Parallel Spring Balanced Diaphragm Mechanical Seals

Parallel Spring Balanced Diaphragm Mechanical Seals - Design Advantages

Experience the cutting-edge performance of our A1 to A5 range, the ultimate combination of elastomeric bellows and bi-directional parallel spring seals. Engineered with superior face materials and patented design features, these seals redefine excellence in sealing technology.

Our innovative solution eliminates failures caused by excessive wear from thinner components by ensuring unmatched durability. By increasing the drive area by over 250%, we have significantly reduced contact drive pressure and subsequent wear. The drive ring is also securely retained by a locking mechanism, providing added stability and reliability.

This range is hydraulically balanced, resulting in reduced heat and friction during operation, enabling higher operating parameters, increasing the performance and life capability of the seal, in comparison to the market standard unbalanced alternatives. To further enhance reliability, an additional drive ring supports the lip, ensuring the drive ring remains in a positive position away from the bellows.


For Vulcan Seas Types A2 to A5, we offer the convenience of retaining the base plates on the coil, providing vital support during seal fitting.

  • Superior design and performance
  • Reliable seal face retention
  • Refined fit for both imperial and metric shaft sizes
  • Unlike standard market metric designs, Vulcan Seals are specifically designed for imperial or metric shafts
  • Optimised face loading gives increased seal life
