable for both on-demand and continuous use. Rubber mounting feet help minimize vibration and noise, while the included mesh strainer and hose adapters simplify installation.
Compatible with both fresh and saltwater systems, this pump is built to perform in demanding mobile environments.
