Little Giant’s WS Series sewage pump is ideal for handling raw sewage as well as commercial dewatering sump applications with up to 2″ solids. This series offers multiple options with one-phase and three-phase pumps and controls.
Rugged enough to handle the challenges of raw sewage, the WS Series sewage pump is built with solid cast-iron construction and includes a 1/2 or 1 hp motor with an oil-filled chamber and double ball bearing. The non-clog impeller moves the sewage seamlessly through the discharge. Designed for hi-torque and is thermally protected with automatic reset (single-phase only).
