Shurflo Water Pressure Pump 4009 Revolution Caravan Motorhome

Shurflo Water Pressure Pump 4009

The Shurflo Water Pressure Pump 4009 is suitable for caravans, motorhomes, and buses. It can be mounted in any position and operates quietly while supporting high flow rates.

This automatic 12V freshwater demand pump features a four-chamber diaphragm and internal bypass to provide consistent flow, reduce noise, and minimise cycling. It activates when system pressure drops and shuts off at 45 psi (3.1 bar). The pump is thermally protected, dry-run safe, and can be installed in any orientation.

It is a direct replacement for the Shurflo Series 2088 pumps. This listing includes the pump only; inlet filters and fittings are sold separately.
