Rotamix Mechanical Hydraulic Mixing Systems

Since 1960 USA based original chopper pump manufacturer Vaughan Co. has been the market leader in manufacturing chopper pumps. All Vaughan’s upgrades and improved spare parts are interchangeable with all pumps ever manufactured by Vaughan Co. The only pump with a non-clog guarantee also benefits downstream components, processes and the environment. While Vaughan’s Rotamix mechanical hydraulic mixing system is the most reliable, effective and cost effective process mixing system for digesters, sludge storage and other high volume applications available on the market today.
