The BT-C8 mechanical seal range is designed for universal 

application and is ideally suited for standardization. 

The seal is bi-directional, unaffected by the direction of 

shaft rotation and is positively driven by set screws. With 

super-sinus spring. The advantages of this mechanical seal 

are the easily interchangeable seal faces which permit all 

material combinations.

Features
