EC Pump

The Series 'EC' Sump 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 semienclosed bottom impeller provides efficient flow performance at low horsepower. A unique characteristic of all Series 'EC' pumps is their ability to perform on continuous duty as an automatic level control* when an optional suction extension pipe is installed. With the motor energized, the pump will self-prime when the liquid is at impeller level. The solution level will then be pumped down to the end of the suction extension, the pump will lose prime, then automatically re-prime when liquid again reaches the impeller. The pump casing can be rotated for choice of discharge direction and flexibility of installation. Discharge pipe assembly, suction extension and suction strainer are available options.
