Goulds Water Technology PS51P1 Submersible Sewage Pump

Product Description

The GOULDS WATER TECHNOLOGY PS51P1 is an automatic submersible sewage pump in the PS Series, designed for residential and light commercial sewage ejection applications. Rated at 1/2 horsepower and operating on 115 volts AC at 60 Hz, this pump delivers a flow rate of up to 110 GPM with a maximum total dynamic head (TDH) of 23 feet. The cast iron construction provides durability in demanding wet-pit environments. A thermoplastic impeller and ball bearing motor round out the core design. Licensed plumbing contractors and pump service technicians are the typical installers for this class of sewage pump.

The PS51P1 is built for automatic operation in residential sewage ejector pits and lift stations where solids-laden wastewater must be pumped to a gravity sewer or septic system. The single-phase, 1/2 hp motor runs at 3400 RPM and draws 13 milliamps, making it suitable for standard residential electrical circuits. The 2-inch NPT discharge outlet connects directly to common sewage ejector piping configurations. The unit ships with a 10-foot SJTW 16/3 AWG cord for direct connection to a nearby junction box or control panel.

Key Features

Compatibility

Designed as an OEM-style replacement or new-installation pump for residential and light commercial sewage ejector pit systems requiring a 1/2 hp, 115-volt, single-phase automatic submersible pump with a 2-inch NPT discharge.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Disconnect and lock out all electrical power to the ejector pit before lowering or removing the pump. Ensure the discharge piping includes a check valve above the pump to prevent backflow. The pump must remain fully submerged during operation and should never be run dry.
