Embodiments are directed to methods and apparatuses for ensuring that mechanisms that are used to position components of an apheresis machine are not broken as a result of rotation of a centrifuge. In embodiments, a safety mechanism is provided that contacts components of the centrifuge and pushes them into a position to ensure that they do not break when the centrifuge is operated at high rpm.

A mechanical seal device for a centrifugal separator includes a first seal ring including a first seal surface and a second seal ring including a second seal surface. The first and second seal surfaces are configured to face each other to form a seal, and at least one channel for a cooling fluid is arranged in the first seal ring. The at least one channel includes an inlet and an outlet. The outlet of the at least one channel is arranged at the first seal surface of the first seal ring. A centrifugal separator includes the mechanical seal device.
