40 PSI Pressure Switch & Seal Kit

Don't get caught out. Always carry a spare 40 PSI pressure switch and seals just in case! Suits FL40, FL44 and FL43 water pumps.

Failure of an Escaping Outdoors caravan style DC diaphragm water pump can usually be attributed to the pressure switch. Designed to regulate the delivery pressure, the pressure switch works by turning the pump off when the set pressure is reached, and turns the water pump back on again if the pressure drops.

If your pressure switch fails after a short time (less than 12 months) this can be an indication that the pump set up needs refining and probably requires an accumulator tank (pressure tank) in the system. Please call for assistance with your set up. Do check that this switch matches your pressure switch which you are replacing.

Pressure switch and seal kits available in this range are - 17 PSI, 35 PSI, 40 PSI, 60 PSI and 100PSI.
