Zoeller ZOEL-53-0003 Effluent Pump 0.3 Hp 230V Automatic

Product Description

The ZOELLER ZOEL-53-0003 is a submersible effluent and dewatering pump rated at 0.3 HP, 230 volts, single phase, drawing 4.8 amps. Built on the Model D53 Mighty-Mate platform, it delivers up to 43 GPM flow at a maximum head of 19.25 feet. The discharge is a 1-1/2 inch NPT connection. A 9-foot power cord and automatic float switch are included, making this a ready-to-install unit. The pump body is cast iron with a powder-coated epoxy finish that resists corrosion and aids motor heat dissipation. Licensed plumbers and pump service technicians typically install this unit in residential or light commercial wet-pit applications.

This pump is suited for residential and light commercial dewatering, groundwater transfer, and effluent handling. Typical installations include septic system effluent sumps, crawl space dewatering pits, and construction site water removal. The automatic float switch activates and deactivates the pump based on water level, reducing the need for manual monitoring. Each unit is pressure-tested, submerged, and run at the factory before shipment, confirming hydraulic and electrical integrity prior to field installation.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Disconnect and lock out all electrical power before servicing or repositioning the pump. Confirm the sump basin diameter and discharge line sizing are compatible with the 1-1/2 inch NPT outlet before installation. Do not run the pump dry, as the motor relies on submersion for cooling.
