Operating Parameters
● Pressure: ≤4MPa ● 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 of pairs are arranged back-to-back. ● The surrounding design for seat effectively reduces the damage of equipment which 　caused by broken seat. ● Zero leakage of process gas can be realized, and a trace amount of nitrogen will leak 　into the body into the process system. ● Unidirectional grooves and bidirectional grooves are available. ● Cartridge design is easy for installation and dismantling. ● It is suitable for low pressure and poor process gas quality, toxic, harmful and corrosive 　occasions.
Recommended Applications
● Rich Gas Compressor ● Flare Gas Compressor ● De-adsorption Gas Compressor
Interface Details
● A　Buffer Gas 　　　 　Nitrogen/Process gas, nitrogen is preferred ● B　Seal Gas 　　　　　Nitrogen/Another inert gas, nitrogen is preferred ● C　Leakage 　　　 　　Vent to safe location ● D　Separation Gas　　 Nitrogen/Instrument air, nitrogen is preferred
