Abstract
An electrical automotive liquid pump includes a pump housing, a drive shaft which is co-rotatably connected to a pump wheel, an electrical drive motor having a motor rotor and a motor stator, and a separating tube which fluidically separates the motor rotor and the motor stator to define a wet zone and a dry zone within the pump housing. The motor rotor is co-rotatably connected to the drive shaft. The separating tube has an integral bearing seat structure which includes a bearing seat and a supporting structure. The supporting structure is defined by blades which connect the bearing seat with the separating tube. Each of the blades are arranged at a pitch angle with respect to a rotor axis so that a turbine-type shape is defined for the integral bearing seat structure. The bearing seat is provided with an integral plain bearing shell which directly supports the drive shaft.
