    • The present invention is directed to an automotive electric fluid pump (10) with: - an electromagnetic motor stator (22), - a permanent-magnetic motor rotor (28), - a pot-shaped metallic separating can (36) comprising:  a cylindrical separating can sidewall (40) which extends through a cylindrical gap between the motor stator (22) and the motor rotor (28), and  a transverse separating can bottom wall (42) with a bottom wall protrusion (44) which axially protrudes from the separating can bottom wall (42) at a motor-rotor-remote axial side, and - an electrically conductive separating-can grounding element (48;48') which is configured to electrically connect the separating can (36) with a ground potential, and which comprises a clamping arrangement (52;52') which is in touching contact with a radial outside surface (54) of the bottom wall protrusion (44). The separating-can grounding element (48;48') with the clamping arrangement (52;52') provides a reliable electrical grounding of the separating can (36) so that the automotive electric fluid pump (10) according to the present invention has constantly low electromagnetic radiation.
