Vaughan Chopper Pumps – Proven Non-Clog Solids Pumping

Vaughan Chopper Pumps are centrifugal pumps with the unique ability of chopping all solids prior to pumping.  This not only protects the pump from clogging, but also provides added benefit to downstream components and processes. All wear components are cast steel and heat treated for maximum impact and wear resistance.  Combined together, these heavy duty patented components create the ultimate pump for handling severe solids.  

This same basic concept has been used in the vertical wet well design for almost a half century. Chopping is accomplished by the scissor action of the leading edges of the impeller veins cutting against the opposing edges of the cutter bar.  All solids are chopped as they enter between the cutter bar and the impeller veins  The smaller solids are then easily pumped by the centrifugal action of the impeller. 

RAW SEWAGE – Used in Lift stations, CSO facilities, headworks, prisons, hospitals, restaurants

SCREENINGS / SEPTAGE – Easily chops raw concentrated solids including rags, plastics and hair

CLARIFIER SCUM PITS – Transfers or conditions Primary & 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

TANK MIXING – System conditions and mixes in a dual-zone rotational flow pattern

DIGESTER RECIRCULATION – Eliminates heat exchanger clogging while conditioning sludge

F.O.G – (Fats, Oils, and Grease) – Uses organic waste to enhance methane production
