Pressure controlled diaphragm pumps provide boat owners with a fresh water system that
is as easy to use as their domestic water supply with the versatility to offer full flow or a trickle. The pump is controlled by a switch which senses the pressure drop when a faucet is opened and activates the pump, it turns off when the system pressure builds to a pre-set limit as the faucet is closed. This system allows any type of faucet or shower valve to be fitted, from 3/8" (10mm) bore for minimum water use to 1/2" (13mm) bore for maximum flow. Choosing the pump for your needs is simple just check your system size and the number of outlets you need to operate simultaneously and select the appropriate pump. Diaphragm pumps are self-priming, quiet in operation and can run dry for extended periods. It is always best to turn the pump off and then open a tap to
de-pressurize the system when you are not using the boat, as this will prolong pump life.
