Sewage Chpper Cutter Pumps

Designed with two cutters namely stationary and rotary cutters. The pump chops as it pumps keeping oversized solids and stringy material from clogging in the downstream. Solids, fibrous and other hard materials are pulled into the pump suction. Before these materials enter the pump impeller vanes, they are cut by the action of the two cutters, so they easily pass through the pump after being chopped several hundred times per minute. The chopper pumps ability to handle large solids and stringy materials make it ideal for use in waste water treatment applications.

A chopper pump is a centrifugal pump which is equipped with a cutting system to facilitate chopping/maceration of solids that are present in the pumped liquid. The main advantage of this type of pump is that it prevents clogging of the pump itself and of the adjacent piping, as all the solids and stringy materials are macerated by the chopping system. Chopper pumps exist in various configurations, including submersible and dry-installed design and they are typically equipped with an electric motor to run the impeller and to provide torque for the chopping system. Due to its high solids handling capabilities, the chopper pump is often used for pumping sewage, sludge, manure slurries, and other liquids that contain large or tough solids.
