What is a chopper pump?
Chopper pumps are centrifugal pumps with the capability to handle fluids with a high concentration of solids. Chopper pumps have a cutting attachment made of hard materials of fixed and rotating elements that macerate solids before entry to the impeller, allowing it to handle difficult materials. Solids are cut so they pass through the pump more easily and flow out with the rest of the pumped fluid. Chopper pumps’ ability to handle solids gives them more flexibility in what they can pump. This characteristic makes them particularly useful in wastewater treatment plants. Wastewater treatment is split into primary treatment and secondary treatment. Primary treatment is the physical separation of floatable materials and insoluble solids from the wastewater. Secondary treatment is biological treatment of water using microorganisms to remove the remaining solids in the fluid. Both treatments contain solids in the pumped fluid and may require chopper pumps.
