Operating Parameters
● Pressure: ≤10MPa ● Temperature: -60~200℃ ● Shaft Diameter: 25~270mm ● Speed: ≤50000r/min ● Linear Velocity: ≤180m/s The above limit application parameters are not met simultaneously, customized design for particular applications.
Product Description
● Non-contact running seal face. ● Two sets tandem frictional pairs, the primary seal is for main seal, the secondary seal is 　for safe seal. ● The surrounding design for seat effectively reduces the damage of equipment which 　caused by broken seat. ● Process gas does not leak into the atmosphere, and external nitrogen does not enter 　the process system. ● The two-stage seal can withstand the full process pressure, and after the failure of 　inboard seal, outboard seal can still operate safely under the full process pressure. ● Unidirectional grooves and bidirectional grooves are available. ● Cartridge design is easy for installation and dismantling. ● Suitable for most applications, it is a structure with the highest safety and reliability.
Recommended Applications
● Cracking Gas Compressor ● Propylene Compressor ● Ethylene Compressor ● Natural Gas Compressor ● Recycle Hydrogen Compressor ● Recycle Gas Compressor ● Ammonia Compressor ● Expander
