Vaughan Company
About
Vaughan Company, founded in 1960 and based in Montesano, Washington, is the originator of the chopper pump—a centrifugal pump with integrated cutting elements that shred rags, wipes, and solids during pumping to prevent clogging. The company holds over 40 patents and manufactures all products domestically, meeting Build America, Buy America (BABA) requirements. Beyond chopper pumps, Vaughan produces the Rotamix hydraulic mixing system for anaerobic digesters and sludge tanks (backed by a 10-year nozzle warranty), Triton screw centrifugal pumps for viscous flows, portable bypass trailers, stormwater-specific Chopper Storm units, and recirculator pumps. They maintain a $10M spare parts inventory and serve municipal wastewater, industrial process water, lift stations, agriculture and dairy, and saltwater disposal markets.
