Abstract

A seal assembly for providing a seal between a first zone and a second zone includes a rotatable sealing member including a first sealing ring, a stationary sealing member including a second sealing ring and a device for bringing the first and second sealing rings into engagement with each other. The first and second sealing rings are arranged so that a double contact seal having at least one chamber arranged at a radial plane is formed upon engagement between the first and second sealing rings. The seal assembly further includes at least one fluid connection to the chamber. A centrifugal separator includes such a seal assembly.
