As with every Zoeller® pump, each one is 100% pressure-tested, submerged and run to ensure quality and reliability for years of trouble-free performance. This attention to detail is an inherent feature of every pump in this series, making it one of the most reliable in the industry.

Built for professional-grade performance, the 3/10 HP M57—also known as the “Mighty-Mate”—is a proven and dependable automatic solution. Its operation is controlled by a solid, white polypropylene float that remains permanently buoyant, ensuring reliable activation of the pump when needed. Designed with a vortex-style impeller, the M57 can handle 2″ spherical solids with ease. Constructed for durability, its switch case, motor housing, pump housing, and base are all made of rugged cast iron and the pump’s identification tag, float guard, handle, switch arm, and hardware are made of non-corrodible stainless steel, making the Model 57 ideal for even the most demanding basement sump applications. The Zoeller 57-0001 includes a 9 ft cord. Every Zoeller M57 pump is fully submerged and tested to its published performance curve before shipment, ensuring peace of mind straight out of the box and operations that exceeds expectations.
