Abstract

1,174,636. Seals. CRANE PACKING Ltd. 16 Sept., 1968 [15 Sept., 1967], No. 42156/67. Heading F2B. A laminated ring 6 comprising the turns of a helix forms a flap valve type seal when the pump shaft 3 is at rest. The seal 6 may be made of P.T.F.E. and may be wound on to or off the shaft after loosening a support ring 8 which can either be screwed on the shaft or provided with grub screws. When the pump is operational, the seal is lifted from its seat 9 by centrifugal force.
