When disassembling seal, inspect for conditions which may have caused the
need for the seal to be removed from service. If seal was removed due to
premature failure, determine what conditions caused that failure and correct any
problems prior to returning the repaired seal to service. For assistance with seal
failure analysis, please contact your Flowserve representative.
