Diaphragm pumps are controlled by a pressure switch and provide boat, caravan, and mobile home owners with a fresh water system that is as easy to use as their domestic water supply – with the versatility to offer flow or a trickle.
The switch senses the pressure drop when a tap is opened and activates the pump; it turns off when the system pressure builds to a pre-set limit as the tap is closed.
