Abstract: A seal arrangement for the gap between a surface of an element rotating around its axis which is to be sealed, and a seal carrier at a distance from it. The seal arrangement includes a sealing ring of a polymeric material, which is at least partially surrounded by the seal carrier in the region of a holder segment and is connected with it so as not to rotate. The sealing ring touches the surface with a lip segment pressed on it in an elastic manner; the sealing ring has at least one ring segment which is expandable by means of a medium to which pressure can be applied, and is pressed against the surface. The ring segment of the sealing ring is arranged at least partially outside of the region of the holder segment surrounded by the seal carrier.
