Model 4405 Sewage Pump

Product Details

The Zoeller Model 4405 is part of the Waste‑Mate® 400‑series submersible sewage pumps, designed for high‑flow sewage handling, 3″ solids passage, and demanding commercial or residential wastewater applications. Its vortex impeller design allows debris‑laden wastewater to move freely through the pump without clogging, making it ideal for raw sewage, lift stations, and other solid‑heavy environments. With the ability to reach 38 feet of head and 361 GPM.

Engineered with a durable cast‑iron motor housing and pump housing, the Model 4405 is built for long service life in corrosive sewage conditions. Its oil‑filled motor provides superior heat dissipation, enabling the pump to maintain optimal operating temperature during extended operation or high‑demand cycles.

The 4405 is available in both automatic and nonautomatic versions, offering installation flexibility across simplex and duplex sewage systems. Automatic models include a dependable built in wide angle float, while nonautomatic units integrate easily with external floats or panel‑based controls—ideal for engineered wastewater systems.

For environments requiring additional motor protection, the Model 4405 is offered in double‑seal configurations, adding an upper mechanical seal that acts as a secondary safeguard against seal failure.

Every Model 4405 undergoes a complete submerged factory test, verifying hydraulic performance, shutoff head, flow rates, sealing integrity, and electrical function. This ensures that every unit performs exactly to specification upon installation, delivering the long‑term reliability associated with Zoeller’s Waste‑Mate® series.
