Bushing Seals: Principle: Injection of regulated high pressure oil between two
adjacent cylindrical white metal / aluminum lined
rings at each end of compressor
Config’s: - Single breakdown seals up to ~ 140 bar
- Double breakdown seals for higher pressures
Dry Gas Seals: Principle: Use cleaned & dried process gas at discharge
pressure bleeding across highly polished &
profiled radial faces separated by very small
clearances
Config’s: - Tandem seal with second stage as safety
back-up
- Triple seal required above 140 bar
