Waste-Mate 4/10 HP Sewage Pump

The Zoeller M264 is a submersible sewage pump designed for residential and light commercial waste removal. It handles solids up to two inches in diameter and operates automatically via an integral vertical float switch. This unit is built for continuous duty in sewage ejector or dewatering applications requiring reliable solids handling.

115V Hermetically-Sealed Motor

The pump uses a 4/10 horsepower, single-phase motor rated at 115 volts AC and 9.40 amps. The motor is hermetically sealed and oil-filled with a permanent split capacitor design for consistent starting torque. This electrical configuration decides whether the pump matches the available power supply and circuit protection on site.

Vertical Float Switch Installation

The integral vertical float switch activates at 12 1/2 inches and deactivates at 4 1/2 inches, requiring a minimum sump pit diameter of 18 inches. Installers must ensure the pit depth accommodates the on/off levels and that the discharge piping supports the 2-inch solids passage. A restricted pit diameter or incorrect wiring of the integral switch are the most common installation errors.
