A drive arrangement includes a housing having two chambers and a partition defining an annular space within the housing. A disk is mounted on a shaft of the drive arrangement and includes an annular portion disposed within the annular space. A face of the annular portion is axially spaced from the partition by a gap clearance. An axial dimension of the gap clearance is such that rotation of the disk generates a negative pressure gradient for drawing fluid from the first chamber through the gap clearance in a radial direction toward the rotation axis. The fluid then moves along the face of the disk in a radial direction away from the rotation axis under centrifugal action of the rotating disk. The outer periphery of the disk is spaced from the housing to permit fluid to pass, by centrifugal action, from the outer periphery toward a second chamber.
