This listing is for the Escaping Outdoors 40 PSI water pump pressure switch and seal kit to suit the Escaping Outdoors FL40, FL44, FL40C, and FL43 DC electric diaphragm water pumps. This 40 PSI pressure switch and seal kit will also suit similar 12v diaphragm water pump brands ProPump, FloPump, Singflo and Sailfo.

Failure of a 12v caravan style diaphragm water pump can usually be attributed to the pressure switch. Designed to regulate the delivery pressure, the pressure switch works by turnign the water pump off when the set pressure is reached, and turns the pump back on again if the pressure drops.

If your pressure switch fails after a short time the most likely cause is an inbalance of pressure in the pump system which results in excess tork on the water pump motor. Pressure switch failure will stop the pump operating and protect the water pump from further damage to the motor or diaphragm. If you feel you are going through too many pressure switches it is an indication your set up needs refining and you most likely need to add an accumulator tank. Refinement will depend on the application.

Please phone or contact us if you require technical help with your water pump set-up.
