The 0.30 HP Model N53 Effluent Pump with a 25' cord is designed to remove groundwater from basement sump, effluent, or septic applications. This corrosion resistant pump will provide the dependability expected from a Zoeller pump. Backed by a 3-year warranty, every pump is submerged in water and tested to its published performance curve, ensuring it meets your expectations and delivers peace of mind right out of the box.The Model 53's switch housing, 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, handle, 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 applications.
