  • 1 HP motor delivers strong pumping power

1 HP Submersible Sump Pump 115V

The Zoeller 140-0029 is a 1 HP submersible sump pump rated for 115V AC at 60 Hz. It draws 12 A and features a cast iron body with a thermoplastic impeller. The carbon and ceramic shaft seal supports durability in continuous drainage applications.

Tether float switch with piggyback plug

This unit suits installations where a tether float can move freely in a pit of at least 18 in diameter. The piggyback electrical connection allows simple plug-in operation. Sites requiring a vertical float, a different voltage supply, or a smaller pit diameter should consider other options.

80 gpm flow at 10 ft head

At 10 ft of head the pump delivers 80 gpm, falling to 73 gpm at 15 ft and 66 gpm at 20 ft. Maximum head reaches 50 ft. The 20 ft cord length and 10 3/16 in body diameter determine placement flexibility.
