6 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 Safety Data Sheet (SDS) 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.
