Operating Parameters
● Pressure: ≤2MPa ● Temperature: -60~200℃ ● Shaft Diameter: 25~360mm ● Speed: ≤15000r/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. ● The two groups of seal are arranged back to back. ● Zero leakage of process gas can be achieved, and trace nitrogen will leak into the  body and enter the process system. ● Unidirectional grooves and bidirectional grooves are available. ● Cartridge design is easy for installation and dismantling. ● Suitable for low pressure and process gas quality is poor, toxic, harmful, corrosive  occasions.
Recommended Applications
● Gas Screw Compressor ● Heat Pump Screw Compressor ● Flare Gas Screw Compressor ● Regas Screw Compressor ● Waste Gas Screw Compressor ● Coke Oven Gas Screw Compressor
Interface Details
● A Buffer Gas      Nitrogen/From compressor discharge, nitrogen is preferred ● B Seal Gas      Nitrogen/Other inert gases, nitrogen is preferred ● C Leakage Gas     Vent to safe lacation ● D Separation Gas   Nitrogen/Instrument air, nitrogen is Preferred
