• Dual seal pressurized with an inert gas barrier operates with zero process emissions to satisfy environmentalmonitoring 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.
• Factory preset and tested cartridge design simplifies installation on the equipment for a quick and trouble-free start-up.
• Gas barrier sustained by a Plan 74 support system is simple to operate and reduces the maintenance, costs, and complexity associated with liquid barrier systems.
