204B Mechanical seal

 

204B mechanical seal is mainly used in vertical reaction kettle, fermenter, stirring tank and tank containers. When the pressure is greater than 0.4MPa, a pressure balancing tank must be used. When the temperature is greater than 180 ° C, a cooling water tank must be installed. 204F and 204FF can be used for sealing reactors without liquid lubrication by selecting suitable friction pair materials, such as fermenter and seed tank. The 204FF is set to static ring pair for quick repair and replacement.

In the development and design of any product, we follow the principle of installation size standardization. That is, the installation size of this type of mechanical seal is in line with the domestic HG5-748-78 standard (referred to as 78 standard) and HG2098-91 standard (referred to as 91 standard).
