1 HP 240 V Effluent Pump

The Dayton 4HU77 is a single-phase effluent pump rated at 1 horsepower and 240 volts AC. It is built for residential or light-commercial wastewater systems that move screened effluent from a tank to a drain field or mound. The cast-iron body and nitrile-silicon carbide shaft seal suit continuous submerged operation.

8.3 A Motor Draw

The pump draws 8.3 amps at 60 Hz, which is the critical figure for sizing the branch circuit and selecting a compatible control panel. Verify that the electrical supply and any float-switch assembly match this amperage before installation.

Cast Iron Body With Polypropylene Impeller

The cast-iron housing resists corrosion in septic environments while the polypropylene impeller handles suspended solids typical of effluent. No switch is included, so a separate level control and discharge piping must be supplied to complete the system.
