The BT-FN combines a spring loaded ceramic seal     

face and the traditional pusher mechanical seals.     

The competitive price and the wide range of applications     

have made the BT-FN seal a success. The seal is     

produced with punched metal parts that allow an     

economical design.     

BT-FN mechanical seals are also the ideal solution for light     

chemicals media applications. To ensure the best reliable     

performance, we recommend a material combination of     

hard material sliding faces and proper elastomer O-Rings.
