The shaft no longer rotates in a polygonal support, but is supported and guided over its entire circumference, thereby reducing vibrations. The shaft rotation promotes a powerful pumping action in the involuted channels, which leads to a considerably increased fluid velocity in the channel and remarkable cooling, lubricating and cleaning effects.
