Dry gas seals replacement to: 
John Crane: 2800E, 28VL, 2800
Burgmann: CGS-KN, CGS-KD. 

Our mechanical seals have been widely applied to Petroleum, Chemical fiber, Fertilizer, Oil refining, Papermaking, Nuclear power, Power plant, Metallurgy, Food, Pharmaceuticals, etc. Main products are mechanical seal, dry gas seal, metal bellow seal, mixer seal, cartridge seal and all kinds of seal control systems, applying to rotating equipments.
 
Our seals are interchangeable with John Crane, Burgmann, AES, Flowserve, Fluiten, Roten, Sealtek etc.
Here is some reference.
 





seal faces are non-contacting during running.
Groove choice has bidirectional rotation and unidirectional rotation.
cartridge design makes installation and removal easy;
For neutral medium without pollution to the environment;
Typical Applications: Nitrogen compressors, air compressors, CO2 compressors, high-speed multi-shaft compressors.

Three Different Arrangements:
Single Face
Especially for non-toxic harmless gas, such as air, N2, CO2 and so on,in order to save the nitrogen, it is generally fixed
with the carbon ring seal as tandem seal

Double Face
The dual face seal working performance is similar to that of GS100, but with higher anti-pressure ability.

Tandem
The contact mechanical seal will be the main seal and the gas seal will be the stand-by seal. When the main seal fails,
the standby seal takes the work immediately to prevent the occurrence of leakage. This application solution is mainly
designed for volatile media, such as light hydrocarbons.
