Structural features:

The 203 type mechanical seal for the kettle is an external, single end face, and single spring balanced structure. Drive through the transmission sleeve. Due to the use of a single spring, it has good corrosion resistance and is not very sensitive to wear. Due to its balanced structure, it can withstand greater pressure than the 201 type, but the journal is limited to below 65mm. Suitable for sealing the stirring shaft of reaction vessels in the chemical industry.

Please select the friction pair material and auxiliary sealing material according to the actual working conditions.  

Scope of application:
Sealed medium: Different wear-resistant materials are selected to adapt to media with general corrosiveness or non corrosiveness.
Sealing chamber pressure: ≤ 0.25~0.6Mpa
Sealed chamber temperature: -40 ℃~200 ℃
Linear velocity: ≤ 5m/s
