Double end dry gas seal
Applicable Scope
Temperature:-40~260℃；
Pressure: P≤1MPa；
Linear Speed: V≤150m/s；
Application Fields: Catalysis or coking rich gas compressor in petroleum refining process, desorbed gas compressor and so on.
Design Feature
Applies to dangerous gas which mustn't be leaked into atmosphere,at the same time,little seal gas going into process is permissible;
Between two sets of sealing faces,0.2～0.3MPa higher pressure sealing gas is
injected,the leakage of seal gas goes into the process and atmosphere.therefore,the process gas will never leak out into atmosphere:
The rotating ring floats axially,therefore it has good adaptability.
