Product Description

AKM-BT-FN
Structure Description:
 

Features

• Single pusher-type seal
• Unbalanced
• Conical spring
• Dependent on direction of rotation

Advantages

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.
