Abstract

The invention concerns a non-clogging pump of centrifugal or axial flow type. The regular vanes (6), (11) of the impeller or the pump housing are completed with a number of additional vanes (8), (13) between the regular vanes and so arranged that their front edges (9), (14), as seen in the direction of the flow, are located in front of the front edges (7), (12) of the regular vanes. <IMAGE>
