Danfoss A/S Dual pressure switches Type KP

Danfoss dual pressure switch type KP 44 is designed for use as a pump guard to control and protect supply water pumps. It combines the functions of a pressure switch and a flow monitoring device.

The lefthand pressure bellows control the pump pressure. The righthand bellows cut out the pump if the suction pressure is too low. In this way the pump is protected from running dry and consequent bearing damage.
