A sealing device is provided. The sealing device is for sealing a space formed by an inner shaft and an outer shaft and for directing a flow of fluid, the inner shaft and the outer shaft being rotatable about a common coaxial axis. The sealing device includes an inner seal element adapted for being coupled to the inner shaft so that the inner seal element is locked against rotation relative to the inner shaft, the inner seal element including a first inner sealing surface. The sealing device further includes an outer seal element adapted for being coupled to the outer shaft so that the outer seal element is locked against rotation relative to the outer shaft, the outer seal element including a first outer sealing surface. The first inner sealing surface and the first outer sealing surface are adapted to form, by contact with each other, a first seal area including a first channel arrangement including at least one channel configured to actively drain a fluid from the first seal area when the seal elements rotate with respect to each other.
