A rotating union must be capable of containing high pressures while
rotating at very high speeds.Smooth,easy rotation can only be
achieved by exactly mating the seal faces to minimize friction.
Precision and tight tolerances are critical in the micro lapping of sea
faces.All Deublin seals are micro lapped to an optical flatness within
2 light bands or 0.000023”utilizing proprietary lapping machinery
and compounds.This level of precision is essential for dependable
leak-proof operation.
Housings are machined on multi-axis twin-spindle lathes to obtain the
necessary part-to-part precision.Rotors and other parts are turned
on automatic bar machines to ensure true-running rotating unions
without any wobble.This assures extended service life.
