Hydrodynamic non-contacting lift-off face seals
Featured Product from Technetics Group
HYDRODYNAMIC MECHANICAL SEALS AND EDGE-WELDED METAL BELLOWS
In critical use-cases, like aerospace, where a typical contacting seal is not an option, Technetics Qualiseal® hydrodynamic non-contacting lift-off face seals are a superior alternative. While other non-contacting seals fail due to the changes in altitude, Technetics’ Qualiseal® hydrodynamic lift-off seals maintain a consistently stiff air film throughout each operating condition. The unique geometric features designed into the rotor grooves create a pumping action to maintain separation from the seal. We manufacture and test each sealing system in-house.
Technetics also offers a mechanical seal incorporating edge-welded metal bellows that provide superior stroke capabilities and precise spring rates. This design ensures that the force balance equation stays consistent as the seal ascends altitude and runs through various operating conditions. Technetics optimizes our mechanical seals’ engineering design and manufacturing for even the most critical customer applications.
