An axial end of the container is sealingly connected to a motor housing of a drive motor (2) e.g. canned motor and electric drive motor. Another axial end (20) of the container is connected to the former axial end in a closed manner. The container comprises a closed wall and suction and pressure openings (24, 26) that extend away from the container in a radial direction. The openings are provided with connection flanges (30). The openings are directly welded to a connection line.
