Abstract

The invention relates to a pump unit (2) comprising an electric motor and at least one feed pump for conveying hydraulic liquid. The electric motor comprises a drive shaft (12). The at least one feed pump comprises a pump rotor (22) that can be driven by the drive shaft (12). The drive shaft (12) and the pump rotor (22) are arranged in such a way that the pump rotor (22) can be driven by means of the drive shaft (12) in a torsionally rigid manner.
