John Crane, a global leader in rotating equipment solutions, supplying engineered technologies and services to process industries, today announced that as of April 17, 2019, the company finalized its purchase of the Industrial Division of Advanced Diamond Technologies (ADT).

ADT, based in Romeoville, Illinois, is a leader in the development and application of diamond films for industrial, electronic, mechanical and medical applications.

“John Crane’s acquisition of the Industrial Division of ADT underscores our commitment to technology as a key driver of strategic growth,” said Jean Vernet, President and CEO of John Crane. “ADT has built an impressive business based on a unique and superior diamond facing process, making this acquisition a step in further enhancing our industry leadership. This technology will result in improved  performance and reliability for mechanical seals under harsh conditions in pumps and other industrial applications, bringing important benefits to our customers.”

The Industrial Division of ADT developed unrivaled expertise in proprietary materials that capture the properties of natural diamond using chemical vapor deposition. Broadly referred to as ultrananocrystalline diamond (UNCD®) technology, this product is a thin-film diamond material grown through a proprietary chemical vapor deposition process.

UNCD® improves mechanical seal reliability and performance in difficult applications involving poor lubricating fluids, liquids above their atmospheric boiling point and abrasive slurries. In addition, UNCD® has a low coefficient of friction which results in lower heat generation and energy consumption.
