Description
Product Overview
The Zoeller M57 Mighty-Mate is a heavy‑duty submersible sump pump engineered for residential basement water management. Constructed from cast iron, the motor housing delivers exceptional durability and heat dissipation, while stainless steel hardware resists corrosion in wet environments. With a 0.33 horsepower oil‑filled motor, the pump can move up to 43 gallons per minute and achieve a maximum lift of 19.25 feet, making it suitable for a wide range of sump basin sizes. The 1.5‑inch discharge port accommodates standard PVC piping, and the 9‑foot cord provides ample reach to a nearby outlet. A vertical polypropylene float switch activates automatically when water reaches the set level, ensuring hands‑free operation. The non‑clogging vortex impeller, forged from the same cast iron, handles solids without jamming, reducing maintenance frequency. All components are finished without additional coating, relying on the inherent corrosion resistance of the materials. The pump operates on standard 115 V AC power, compatible with typical home electrical systems, and comes packaged as a single unit ready for installation.
Usage
This pump is designed for homeowners, property managers, and contractors who need reliable water removal from basements, crawl spaces, and utility rooms. It excels in scenarios where groundwater infiltration, heavy rain, or plumbing leaks threaten to flood living spaces. The robust construction allows continuous operation during prolonged rain events, while the automatic float switch eliminates the need for manual monitoring. Ideal for both new construction and retrofit projects, the M57 can be installed in standard sump pits or custom‑built basins. Its 3/10 HP rating provides enough power to handle typical residential water volumes without overloading household circuits. The pump’s quiet operation and low vibration make it suitable for installation near living areas, and the stainless steel hardware ensures longevity even in high‑humidity conditions. Whether protecting a single‑family home or a multi‑unit building, the Zoeller M57 delivers consistent performance where water control is critical.
