A shaft sealing assembly (100) for static and dynamic axial sealing of a centrally located rotatingly movable shaft (10). The assembly (100) comprises at least one first sealing member (8) sealing said shaft (10), at least one rotor member (3,6) attached to said shaft (10), and a stator member (1) attached to a housing (30). A first sealing member (8) is arranged in a recess (7) in said rotor member (3) effectively sealing one side of the assembly (100) from its other side when a pressure difference is existing between the media on the two sides. Upon rotation of the shaft (10), the static sealing member (8) is centrifugally moved axially and radially away out of its static sealing position and friction between the sealing member (8) and the stator (1) is eliminated. Dynamic sealing is effected by a pressure difference caused by a turbine effect of the rotor member (3, 6).
