Rotamix – The HEART of the System

Vaughan Chopper Pump

Vaughan’s chopper pump is the heart of the Rotamix System. Vaughan’s proven technology over the past 40 years provides long term low maintenance, and the highest reliability of any chopper pump. Continuously chopped solids not only eliminate nozzle clogging, but enhance sludge quality. Digester efficiency is increased by further reducing solids size and increasing surface contact.
Vaughan’s unique features necessary to provide this reliability include:

Patented chopping design eliminates nozzle clogging
Wear parts heat treated to 60+ Rockwell C Hardness extends pump life
Oversized shafting and bearings extends pump life
Heavy duty mechanical seal (optional “flushness” seal design) assures leak-free operation
Back pull-out design allows adjustment of all cutting clearances without disconnecting suction or discharge piping

Other configurations available include vertical dry pit, submersible, self-priming, vertical wet well, and recirculating pumps. All Vaughan pumps include a written Performance Guarantee, your assurance of clog free pump operation.

Typical Municipal Flow Diagram

The numbers in the table below correspond with the numbers on the diagram.

RAW SEWERAGE – 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.
As above
THICKENED SLUDGE / DIGESTED SLUDGE TRANSFER – Handles high sludge consistencies.
As above
DIGESTER MIXING – Rotamix system conditions and mixes in a dual-zone rotational flow pattern.
DIGESTER RECIRCULATION – Elimiates heat exchanger clogging while conditioning sludge.
