The invention relates to a friction vacuum pump (1) comprising a fixed element (7) bearing rows of stator blades and a rotating element (6) bearing rows of rotor blades. The rows of stator blades and rotor blades are arranged concentrically with respect to the axis of rotation (4) of the rotating element (6) and engage with each other. In order to create a short friction pump, the elements (6, 7) bearing the rows of rotor blades and stator blades extend in a substantially radial manner and the longitudinal axes of the blades (2, 3) extend in a substantially axial manner. A friction vacuum pump (1) comprises a fixed element (7) bearing rows of stator blades (3) and a rotating element (6) bearing rows of rotor blades (2). The rows of stator blades and rotor blades are arranged concentrically with respect to an axis of rotation (4) of the rotating element (6) and mesh with each other. In order to create in the axial direct a short friction pump, the elements (6, 7) bearing the rows of rotor blades and stator blades extend in a substantially radial manner and the longitudinal axes of the blades (2, 3) extend in a substantially axial manner.
