The invention concerns a cooling device for an electrically driven mixer operating in hot liquids. The motor (1) is surrounded by a cooling jacket (5) having inlet (8) and outlet (9) for cooling medium. The jacket (5) is provided with a concentric partition wall (6) which devide the room inside the jacket into two gaps (7) and (8) respectively of different widths.

Cooling device

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.
