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.

Une histoire d’innovation

Notre dévouement à l’ingénierie appliquée innovante se reflète à la fois dans notre technologie et dans notre gamme de produits. En 1993, nous avons construit le centre d’essai le plus avancé du secteur pour qualifier les conceptions selon la spécification API 682. Depuis lors, nous avons également conçu des cartouches modulaires et celles qui permettent un fonctionnement sans émissions. Nous nous engageons à maintenir notre position à l’avant-garde de l’innovation et à répondre aux besoins évolutifs de nos clients par une recherche et un développement continu.
