ABSTRACT:
An impeller of a centrifugal pump for transporting dirty liquids has transport elements, for example back-vanes or grooves disposed on the pressure side of a cover disk. The transport elements are arranged asymmetrically and are limited to one arc sector of the cover disk to create a transverse stream that rotates with the impeller. Solids which have penetrated into the space to the side of the wheel are carried out by this stream in the direction of the transport elements.
