Abstract

The arrangement has a rotor and a projection which is arranged at a front side surface (56) of a corrugation flange in the region of a retaining groove. A circulating groove, which is radially opened outwards, is provided in the projection. A sealing unit (42) is provided in a safety groove, where the sealing unit has a structure which is provided with an opening (63) and a tapped blind hole (65) is aligned with the opening. A locking unit is placed in the hole and in the opening.
