April 18, 2019 | 1 minute read


We are excited to announce that Advanced Diamond Technologies (ADT), Industrial Division is now a part of John Crane!

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.

ADT UNCD Improving the performance of rotating equipment

UNCD-enhanced industrial components bring the chemical and structural properties of diamond to mechanical seals and hydrodynamic bearings used for rotary equipment, such as pumps and mixers. These properties enable equipment to achieve results that conventional alternatives cannot, enabling efficient and effective operation in even the harshest of application conditions.
