Chopper Pumps are centrifugal pumps 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 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. 

Rotamix systems includes a Vaughan Horizontal End Suction Chopper Pump in combination with Vaughan Mixing Nozzles that mount either through existing manways in the roof or on the floor.  Roof mounts allow retrofit without tank cleaning.  Floor mounted nozzles are for more permanent installations.  Nozzle sizing is dependant on mixing requirements and digester capacity. Mixing action is based on rotation of the digester contents.  This cost effective system provides ease of access to the pump for routine maintenance, and increases overall efficiency by chopping and pumping solids continuously, all for less cost than conventional mixing systems.
