Found this very useful presentation on dry gas seal basics.

It's really helpful.
Try it.

Attached is a useful presentation for Pump Seal Installation by John Crane.

This type of comparison is not done normally, but you may use Maimo for this. Comparsions can be made keeping in consideration the MTBF ( Mean Time Between Failure).

Can anybody share the purpose of tertiary seals in a dry gas seal of compressor?

What are the possibilities of carboblasting material deposition over the compressor blades, in case their is an excessive lube oil leakage from the turbine bearing # 1 resulting in the formation of possible sludge on the compressor blades?

We are planning to perform the Carboblast cleaning on one of our Gas turbines. Can anybody share the details of Carboblast cleaning. What is the procedure? What is used for cleaning? How much time should be taken for cleaning etc? Its a GE frame 5 gas turbine.

Thank you Ben, we will revert back to you after all these checks

Do you have a rod drop system installed at your machine? If not then you should also inspect its rider band
