More Information
Summary:An impeller assembly for centrifugal pumps has two disk members that have different diameters, are arranged coaxially to a rotation axis and face each other so as to form an interspace; blades are radially arranged in the interspace; the two disk members are also centrally provided with a fastening means for fastening to a transmission shaft, which rotates about the rotation axis. The particularity of the present invention resides in having contoured vanes that protrude radially from the peripheral region of the disk member that has the smallest diameter and are arranged substantially at the blades.
