Abstract

The channel impeller for centrifugal pumps according to the invention which is formed by a basic structure comprising a cover plate on the pressure side and a hub body and one or more flow-guiding insert elements fixed to the basic structure possesses considerable advantages over the channel impellers cast in one piece, these advantages deriving primarily from the facility for separate manufacture and machining of the supporting basic structure (1) and the flow-guiding insert element (2). <IMAGE>
