SHAFT INFLATABLE SEAL - MAINTENANCE INSTRUCTIONS.
a. A feature of the marine split shaft seal is the split, inflatable sealing ring which is located in a recess in the
seal housing; just off of the sealing element cavity. The inflatable sealing ring, when not in use, does not contact the
shaft surface.
b. When it is necessary to interchange or replace the sealing element, the inflatable sealing ring is inflated with
air from an appropriate source, and forms a restriction around the stationary shaft, restricting sea water ingress and
permitting seal repair. After the interchange or replacement of the sealing elements is completed, the inflatable ring
is deflated, receding back into its recess, loosing contact with the shaft.
