Zoeller Model D53 Sump Pump Description

The Model D53 is designed to remove unwanted groundwater in basement sump applications. The professional-grade 3/10 HP Model D53 is the industry standard when it comes to primary sump pumps. Know as the "Mighty-Mate" D53, it is a fully automatic float-operated sump pump. The white polypropylene float is solid so it cannot become waterlogged. This ensures that it is always buoyant and able to turn the pump on when necessary.

The Model 53's switch case, motor housing and pump housing are each constructed of cast iron. The corrosion resistant engineered plastic vortex impeller has a smooth surface allowing water and solids to pass freely through the pump. The pump's identification tag, float guard, handle, switch arm and hardware are made of non-corrodible stainless steel. This attention to detail ensures that the Model 53 is able to withstand the most demanding basement sump applications.
