GAS BARRIER AND CONTAINMENT SEALS - GF-200

GF-200 dual seals are non-contacting, gas barrier seals used in applications where no emissions of hazardous pumped products can be tolerated. Advanced Pattern Groove System provides low speed lift-off, low gas leakage and no face contact.

Up to 35.4 bar (500 psi), -40 to 260°C (-40°F 500°F), up to 25 m/s (83.3 fps), 25.4 to 152 mm (1.000 to 6.000 inch)

Dual seal pressurized with an inert gas barrier operates with zero process emissions to satisfy environmental monitoring requirements

Silicon carbide seal faces use APGS Precision Face Topography to separate the faces with a stiff, thin gas film that prevents wear and extends seal life

The LoDragTM O-ring technology provides consistent dynamic O-ring squeeze to reduce drag and maintain proper seal face tracking

Seal faces are optimized by geometry, materials, spring loads, and drive mechanisms to remain flat under all operating conditions and deliver long-term, reliable performance

Non-contacting seal faces require very low power consumption during start-up and running operation
