5 Repair
This product is a precision sealing device. The design and dimension
tolerances are critical to seal performance. Only parts supplied by
Flowserve should be used to repair a seal. To order replacement parts,
refer to the part code and B/M number. A spare backup seal should be
stocked to reduce repair time.
When seals are returned to Flowserve for repair, decontaminate the
seal assembly and include an order marked "Repair or Replace." A
signed certificate of decontamination must be attached. A Material
Safety Data Sheet (MSDS) must be enclosed for any product that
came in contact with the seal. The seal assembly will be inspected and, if
repairable, it will be rebuilt, tested, and returned.
