S718 Single Dry Gas Seal for Centrifugal Compressor

Operating Parameters
● Pressure: ≤25MPa ● Temperature: -160~260℃ ● Shaft Diameter: 25~360mm ● Speed: ≤50000r/min ● Linear Velocity: ≤180m/s The above limit application parameters are not met simultaneously, customized design for particular applications.
Product Description
● Suitable for high pressure, large shaft diameters and demanding applications. ● Non-contact running seal face. ● The pair is arranged in a single stage and has compact axial dimensions. ● The surrounding design for seat effectively reduces the damage of equipment which caused by broken  seat. ● The auxiliary seal uses high-performance polymer seal which has good temperature resistance, pressure  resistance, and corrosion resistance. ● Unidirectional grooves and bidirectional grooves are available. ● Cartridge design is easy for installation and dismantling. ● It is suitable for occasions where the process medium is allowed to leak into the atmosphere.
Interface Details
● A Seal Gas      Process gas/External gas ● B Leakage Gas     Vent to flare/Vent to safe location ● C Separation Gas   Nitrogen/Instrument air, nitrogen is preferred
Recommended Applications
● Nitrogen Compressor ● Air Compressor ● Supercritical CO2 Compressor/Expander ● Multi-shaft Gear Compressor ● CO2 Compressor
