The WS Effluent Series effluent pump is utilized in effluent wastewater removal, dewatering or water transfer applications where the total head required (including pipe friction losses) does not exceed the pump’s maximum capability. Its gallons per minute performance at 10′ ranges from 90 to 150 gpm.
The Little Giant WS Effluent Series effluent pump is a reliable partner in effluent wastewater removal. Constructed of a rigid cast iron housing, impeller, and volute, the WS Effluent Series efflunet pump is designed for high-torque performance and offer both manual and automatic operation models, as well as a 20′ or 30′ cord option.
