Submersible Effluent Pump with 20' Cord

Little Giant 9SN-CIA-RF – 4/10 HP Submersible Effluent Pump for Residential and Light Commercial Use

The Little Giant 9SN-CIA-RF is a 4/10 horsepower submersible effluent pump engineered for wastewater and effluent removal in septic systems, sump pits, and basin applications. Built with a cast iron housing and thermally protected motor, this pump is suitable for continuous-duty operation in demanding field conditions.

Capable of handling spherical solids up to 2" in diameter, the 9SN model is designed for effluent applications requiring high flow capacity, solids handling, and system durability. Its permanent split capacitor (PSC) motor ensures low energy consumption and reliable performance over extended run times.
