Shaft seal SDK40 STASSKOL

Possible Applications

This specialized shaft seal is deployed primarily in high-pressure reciprocating compressors handling hazardous, toxic, or valuable gases within petrochemical refineries and synthetic ammonia production plants. Because hypercritical rotors operate under extreme pressure differentials and high rotational velocities, conventional rubbing seals experience rapid thermal degradation and excessive wear. The contact-free labyrinth design of this component prevents mechanical friction during continuous operation, making it ideal for processes requiring ultra-low fugitive emissions and prolonged mean time between failures. Consequently, it is heavily relied upon in high-pressure polyethylene synthesis loops and hydrogen booster stations where gas containment integrity and process reliability are critical.
