A centrifugal pump for transferring solid particles from a low pressure zone into a high pressure zone comprises a centrifugal rotor and a housing that are each rotatable about a central axis. The rotor debouches particles into the interior of the housing and a screw conveyor is arranged in the housing for transporting particles along the inner surface of the housing to an outlet which is coaxial to the central axis.
