Cutting compressor down-time by 75%

Two pairs of Kaydon K-MOS oil seals were repaired in under two weeks when typical lead times are eight weeks.

Client challenge

An international chemical manufacturer’s Siemens Compressor train had to be closed down because of unacceptable seal oil leakage to sour oil drain. To compound the problem, no serviceable spare seal units were available.

Our response

NASH received the 4 Kaydon seals from both compressors. Our evaluation quickly confirmed that all of them:

  • Were badly coked on all process-side surfaces
  • Were coated internally with hot oil residue
  • Had clearly run hot

We repaired and rebuilt the seals with:

  • New outboard carbon bushes
  • New inboard carbon faces
  • Re-coated and re-lapped shoulders
  • New secondaries and springs

The seals were also:

  • Dynamically tested
  • Returned to site within two weeks

Benefits

  • The compressor train was back in service within 3 weeks
  • Unplanned production losses were minimised
