The Seaflo 51 Series 12V DC Heavy Duty Diaphragm Pump is a high capacity positive displacement pump designed for demanding agricultural, industrial, and fluid transfer applications. Featuring a large five chamber diaphragm design, the pump delivers high flow performance while reducing pump cycling, providing smooth and reliable operation across a wide range of systems.
Delivering flow rates up to 11.5 litres per minute with pressures up to 60 PSI, the pump is ideal for spraying systems, water transfer, filtration setups, and mobile equipment where consistent flow and durability are required. The self priming design allows operation without manual priming and enables the pump to run dry without damage, improving reliability and operational flexibility. An integrated automatic pressure switch provides on demand operation, automatically starting and stopping the pump based on system requirements.
Built with Viton valves and Santoprene diaphragm materials, the pump offers strong chemical resistance and long service life. The robust motor delivers dependable performance with low current draw, while standard 1/2" NPT ports allow simple installation across a wide range of applications including agricultural sprayers, marine systems, recreational vehicles, and solar water systems.
