1/2 HP Submersible Sump Pump

The Dayton 3BB69 is a 1/2 HP submersible sump pump rated for 120V AC at 60 Hz. It uses a tether float switch with piggyback electrical connection for automatic operation. Cast iron construction covers the body and impeller, while a carbon ceramic shaft seal protects the motor. The unit draws 6.8 amps during operation.

Suited for residential sump pits needing automatic

Homeowners with standard sump basins who want automatic level control will find this pump suitable. The tether float requires enough pit width to swing freely without snagging on walls or piping. Installations needing a fixed vertical float or electronic sensor should look at a different switch design. Buyers needing higher flow at greater lift heights will need a larger horsepower unit.

Flow rate at 10 ft head is 57 gpm

This single figure shows whether the pump can keep up with incoming water at typical discharge heights. At 10 ft of head the pump moves 57 gallons per minute, dropping to 45 gpm at 15 ft and 30 gpm at 20 ft. Maximum shut-off head reaches 30 ft. Match this curve against your basin inflow and vertical lift to confirm adequate capacity.
