Our Model N98 nonautomatic Effluent Pump is designed to remove unwanted water in sump or septic effluent applications. The professional-grade, 1/2 HP N98 is the industry standard when you need a higher flow sump pump. Known as the ''Flow-Mate'' the N98 is a nonautomatic pump requiring a piggyback float switch or control panel for operation. Either option allows you to set the on and off point of the pump in the field.The Model 98's 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 98 is able to withstand demanding, high flow basement sump applications.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.
