Compressor Mechanical Seals 

 
Table 10.2 provides information on problems with single units, as well as double and tandem seal 
units. 

Table 10.2  Troubleshooting for Gearbox and Compressor

 

Trouble 

Possible Cause

 

Investigative/Corrective Action

 

Leakage around the seal suddenly 
increases

 

The system is operating at a low flow 
rate or a low inlet pressure, causing 
vibration of the high-speed shaft, 
bouncing on the face of the seal, and 
chipping on the nose of the carbon 
seal. 

 

Make sure that the compressor always 
operates above the specified minimum 
flow rate and/or inlet pressure. 

 

The action of the stationary face 
spring on the seal is rough and sticky 

If contamination in the process gas 
(from entrained solids) causes a sticky 
seal, there may be need for a seal 
flush, double seals, or tandem seals. 
 

 

The seal is worn or damaged. 

Disassemble the seal and rebuild or 
replace it by the instructions in Section 
5. 
 

 

The wear pattern on the rotating faces 
of the seal is not uniform. 

Lightly lap the surfaces on the shaft 
sleeve and the impeller hub that 
contact the rotating face of the seal, to 
remove high spots. Install new seal 
faces. Do not remove more than 0.005 
in. (0.12mm) from any surface. 
 

 

The rotating face of the seal is 
cracked or broken. This may have 
been caused by damage at the 
assembly or by heating due to lack of 
leakage (cooling) past the seal. 

Make sure that the system operates 
above the specified minimum flow rate 
at all times. 

 

 

Check the seal environment to make 
sure that there is a leakage path of 
process or buffer fluid across the 
compressor seal(s) and that there is a 
differential across the seal(s) to force 
this leakage. Replace the damaged 
seal. 
 

 

The seal faces, seal parts, or o-rings 
have become chemically attached. 

Investigate the properties of the 
process gas, and replace the 
components with chemically resistant 
materials. 
 

 

The seal on a low-temperature 
compressor is icing, or there is heavy 
condensation on the atmospheric side 
of the seal. 

Purge the atmospheric side of the seal 
with dry nitrogen gas.
