Type 8610
Manufacturer: John Crane
Balanced Stationary Multi spring Single Mechanical Seal
The seal is suited to a whole host of offshore, refinery and process industry duties. Its robust construction and proven heritage make it ideal for remote pipeline installations.
• Silicon carbide mating ring for high face stability and efficient heat dissipation
• Cranite primary ring for face stability and resistance to abrasion
• Optional ACR (Armoured Composite Ring) for high strength in reverse pressure operation
• John Crane Laserface® technology for increased fluid film stiffness and reduced heat generation under high loads
• ESR (Elastomer Support Ring) isolates seal faces from component induced distortions and minimise friction
• Stationary springs are unaffected by centrifugal forces for high speed operation
• Polymer Support Rings for excellent process compatibility and prevention of hang up
• Multi point injection for effective cooling and minimizes asymmetric face distortions
