pneumatic sealing device
- June 11, 2019
The Orion Engineered Seals pneumatic sealing device (PSD) is an engineered pneumatic sealing system designed to seal the shafts of machines where typical contact seals such as packing and/or mechanical face seals prove to be too costly to operate and maintain.
PSD Sealing system features:
- Efficient design minimizes air usage while maintaining internal sealing pressure profile
- Resilient to angular and parallel shaft movement
- Pressures /temperatures to 120psi/575oF
- Split seals available in most designs
- Wide range of materials available covering most application requirements
- Requires little or no maintenance after installation
How the Pneumatic Sealing Device Works
The pressure profile forms a circumferential boundary layer internally that mitigates the effects of shaft movement because
