How Non-Contacting Seal Technology
The seals are enhanced to alter the primary seal interface lubrication, which allows the seal to operate within the non-contacting regime.
Qualiseal designs features for the face of the mating ring, the ring rotates, and the features force fluid (air, gas) into a converging gap in the sealing face—the pressure increases between the primary sealing elements. As the pressure builds, the faces separate, hence the part operates in a non-contacting mode.
The seal design incorporates a static sealing dam that prevents leakage when the part is not rotating. The pressure generated between the faces is greater than the system pressure, which causes the mechanical face seal to leak air into the system instead of fluid out—this type of mechanical seal results in reduced friction and increased surface speed.
Why Use Non-Contacting Sealing Technology?
Non-contact rotating seals provide many benefits, such as:
- Little to no wear
- Significant decrease in friction and heat generation
- Potential zero leakage
- Better performance with a greater life expectancy
- Saved time and resources – no oil jetting, coatings, or particulate issues
- Fits into the same space as a traditional contacting seal
It is common to condense our sealing solution into small/lightweight packages and conditions like those required in the aerospace market. Our expertise gives us the know-how to solve complex industrial problems. Typical aerospace applications run from 15,000-80,000 RPM or 500 ft/sec. We have the capability to meet speed requirements for the most stringent industrial applications.
