- Precisions：All Deublin seals are micro lapped to an optical flatness within 2 light bands or 0.000023" utilizing proprietary lapping machinery and compounds.
- Balanced Mechanical Seal：With this technology, the thrust load or seal face contact pressure is kept to a minimum regardless of media pressure. This reduces wear, resulting in longer seal life.
- Extended Life Sealing：E.L.S. rotating unions offer outstanding performance under the toughest conditions, and can extend service life two to four times, depending on the severity of the application.
- Number System：DEUBLIN ordering numbers for standard rotating unions consist of 2, 3 or 4 number groups. Each group describes a particular characteristic feature such as application, seal combination or rotor connection.
- Global Professional Service：We have a worldwide service network consisting of whollyowned subsidiaries and authorized distribution network. Whether you need a spare part, a new product, technical advice, or help with an ongoing design project, our experienced customer service representatives and engineers are always available to provide immediate assistance.
