Vaughan Rotamix System

The Vaughan Rotamix System is specified for demanding sludge-handling and digesting duties where complete mixing, reliable solids suspension, and low operating burden matter. Its core value is straightforward: move process contents uniformly, reduce settling, and do it with a package that keeps the tank free of internal rotating hardware. In wastewater, industrial, and dairy/agriculture service, that operating profile supports steadier process conditions and fewer intervention events.

The system pairs fixed nozzle assemblies with Vaughan’s chopper pump to create multi-zone mixing with both rotational flow and a vertical-axis vortex. High-velocity nozzles increase induced flow, extend the effective mixing volume, and help maintain steady velocities across the tank. The chopper pump further conditions the solids stream so the nozzles stay open and the mixing pattern remains effective under heavy-duty service.

Construction is built around abrasion-resistant components, including ductile cast iron fittings, glass-lined surfaces, and tapered nozzle barrels specified for long-term wear protection. The assemblies are permanently set at the factory angle, then protected with fusion-bonded epoxy coating for surface durability. That combination gives the Rotamix platform a practical supply and maintenance story: install, verify, and keep the process moving with minimal internal tank access.

For operators focused on energy and lifecycle cost, Rotamix can be paired with a VFD and Vaughan’s Reduced Energy Advantage strategy to lower power demand while preserving mixing performance. Vaughan also supports the system with CFD analysis, including vector, velocity, and streamline validation for tank geometry and flow behavior. The result is a mixing package that is constructed, specified, tested, and verified for real process conditions rather than general-purpose circulation alone.
