Abstract

A pump includes a rotor and a pump housing. The rotor is rotatable about a rotation axis and comprises a rotor hub and a rotor collar. The rotor collar extends from the rotor hub in the radial direction and encircles the rotor hub in an undulating manner. The pump housing comprises a first axial housing component, a central annular housing component, and a second axial housing component. A pump duct is formed (i) in the axial direction by the first and second housing components and (ii) in the radial direction by the central annular housing component and the rotor.
