Stirring Unit/Dilution Mixer

Stirring Unit/Dilution Mixer

by GRIESER 2018

Deutsch  |  English

Stirring, homogenizing, agitation or aeration of liquids, solutions, paints and coatings or other low viscosity products, as well as dilution of granulates or chips in liquids.


Stirring units are ideal for the use in barrels, IBCs, containers or stationary mixing vessels up to 50,000 liters.

The stirring unit offers a compact and robust design that is available in all common motor sizes.

Depending on the product viscosity and engine power the agitator shaft is either directly connected to the motor or driven by a geared motor with a separate bearing hood.

In dependence of the mixing task and the product viscosity, different mixing tools are used:

  • Folding propeller for the use in IBCs
  • Anchor agitator for gentle, mostly tangential circulation
  • Blade agitator for gentle, tangential and radial circulation
  • Disk agitator for gentle or intense, predominantly radial circulation
  • Paddle agitator for gentle to intense, predominantly axial circulation
  • Propeller, turbine agitators or butterfly-mixing tools for gentle to intense, axial and radial circulation
