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.
