摘要
The invention relates to a rotor wheel constructed of sheet metal for a centrifugal pump, particularly a multi-stage centrifugal pump, with means for fastening to the drive shaft of an electric motor, wherein the rotor wheel has a central coaxial opening in which a sleeve is fastened coaxially, wherein the sleeve projects out of the rotor wheel on at least one side of the rotor wheel, and wherein the sleeve has, in its inner wall, projecting, axially parallel ridges for fastening into axially parallel notches or grooves of the motor drive shaft.
