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. Supporting continuous uptime, John Crane’s separation seals are built for 24/7 performance in mission-critical rotating equipment.
How does a separation seal work?
A separation seal works by creating a barrier between lubrication oil and the dry gas seal. They are engineered to operate in extreme environments, preventing contamination, reducing wear and ensuring integrity.
