Our Model BN151 nonautomatic Effluent Pump is designed to remove unwanted water in septic effluent applications. It is an ideal choice in high pressure or high flow applications. The professional-grade, 1/3 HP Model 151 is known for its dependability. The BN151 is a nonautomatic pump equipped with a single piggyback float switch. The piggyback float switch allows you to set the on and off point of the pump in the field. This is ideal in an application with a deep sump pit or pump tank. The Model 151'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, handle, and hardware are made of non-corrodible stainless steel. This attention to detail ensures that the Model 151 is able to withstand the most demanding 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.

• Oil filled for optimal heat dissipation: This design minimizes concerns about the pump overheating or breaking down due to extreme heat generation during extended-use applications.
• Nonautomatic pump with piggyback variable level float switch which allows you to adjust the on / off level for optimal runtime
• Non-clogging, engineered thermoplastic vortex impeller design. The vortex impeller allows free passage of solids to prevent clogging.
• The single piggyback float switch turns a nonautomatic pump into an automatic pump and also allows you to isolate the pump from the switch making it easier to troubleshoot issues in the field
• For strength and durability, this pump includes a corrosion-resistant, powder-coated epoxy finish, cast iron construction, and stainless steel lifting handle and bolts.
• Stainless steel screws, handle and hardware to prevent rust and corrosion over the life of the pump
• 100% factory tested: Our factory-tested effluent pumps ensure reliable performance in challenging applications with fewer concerns about mechanical failures
• 3-year limited warranty: this model comes with warranty coverage from Zoeller Pump Company, giving you extra protection and more peace of mind
