Zoeller 137-0050 Effluent Pump, 1/2 HP, 460V 3-Phase

Engineered for reliable performance in residential and light commercial applications, the Zoeller 137-0050 Effluent Pump delivers powerful 1/2 HP operation at 460 volts with 3-phase power. This heavy-duty cast iron submersible pump is ideal for septic systems, low pressure pipe (LPP) systems, and enhanced flow STEP systems, handling groundwater and effluent transfer with ease.

Built to last, the pump features a fully cast iron construction—including the motor, housing, base, and impeller—ensuring durability and resistance to corrosion. Stainless steel components, carbon-ceramic shaft seals, and a powder-coated epoxy finish further enhance longevity, while the oil-bath sleeve bearings and absence of clog-prone screens minimize maintenance. Rated for effluent temperatures up to 130°F (54°C) with extra-duty capability up to 140°F (60°C), this pump passes spherical solids up to 5/8" and includes a 15 ft. cord for flexible installation.
