Specifically designed for steam turbines.

• High reliability with non-contact shaft seal exhibits near zero wear.
• Utilizes the steam from the turbine as a power source for the dynamic interposed gas film in the sealing surface.

• Temperature： -20 ~ 280℃ (-4 ~ 536 ℉ )
• Pressure： 0 ~ 14 kg/cm²G
• Surface Speed： 600 ~ 1,000 fpm
  
  

• Stationary Ring：Metal Carbon
• Rotary Ring：Hard Carbide
• Metal Parts：Titanium / Duplex / Inconel / CAP42
• Elastomeric O-rings：FFKM / SceniRAZ / Graphite
• Springs：Special Metal

• No contact of seal faces. In normal operation, seal faces separate and generate a sealing gap preventing friction and wear which prolong seal duration. 
• Low power consumption due to non-contacting faces. Seal faces generate significantly less heat and torque, and will not affect turbine's stability. 
• Self steam lubricated. Reacts sponteneously to maintain normal sealing gap.    
• Eco-friendly & Low Maintenance Cost. Near-zero vapor leakage, eliminates carbon rings usage and cost-down maintenance.
• Durable & reliable, relieved of turbine's bearing & oil steam contamination, maintaned clear & clean operating space.

• Designed for steam turbines.
