Pumps

Welcome to 50+ Years of Reliability

The Vaughan Chopper Pump is a centrifugal pump with the unique ability of chopping all incoming solids prior to pumping. This not only protects the pump from clogging, but also provides added benefit to downstream components, processes, and the environment.

All wear components are cast steel and heat treated for maximum impact and wear resistance. In combination, these heavy duty patented components create the ultimate pump for handling severe solids. Indeed, it is often used as a dedicated grit pump for applications in the sewage treatment industry.

This same basic concept has been used in Vaughan’s vertical wet well design for almost a half-century.

Chopping is accomplished by the scissor action of the leading edges of the impeller vanes cutting against the opposing edges of the cutter bar.

All solids are chopped as they enter between the cutter bar and the impeller vanes. The smaller solids are easily pumped by the centrifugal action of the impeller.

The pump offers very high efficiencies and these have been optimised in the design using Computational Fluid Design (CFD) simulation technology.
