Chopper pumps are used extensively in heavy-duty solids-laden water applications including municipal wastewater, industrial sewage, food processing, agricultural byproduct, and raw untreated drainage run-off from metal, paper and chemical industries. Chopper pumps increasing popularity can be attributed to the combination of increasing solids in water streams and decreasing water drain-off from residential, commercial and industrial sources. Chopper pumps solve the biggest challenge that municipalities and private wastewater treatment operators face – pump clogging.
