High Shear Mixer 400 Series - 25 HP

Model: HSM-425



Add VFD:


The Inline Model High Shear Rotor-Stator mixer design consists of a single, dual or four stage rotor that turns at high speed within a stationary stator. As the rotating blades pass the stator, they mechanically shear the contents.

The Inline model is a good choice for process lines that require frequent changeover from one product to another. A simple valve can divert finished product downstream or switch instantly from one vessel to another.

Interchangeable rotor-stator combinations provide unlimited flexibility to adopt to a variety of product formulations.
