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.
