2 Disassembly
When disassembling the seal, inspect for conditions which may have caused 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.
