The FL-40 12V High Pressure Diaphragm Water Pump delivers reliable, on-demand water supply wherever the road takes you. Running on 12V DC power straight from your vehicle or auxiliary battery system, it produces up to 17 litres per minute at its pressure setting and a steady 10 LPM at peak demand — driven by a 40 PSI self-priming diaphragm mechanism that kicks in automatically when flow is required and shuts off when pressure is satisfied. The all-plastic engineering-grade housing keeps weight down and resists the corrosion that Australian coastal and outback conditions dish out, while the built-in pressure switch protects the pump and your plumbing from over-pressurisation.

Built for Australian caravanners, boaties, and 4WD tourers, the FL-40 earns its keep as a pressurised water source in caravan freshwater systems, camper trailer setups, boat livewells and washdown lines, and camp shower rigs. Whether you're rinsing saltwater off dive gear after a reef trip in Queensland, supplying a camp kitchen sink on a Kimberley station track, or pressurising a mobile wash station at a remote 4WD campsite, this compact pump handles the job without draining your battery bank. Its self-priming design means it can draw from a tank positioned up to 2 metres away, making installation in a van, trailer, or tinnie straightforward and flexible.
