Abstract
A seal for producing a liquid-tight closure between a rotary component and a partition separating two chambers, where the rotary component penetrates the partition, said seal includes a retaining means which may be secured to the partition so that it surrounds the rotary component. The retaining means locates an annular floating member, so that it is free to float radially. The annular floating member has a small clearance about the rotary component and is provided with sealing means which will close the gap between the floating member and the rotary component to form a liquid-tight closure, upon exposure to liquid, following the flooding of one of the chambers.
