TAMSEALâ„¢ Pocketed Damper Seals

TAMSEAL pocketed damper sealsTAMSEAL pocketed damper seals are a superior alternative to conventional labyrinth seals. The TAMSEAL pocketed damper seal reduces or eliminates machine vibrations while providing 50 to 100 times more damping than conventional labyrinth seals. In addition to high damping, pocketed damper seals are tolerant to fouling and particulate build-up, which can be disadvantages when using honeycomb or hole pattern seals in working with fluids containing impurities.

Pocketed damper seals are also able to be used in applications requiring a short seal length or small L/D, whereas honeycomb and hole pattern seals require a significant axial length for effective operation. This characteristic allows the TAMSEAL pocketed damper seal to be used in areas where the axial envelope is limited, such as impeller eye seal locations.

Like the hole pattern and honeycomb seals, pocketed damper seals are engineered in-house using a benchmarked and proven bulk-flow analysis tool, which is able to optimize the leakage and dynamic coefficients for a specific application. Pocketed damper seals can be manufactured using conventional metals or high-performance plastics such as PEEK.

TAMSEAL applications include rotating machinery operating in compressible fluids, including compressors, gas turbines and steam turbines.

 

Key Benefits

  • Provide 50 to 100 times more damping than conventional labyrinth seals
  • Withstand high pressure, while honeycomb seals are limited by the strength of the brazing bond
  • Insensitive to fouling – not affected by the cleanliness of the process gas
  • Short axial length to provide excellent damping at impeller eye and shaft interstage seals
  • Require no modifications to the rotor or housing
  • Accepted and field proven by industry leaders
