Industrial liquid handling pumps are classified in many different ways, and are distinguished by the media pumped and the fluid motive mechanism (dynamic or displacement).
Industrial mixers use a shaft, screw, blades, ribbons, impellers or propellers to mix industrial materials such as adhesives, chemicals, construction materials, minerals, coatings and paints.
Rotor-stator mixers are single-shaft mixers with an impeller rotating in close proximity to a stationary housing. They are used to rapidly break apart solid particles in a liquid, or to emulsify a liquid into liquids.
