Model: BGMHRN-90
● Single Seal
● Independent of Direction of Rotation
● Balanced
● EN 12756 (DIN 24960)


The BGMHRN Series stationary mechanical seal for DIN installation spaces is ideal for use in dirty, abrasive media containing solids, e.g. in waste water systems and the chemicals industry. The stationary part has multiple springs and faces away from the product. It is thus protected from possible effects of the medium such as sticking and clogging. The seal is suitable for pressure reversals and can be operated in tandem as well as back-to-back arrangements. In vacuum mode there is no need for a separate stationary seat stop. No dynamically loaded O-ring on the shaft means there is no loading of the secondary seal by run-out caused by bending of the shaft. Distributed torque input and stationary seat locking by square pin.
