Flowserve Sales and Service Representative or Authorized Distributor.
7 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.
