Abstract
An automotive electric liquid pump includes a separation can having a radial inside which includes a static bearing ring, a pump rotor, and a motor rotor which rotates in the separation can. The motor rotor includes a radial outside having a cylindrical rotor bearing ring. The static bearing ring of the separation can corresponds to the cylindrical rotor bearing ring of the motor rotor. A first radial slide bearing is defined by the cylindrical rotor bearing ring and the static bearing ring.
