The Seaflo 55 Series 12V DC Heavy Duty Diaphragm Pump is a high capacity automatic demand pump designed for water supply, agricultural spraying, and fluid transfer applications. Featuring a large five chamber diaphragm design with integrated pulsation dampening bypass, the pump delivers smooth high volume performance while reducing pump cycling, noise, and system vibration.
Available in flow capacities up to 18.9 litres per minute with pressures up to 60 PSI, the 55 Series is suitable for multi outlet systems without the need for an accumulator tank. 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, starting and stopping the pump when water flow is required.
Built with chemical resistant Viton valves and Santoprene diaphragm materials, the pump offers strong durability and long service life. The heavy duty motor delivers reliable performance with low current draw, while standard 1/2" NPT ports allow simple installation across a wide range of applications including agricultural systems, marine setups, recreational vehicles, remote cabins, and industrial water systems.
