The 108 series mechanical seal is widely used. The structure uses rubber bellows as a secondary seal and transmits torque force. Through the double compensation ring back-to-back pair, it can become a 208 seal with reliable performance. Pipe pumps, submersible pumps, etc.

In the initial development and design of any product, we follow the standardization of installation dimensions. That is, the installation rule of this type of mechanical seal is in accordance with international and domestic standards (API610, API682, DIN24960, ISO3069, GB6556).

The 108 series mechanical seal is highly interactive and widely used. The rubber bellows is used as the secondary seal, which also transmits the torque force, and can form a 208 mechanical seal when back-to-back is formed by double compensation rings. Reliable performance. Widely used in IR hot water pump, submersible pump, pipeline pump, centrifugal pump, IS fresh water pump ...

Installation dimensions comply with API610, API682, DIN24960, ISO3069, GB6556 standards.
