Abstract
Official abstract text for this publication.
An impeller ( 2 ) for a centrifugal pump includes a first shroud having a plurality of blades ( 8 ). A second shroud is joined onto the first shroud by way of welding. Each blade ( 8 ) has an apex region ( 12 ), at which the blade contacts the second shroud. At least one of the blades ( 8 ) in a first section ( 20 ) of the apex region ( 12 ) has a weld connection to the second shroud, and in at least one second section ( 14 ) of the apex region ( 12 ) is free of a weld connection.
