Abstract
The driving shaft (3) of a pump impeller (4) is extended beyond the impeller and supports the mixer (5) at its end. In order to minimize the risk for extensive damage if the mixer should hit a solid body, the shaft (6) of the mixer is very slim and manufactured of an elastic material such as spring steel.
