Mechanical Seals, Seal Support Systems and More for the Chemical Industry | John Crane

Chemical

Though the wide range of equipment required by the chemical industry poses a challenge, it’s one well met by John Crane. We have hands-on experience with virtually every style and standard of rotating equipment, and we’ve developed a broad range of solutions with proven application success:

  • Cartridge seals and support systems that meet global standards
  • Products for use on non-metallic or glass-coated equipment
  • Seals in exotic alloys that accommodate highly corrosive and abrasive applications
  • Innovative filtration of process flow to ensure required process purity
  • ATEX-compliant
  • FDA-recognized seal faces and elastomers

Plus, our 200 global rapid-response facilities ensure that our chemical industry customers are never far from service, repair or support.

A History of Innovation

Our dedication to innovative applied engineering is reflected in both our technology and our product range. In 1993, we built the industry’s most advanced testing center to qualify designs to the API 682 specification. Since then, we’ve also developed cartridge seals that are modular and those that provide zero-emissions operations. We’re committed to maintaining our position at the forefront of innovation and meeting our customers evolving needs through ongoing research and development.
