Municipal Chopper Pumps are centrifugal pumps specifically designed to chop incoming solids before pumping, ensuring protection against clogging and delivering additional benefits to downstream components, processes, and the environment. These pumps feature robust wear components made of cast steel and heat-treated for exceptional impact and wear resistance.
With Vaughan's innovative vertical wet well design, which has been trusted for nearly half a century, the scissor action of the impeller vanes cutting against the cutter bar achieves efficient chopping. As a result, all solids are effectively chopped upon entry, allowing the centrifugal action of the impeller to effortlessly pump smaller solids. Experience the ultimate solution for handling severe solids with our durable and reliable municipal chopper pumps.
Features & Benefits of Vaughan Chopper Pumps:

 - Hydraulic efficiencies OVER 70%
 - Discharge sizes from 3″ to 16″
 - Heat-treated and hardened components
 - Direct or belt-drive configurations available
 - Over 50 years experience
 - Non-clogging guarantee on all Chopper pumps
 
Wastewater Applications for Vaughan Chopper Pumps:
- Raw Sewage: Lift stations, CSO facilities, headworks, prisons, hospitals, restaurants.
 - Screenings / Septage: Raw concentrated solids including rags, plastics and hair.
 - Clarifier Scum Pits: Primary or Secondary scum without plugging or air binding.
 - Sludge Transfer: Eliminates “roping” and clogging in clarifier underflow to thickeners.
 - RAS / WAS: Continuously conditions Return and Waste Activated Sludges.
 - Thickened Sludge / Digested Sludge Transfer: Handles high sludge consistencies.
 - Digester Mixing: Rotamix system conditions and mixes in a dual-zone rotational flow pattern.
 - Digester Recirculation: Eliminates heat exchanger clogging while conditioning sludge.
