Abstract
An impeller structure for a centrifugal pump that can feed both fibrous suspensions and water into a headbox of a fibrous web machine. The centrifugal pump utilizing the impeller structure pumps stock for both liquid-laid and foam-laid paper, tissue or board making applications and pumps water or other dilution fluid into a headbox circulation. In general, the impeller of the present invention is especially suitable for all such pumping tasks in the production of fibrous webs that a pulseless or low-pulse impeller is needed.
