1/2 HP Cast Iron Submersible Sewage Pump | Heavy-Duty Waste Water & Sump Pump Q1DZ450X

Q1DZ-450X 1/2 HP Cast Iron Submersible Sewage Pump

Heavy-Duty Wastewater Management for Residential and Light Commercial Systems

Rugged Cast-Iron Construction

Engineered for demanding below-grade installations, this premium submersible pump features a highly durable cast-iron housing designed to withstand harsh environments and resist long-term corrosion. It is the ideal, heavy-duty solution for reliable basement drainage, septic tank effluent pumping, and managing complex sewage systems.

High-Efficiency Solid Handling

Powered by a robust 1/2 HP (3450 RPM) permanent split-capacitor motor, the pump delivers an impressive maximum flow rate of 4300 GPH. With a maximum head lift of 20 ft (6 m), it utilizes an advanced thermoplastic vortex impeller to significantly reduce clogging risks while efficiently processing wastewater and suspended sewage solids.

Reliable Automated Operation

Built for continuous, hands-free performance, the system includes a replaceable piggyback tether float switch for dependable automatic operation. The fully oil-filled motor maximizes heat dissipation to extend the unit's service life, while built-in thermal overload protection automatically shuts the system down to prevent overheating during rigorous use.

Versatile & Ready to Install

Designed for seamless integration into your existing plumbing infrastructure, the pump features a standard 2" NPT discharge port. It also comes equipped with a highly durable 10 ft (3 m) SJTW power cord, providing flexibility and ease of installation in deep sump pits and drainage basins.
