Espey chamber seals have a modular design which means the seals can be composed using standard parts to meet individual application requirements. Espey chamber seals work with a very small operation gap between shaft and seal ring – leading to very low leakage – and are designed for dry-running and compensate radial and axial shaft deflections. Another advantage is that no sealing components which could generate additional shaft vibrations are actually fitted on the shaft. The seal rings are axially spring-loaded to prevent swinging up at pressure-less machine operation.

Espey chamber seals are applied in several turbo machines: integral gear, screw and chiller compressors, steam turbines, and shut-off valves for power plants. The main industries in which it is implemented are oil and gas, refining, chemical and petrochemical industry, power plants, and plants for iron and steel production.
