Abstract
A submersible pump assembly for use in a borehole, including a screw pump and/or an eccentric screw pump with a longitudinal axis. The submersible assembly further includes a drive and a bearing arrangement for taking up and diverting the axial and/or radial forces arising during the operation of the screw pump and/or eccentric screw pump. The drive is disposed, via a first coupling rod, at one end of the screw pump and/or eccentric screw pump and the bearing arrangement is assigned, via a second coupling rod, to the opposite end of the screw pump and/or eccentric screw pump along the longitudinal axis.
