Description
Balanced Stationary Multi-spring Dual 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.
Features
California Residents: Proposition 65 Warning
- 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 minimises asymmetric face distortions
