The SEAFLO 53 Series DC Diaphragm Pump is built for high-demand RV, marine, agricultural, and pressurized water systems that require strong flow, dependable pressure, and rugged long-term performance. With 7.0 GPM open flow, 60 PSI shut-off pressure, and a heavy-duty 24V motor, this pump delivers the volume needed for larger water systems and multiple fixtures. Engineered with a five-chamber diaphragm, the 53 Series provides smoother high-volume water flow with reduced pump cycling. The pump is self-priming up to 6 feet, safe for normal run-dry operation, and designed with semi-rigid rubber feet to reduce vibration and operating noise. The uploaded SEAFLO manual also confirms key 53 Series features including continuous duty, self-priming operation, run-dry capability, bypass cycling reduction, and automatic pressure switch operation. Designed for easier installation and service, this automatic demand water pump uses quick attach port fittings and starts or stops as fixtures open and close. Built with EPDM valves, a Santoprene diaphragm, and durable heavy-duty construction, the SEAFLO 53 Series is a dependable choice for RV water systems, marine freshwater systems, washdown setups, and demanding utility applications.
