• Oil filled motor optimizes heat dissipation which prevents the pump from overheating during extended-use occurrences
• A versatile nonautomatic pump that can be paired with your choice of a piggyback float switch or a control panel with control floats to cover a broad range of sump pit configurations
• Built with an engineered plastic vortex impeller to allow free passage of 3/4'' spherical solids to prevent the potential for clogging

The 1/2 HP Model N153 nonautomatic Effluent pump with a piggyback variable level float switch is designed to pump sewage effluent in septic systems and to pump elevator sump water. It is constructed of cast iron with a durable powder-coated epoxy finish to reduce corrosion, making it ideal for most septic system pump tanks. The Model N153 works well in residential and light commercial applications and is a desirable choice for longevity. Backed by a one-year warranty, every pump is submerged and water tested to provide years of trouble-free performance.
