Water Pressure Managers

Having problems with variable water pressure at home? Calect can provide you with a solution. The all-in-one Grundfos Pressure Manager is the intelligent waterworks that controls your pump according to consumption in domestic water supply and booster systems.

PM 1 – BASIC FLEXIBILITY

PM1 Water Pressure ManagerPM1 is suitable for applications where start/stop of the pump according to consumption is needed. It is the basic flexibility solution offering start at 1.5 or 2.2 bar.

PM1 starts the pump when reaching the starting pressure and keeps running as long as there is flow.

PM1 offers dry-running protection and cycling alarm for increased safety in addition to the usual Grundfos quality, which guarantees high flexibility, robust electronics, and long life.

PM 2 – ALL-ROUND CONTROL

PM2 Water Pressure ManagerPM2 is the all-round control solution offering adjustable start at 1.5 – 5 bar. This enables customisation to different types of installations and desired comfort level. The start pressure is set inside the unit, whereas current pressure is read on the intuitive LED display on the front of the Pressure Manager.

PM2 starts the pump when reaching the starting pressure and keeps running as long as there is flow.

PM2 is equipped with an internal pressure tank to minimise starts and stops in case of leakage in the installation.

In addition, PM2 can be optimised for operation with large external pressure tank by enabling the 1 bar differential pressure functionality. This significantly reduces the number of operating hours of the pump in installations with pressure tank.
