Abstract

The present invention relates to a space-saving and weight-saving motor-and-pump assembly which comprises a drive motor and a pump unit driven by the shaft of the said motor. In order to supply in parallel as many media as possible with an assembly of this type, the present invention suggests the additional integration of at least one second pump unit, driven by the motor shaft of the drive motor, into the motor-and-pump assembly.
