Chesterton 4410 Dry Gas Seal for Slow Speeds
Low-Speed, Easy-to-Install, Gas-Lubricated Seal

  

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​

​​​​​​​Chesterton 4410 dry gas seals offer the same reliability and advanced features of the Chesterton 4400 gas-lubricated seals — with a design customized for low-speed applications.

  • Delivers higher reliability with lower gas consumption than conventional gas-lubricated seals
  • Transitions to a traditional liquid seal in the event of the loss of barrier gas and recovers to a gas seal upon restoring the barrier gas
  • Compact flush mount design that does not require modification of the stuffing box; fits more equipment types than conventional dry gas seals
  • Innovative ​In-Gland Control System (IGCS) dynamically controls gas pressure to process pressure​
Low speed designs provide lift-off at speeds down to 10 RPM
Zero fugitive emission, monitoring exempt, dual gas seal design
Adjustable gland tabs
Full sealing recovery following loss of barrier gas
Unique design minimizes profiled gas face wear due to loss of barrier fluid
Seal transitions to a contacting wet mode during gas disruptions for greater sealing reliability
In-Gland Control System (IGCS) dynamically tracks process pressure to minimize gas consumption
Non-fretting to equipment
No heat generation​
