The Series 'EH' Sump Pump features a cantilevered, sleeved, SS shaft with vapor seal between the rotating shaft and the support column to further protect the motor. The cantilevered shaft eliminates bearings and conventional pump seals, resulting in a pump that can run dry without damage. A compound impeller prevents liquid from rising in the column, even at maximum TDH, while the fully-enclosed bottom impeller provides high hydraulic efficiency at low horsepower.
A unique characteristic of all Series 'EH' pumps is their ability to lift solution with an optional suction extension pipe installed. With the motor energized, the pump will self-prime when liquid is at impeller level. The solution level will then be pumped down to the end of the suction extension to a maximum depth of 9 ft. (2.7m). The pump will lose prime, then automatically re-prime when liquid again reaches the impeller.
The standard 12" x 15" (305 x 381 mm) mounting plate for CPVC, PP and ECTFE-T pumps is shown. PVDF pumps have an 11-3/4" x 11-3/4" (298 x 298 mm) mounting plate.
