Abstract: A contactlessly, inductively, or magnetically drivable agitator (1) for fluids, in particular for agitating sterile fluids which is equipped with a separating vessel (10) and an agitator head (2), which is supported thereon in an axially and radially movable fashion and is for supporting agitating elements (5). The novel agitator (1) includes structures for hydrodynamically generating a fluid film from the medium to be agitated and during operation, the fluid film is formed between at least one stationary part of the separating vessel (10) or a container bottom (11) and at least one part of the rotationally movable agitator head (2) that is equipped with the hydrodynamically acting structures. During operation, the fluid film eliminates essentially all of the pressure on the bearing, drastically reduces the wear, and as a result, practically no further abraded material gets into the fluids to be agitated. Such agitators permit maximum speeds of up to 3000 rpm.
