SJE AmpMaster®

Mechanically-Activated, Wide-Angle Pump Switch

Pump switches provide automatic pump control.

The 20 amp rated SJE AmpMaster® pump switch is designed to directly control grinder and high head sewage pumps up to 1 1/2 HP at 125 VAC and 3 HP at 250 VAC in grinder and lift station applications, as well as septic tank effluent pump (STEP) systems.

The SJE AmpMaster® pump switch is not sensitive to rotation or turbulence, allowing it to be used in both calm and turbulent applications.  It is available for pump down applications only.
