Pump Pressure Switch – Adjustable Pressure – PresSystem


Single phase pump controller which is installed on clean-water pipe work. By using a single speed, variable pressure control system, the PresSystem ensures pump efficiency by reducing the time a pump is run to maintain pressure in the system.
Dry Run Protection via either a Float Switch (not included) or built in CosPhi option.

SKU: PSP*. Categories: , .




For residential pressure boosting systems. Replaces traditional pressure boosting systems that use a pressure switch and a pressure vessel (expansion tank). Option for built in CosPhi Dry Run Protection. Alternatively both models can be used with a Float Switch after adjusting the housing.


Designed to be mounted directly on to the pipe work. The innovative built-in pressure sensor ensures flow is not obstructed through the unit.


On pipe mounting reduces the need for mounting surfaces and running pipes to a controller. As the PresSystem does not obstruct the pipe in any way, losses usually associated with pressure measurement do not arise.
