Elastomer Bellow Mechanical Seal
01
Water Pump Seal Unbalanced Pusher Type Replace John Crane 1A
Product Description
+
This component is a robust rubber diaphragm seal designed with self-adjusting seal head and mounted parallel spring. The drive of the shaft is achieved by a diaphragm bellows clamping the shaft tightly and providing positive drive to the seal head and sealing face. Its diaphragm seal design protects the shaft and sleeve from wear and scoring as the spring provides constant forces to the contact point, while the drive band and notches eliminate excessive stress on the bellows.
It is available in metric and inch sizes and follows the standard EN 12756, compatible with the Flowserve 2 1/2 LR-10, Flowserve 2 1/2 LR-13, Flowserve 4 LR-11 and others.
Its stationary suits common metric and imperial UK and European extended-length seal chambers.
