摘要：The invention relates to a single seal, and more specifically to a seal for a rotary shaft extending through a wall, e.g. that of a pump housing. The single seal exhibits one single sealing location between a fixed and a rotary sealing ring. The seal is fitted onto the wall by means of a flange in order to seal off a chamber inside the wall against the
shaft and towards the exterior. According to the invention, the single seal exhibits an outer sealing ring () and an inner sealing ring (). These sealing rings are in sliding and sealing contact with each other. The outer sealing ring () is fastened to the flange () and the inner sealing ring () is fastened to an axially displaceable sleeve (). The sleeve is in turn affixed to and rotating with the shaft (), and extends through the wall and the flange (). The seal also has a spring device () arranged outside the wall and providing a force for increasing the contact between the sealing rings ().
