A development project sponsored by the Department of Energy’s Industrial Technologies Program (ITP, www1.eere.energy.gov/industry/about/) resulted in a new Ultrananocrystalline Diamond (UNCD®) solution for use in rotating pump and gas seal applications. According to ITP, UNCD offers a unique diamond thin-film microstructure that provides superior low-friction, corrosion- and wear-resistance when used in mechanical seal environments. The technology, which won a Wall Street Journal Technology Innovation award in 2006, is now being commercially applied on industrial rotating pump and gas seal applications by Advanced Diamond Technologies (www.thindiamond.com), the exclusive licensee to the UNCD technology. The ITP-sponsored project was developed in partnership with Argonne National Laboratory (www.anl.gov). ITP says UNCD can help optimize energy efficiency by reducing pump shaft frictional torque by as much as 75 percent.
