Rotomaxx CX High-Torque Low-Shear Mixer for Chemical Processing

Rotomaxx™ CX is a low-shear, high-torque tank mixer designed for chemical processing applications that require strong circulation and dependable uniformity without aggressive shear. It’s commonly used to improve blending consistency, maintain solids suspension, and promote reliable tank turnover when viscosity or batch volume makes gentle—but powerful—agitation the priority.

Use this page to configure Rotomaxx™ CX around your vessel geometry, viscosity range, and process constraints. If you’re comparing whether agitation alone is enough—or you need rotor/stator shear for wet-out, dispersion, or emulsification—reference our high shear mixer guide and then return here to finalize low-shear equipment selection.

The principle of operation for the Rotomaxx CX high torque mixer is similar to Admix’s Rotomixx CX portable agitator and other top-entry agitators whereby a motor provides power to drive a shaft, and a bearing frame provides support for the motor, coupling and shaft. At the end of the shaft there is a device for pumping fluid, typically an impeller consisting of 3 blades attached to a central hub. The combination of the speed of the shaft rotation and the orientation and type of blades pump the fluid or liquid into which the impeller is immersed.

The mixing impeller is the heart of the Rotomaxx CX mixer and its success in promoting high flow and rapid mix times. Standard Rotomaxx CX units use our Jetfoil™ impeller, providing superior axial pumping rates with minimal power usage. Custom impellers are available to suit specific applications.

As a rule of thumb, the Jetfoil provides TWICE the flow rate and tank turnovers at a given horsepower as compared to conventional pitched blade agitators.
