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. ● The two stage seals adopt the same design, and can withstand full pressure, with high 　safety and reliability. ● There is no secondary seal gas (nitrogen) supply, and the secondary seal gas is from the 　primary seal gas leakage and a few process gas in secondary seal leakage will leak into 　the atmosphere. ● Unidirectional grooves and bidirectional grooves are available. ● Cartridge design is easy for installation and dismantling. ● It is suitable for the occasion that there is no nitrogen gas source on site or the leakage 　of process gas needs to be recovered.
Recommended Applications
● LNG Refrigerant Compressor ● Natural Gas Pipeline Compressor
