3/10 HP Submersible Sump Pump

The Zoeller 63-0001 is a 3/10 horsepower submersible sump pump designed for residential water removal. It operates on 115V AC single-phase power at 60 Hz, drawing 9.7 amps. A cast iron body and impeller provide structural durability for continuous immersion. The unit activates via an integral vertical float switch.

Sustained Operation and Flow Rates

Under continuous load the pump delivers 43 gallons per minute at 5 feet of head, 34 gallons per minute at 10 feet, and 19 gallons per minute at 15 feet. Maximum shut-off head reaches 19 feet. The Buna-N, carbon, ceramic and stainless steel shaft seal maintains sealing integrity during extended run cycles. The float switch turns the pump on at 7 1/4 inches and off at 3 inches.

18-Inch Minimum Sump Pit Diameter

This pump requires a sump pit with a minimum diameter of 18 inches to accommodate the 7 7/8-inch body diameter and float switch travel. Installations with smaller pits will restrict switch movement and prevent automatic operation. Buyers with existing pits below this dimension cannot use this model without excavation. The discharge outlet is 1-1/2 inches female.
