Serfilco, Ltd. Series 'EH' Vertical Pumps P-45-0655 T

Material: PP, CPVC, PVDF Performance: 20-175 gpm Features HIGH EFFICIENCY AND LOW ENERGY USAGE • Flows to 185gpm or 145ft. TDH @ 60 Hz • Non-metallic solution contact - PPP, CPVC, PVDF • Shaft vapor seal protects motor bearing and atmosphere • Runs dry • Chemical duty motor (1.0 - 7.5 HP) • Centrifugal - quiet, vibration-free • In or out-of-tank installation • Choice of 12" or 18" column • NPT or BSP connections Specifications 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.
