The SEALFLO 12V Self-Priming Diaphragm Water Pump delivers a powerful 55PSI (379kPa) maximum pressure and a flow rate of 11.3 litres per minute, making it one of the most capable 12-volt fresh water pumps available for mobile and off-grid installations. Built around a robust diaphragm pump design, it self-primes from dry in seconds and features an automatic pressure switch that turns the pump on when a tap is opened and shuts it off the moment flow stops — eliminating the need for a separate controller and protecting the motor from running dry. The pump runs quietly on any 12V DC source (10–14V operating range) and draws a maximum of 7.5A, keeping your battery draw well in check even when running multiple fixtures.

Whether you are kitting out a caravan, camper trailer, motorhome, boat, or off-road 4WD rig, this pump delivers consistent mains-like water pressure wherever your adventures take you across Australia. It is the go-to upgrade for grey nomads tired of trickle-flow pumps, weekend warriors setting up a camp shower off a jerry can, and marine enthusiasts needing reliable fresh water on board. The self-priming capability means it can pull water from tanks located below the pump — ideal for under-floor caravan tank setups common in Australian-built vans — and the corrosion-resistant materials ensure long-term durability in the harsh Australian climate.
