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. These are available from
numerous Flowserve stocking locations. To order replacement parts,
refer to the part code number and B/M number. A spare backup seal
should be stocked to reduce repair time.
When repairs are not conducted at the customer’s location,
decontaminate the seal assembly and return it to Flowserve, with
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 in its original condition.
