An electric motor vehicle coolant pump for cooling an internal combustion engine of a motor vehicle includes a pump housing and a rotor rotatably supported in the pump housing. The rotor comprises a motor rotor configured to be substantially pot-shaped. The motor rotor comprises a pot bottom and a ferromagnetic substance so as to be magnetized in at least a bipolar manner. A pump rotor comprises a plurality of rotor blades and an annular cover ring arranged on distal ends of the plurality of rotor blades. The plurality of rotor blades are configured to stand directly on the pot bottom of the motor rotor. The pump rotor and the motor rotor are each integral plastic material parts separately produced by an injection molding. The pump rotor and the motor rotor are made from different materials. The pump rotor is not ferromagnetic.
