Description

The E20 loss of prime pressure switch is a solid-state digital pressure switch specifically for the control and protection of domestic and industrial pressure pumps and air compressors.

Pressure switches normally have two set points, a low pressure cut in point and a high pressure cut out point. A pump under the control of such a switch operates between the two set points. If pressure is lost due to the pump running dry or due to a burst pipe the pump will continue to run simply because the pressure switch remains on. In such a situation the pump will invariably sustain substantial damage due to being run dry. The E20 pressure switch addresses this problem by providing a third adjustable switch point that can be set below the normal operating range to turn the pump off and prevent it being damaged if it runs dry.
