In mixing technology, a large variety of impellers is used for a wide range of applications. The various designs can be traced back to a few basic types. The dimensions and designations of these are standardized in DIN 28131.

In principle, it is useful to categorize agitators according to the following aspects:

• Primary flow direction: axial, radial or tangential,
• Close to the wall and central operating impellers,
• Tip speed
• Viscosity range or flow regime: laminar, turbulent or transitional.

In addition to the desired axial or radial flow, each agitator also generates a tangential flow through the transmission of the rotary movement to the liquid. A three-dimensional flow thus prevails in a mixing vessel. This flow field is strongly influenced by components in the container. Undesired tangential flow in the stirring system can often be reduced by the installation of baffles on the vessel wall.
