Profile: Thornton & Co. specializes in industrial pumps. Our 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. Our Rotamix® system is used for digesters, sludge storage and other high-volume applications. Rotamix® system improves volatile solids reduction, increases gas production, reduces sludge volume, and saves energy during non-peak hours.
