A non-chokable pump includes an impeller having vanes for delivering solids-containing media. At least a portion of the vanes include a vane section that branches from a vane extending from a hub region of the impeller. The vane section preferably has a curvature greater than the vane extending from the hub region.

Vortex pump

A centrifugal pump for delivering a medium comprising solid admixtures includes a blade-free space arranged in front of an impeller. The centrifugal pump has a suction-side arrangement that permits variable sizing of the blade-free space. The suction-side arrangement permits the efficiency of the centrifugal pump to be increased while avoiding blockages.

A vortex pump with an impeller is provided. The impeller includes blades for delivering solids-containing media which are arranged in bundles. The spacing the blades in the bundles is smaller than the spacing of the bundles from each other.

A rotor mounting on one end of a shaft, particularly a shaft end of a centrifugal pump unit, in which an adjusting surface and at least one contact surface are constructed on the shaft end, and in which a rotor hub is provided at least on the end facing the shaft with a central bore having an internal thread. The rotor hub is attached to the shaft end by a screw connection. The shaft has a central bore () having an internal thread () at least on the end facing the rotor hub (); a threaded pin () constructed as a separate component is disposed in both central bores () in a connecting, torque-transmitting and force-transmitting manner, and the rotor is aligned on the shaft solely by the adjusting surfaces () and contact surfaces ().

Rotor mounting

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.
