• 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 (Piggyback variable level float switch available separately)
• Non-clogging, engineered thermoplastic vortex impeller design. The vortex impeller allows free passage of solids to prevent clogging.

The 1/3 HP Model N151 nonautomatic Effluent Pump is designed to pump sewage effluent in septic system applications. It is an ideal choice in high pressure or high flow 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.
