ABSTRACT:
A multibladed propeller shaped agitator includes a plurality of impellers having made blades, blade roots and hub segments made of plastic material. A metallic hub element is inlaid only in the hub segment. The impellers are connected to the hub segment such that stress peaks, imparted from a driving force, in the region of the blades, blade roots and hub segments are substantially prevented.
