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.
Chemical Application Products
Specialized applications such as aggressive acids, dewatering chemicals and high-pressure, high-speed polymerizing fluids require extensive materials research and proven designs. John Crane products are specifically developed to meet the unique needs of customers in the chemical processing industry.
