Abstract (en)
[origin: EP2458221A2] The pump has a rotor, and a sheet rotor disk comprising a supporting ring and two partial disks, where the partial disks are provided with respective supporting ring sections (56, 58). The rotor has a shaft, and the rotor disk is arranged on the shaft. One of the ring sections has an abutting surface (64) that is tilted against a disk plane (54), where another ring section is pushed against the abutting surface. The abutting surface is arranged at a latch (62) that works together with a stator component for fixing one of the partial disks in a radial plane.
