Little Giant - 6EN Series (6EN-CIM, 6EN-CIA) - Sump Effluent Pumps

The Little Giant 6EN series pumps feature 1/3 HP permanent split capacitor (PSC) motors providing lower current draw, energy efficiency, improved performance and cooler-running for durability. Built on the industry's best 6E platform, the 1/3 HP 6EN series consumes only 6.0 amps while producing 50 gpm @ 5 ft of head and reaching a maximum shut off of 22 ft. The new unit also includes a stainless steel plate on the volute as a debris filter, creating lower intake velocities and pump stability.
