E20 LOSS OF PRIME PRESSURE SWITCH

FeaturesE20 Pressure switch

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 E10 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.
