Reliable on-demand water pressure for caravans, boats, and off-grid living
The Seaflo 33 Series Automatic Diaphragm Water Pump delivers a flow rate of 11.3LPM and a shut-off pressure of 45PSI, providing dependable water pressure for multiple taps, sinks, and showers. Designed for 12V DC systems, it is ideal for caravans, motorhomes, boats, and other mobile or off-grid water applications.
A built-in automatic pressure switch starts the pump when a tap is opened and shuts it off when water flow stops, delivering convenient on-demand operation. The 3-chamber diaphragm design is self-priming up to 1.8m, allowing flexible installation above or below the water tank.
Built for long-term reliability, the pump features a corrosion-resistant Santoprene diaphragm, durable EPDM valves, and run-dry protection to help prevent damage when operating without water. A semi-rigid rubber mounting base helps reduce vibration and noise for quieter operation.
