Laminar Configuration
QSD Series configuration consists of 2, 2-Turn laminar seal rings (FEY Rings) that cling to a shaft. When an environment has excess contamination or an application requires additional protection, laminar seal rings may be used in combination to form an additional seal. This application doubles-up the QSD ring arrangement by incorporating a second set of rings in a secondary groove. To further the sealing effect, this connector has a third ring installed that creates an additional labyrinth.
Application
Connector The seal arrangement in this assembly has been custom designed for optimum protection against contamination. Gases build up pressure in a center cavity, protected on both ends from contaminants entering. Assurance has been built into the design so gases are clean as they enter and exit the center cavity.
Environment
High contamination: small particles and gases.
