Based on an evolution of more than 30 years of compressor sealing solutions, our separation seals are comprised of contacting bushings, non-contacting bushings and labyrinths. These meet the latest industrial standard API 692 and protect the dry gas seal from oil ingress, maintain sealing integrity in the event of a dry gas seal failure, reduce maintenance costs and improve reliability. When it comes to keeping your rotational equipment running 24/7, John Crane’s comprehensive range of separation seals have you covered.
