Mechanical Seal with stationary springs, rotating seal
- Single seal
- Balanced
- Independent of direction of rotation
The new stationary mechanical seal 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
