Serfilco "E" Pump

The rugged Series 'E' sump pump is a tough, all machined pump designed for years of trouble-free operation. This pump features a cantilevered, sleeved SS shaft which eliminates bearings and seals, resulting in a pump that can run dry without damage. A vapor seal between the rotating shaft and the support column protects the motor. The compound impeller prevents liquid from rising in the column, even at maximum TDH, while the semi-enclosed bottom impeller provides efficient flow performance at low horsepower. A unique characteristic of the Series 'E' pump is its ability to perform on continuous duty as a level control when an optional suction extension pipe is installed. With the motor energized, the pump will self-prime when liquid is above impeller level. The solution level will then be pumped down to the end of the suction extension, the pump will lose prime, then reprime when liquid again reaches the impeller. Discharge pipe assembly, suction extension and suction strainer are available options.
