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
