General Service Metal Bellows Seals

• Metal Bellows seals can seal with Flexible Graphite instead of a rubber boot or o-ring Elastomers allowing it to be used in higher temperature
  applications
• No Springs to clog!!!!!
• Metal Bellows seals are a very effective method of maintaining seal
  face pressure on the seal face.
• Metal Bellows seals that do use o-rings only require one static o-ring
  to seal off any leakage along the shaft in Chemical Service this o-ring
  will be PTFE.

An alternative to using multi-spring seals is a metal bellows seal with a singular o-ring. Because the o-ring is static it will not wear on the shaft. When installed correctly metal bellows seals will provide exceptionally long service. Metal bellows seals are an excellent solution on chemical applications where Kalrez, Chemrez, Viton, FKM, Buna, Aflas, or EPDM are not compatible.

For many years an inexpensive form of metal bellows seals has been used very successfully in the wastewater/sewage industry and in the agricultural fields pumping irrigation water. These seals were generally made of a metal formed bellows rather than a welded bellows. Welded bellows seals are much stronger and have superior flex and recovery characteristics which are more ideal to holding seal faces together but cost more to manufacture. Welded metal bellows seals are less prone to metal fatigue and are available in single and double-ply.

American Seal & Packing has negotiated the production of welded metal seals made for us at a cost similar to formed bellows. As a result, we can offer welded metal seals that will last longer in the field resulting in less pump downtime, less loss production and fewer labor costs, saving you incalculably.

Of course, none of this would be attainable if the quality system was not ensuring consistent, repeatable, quality. Manufactured under an ISO-90001 system, maintaining the quality of the materials, and workmanship. On receipt of the product, the seals are re-inspected, labeled, and packaged.

We offer both:

1. General to sever application elastomerically sealed metal bellows seals.
2. High temperature seals for over 500 F applications.
