ABSTRACT:
A rotating liquid pump, especially a vane cell pump, which is equipped with a disc-shaped rotor which together with a housing encloses at the circumference rotating feed spaces and which is non-rotatably but axially movably retained on a drive shaft by means of a form-locking connection while the disc-shaped rotor is axially fixed between housing walls that abut end-face at the disc-shaped rotor; the form locking connection is thereby subdivided into two separate axial mounting or support areas located as close to the disc-shaped rotor end faces as possible.
