BSAI & BSAIG

The BSAI range is available in a wide range of seal face and elastomer combinations, together with self-aligning, DIN, CURC , T, L shaped or boot mounted stationaries.

Features:

• Short working length suitable for BSEN 12756 (formerly DIN 24960) housings
• Suitable for limited space applications
• Hydraulically balanced for reduced seal face loading, which maximizes seal life and allows for vacuum service capability
• BSAIG features graphite packing with excellent chemical resistance
• Sizes available from 1.000″ to 5.000″ (24mm – 125mm)

BSAI Metal Bellows Component Seal

The main benefit of using a metal bellows seal is the removal of the semi-dynamic sliding elastomer from a conventional pusher type seal. This means that bellows seals can be used where chemical attack on this elastomer is a problem.

Major advantages of using AESSEAL® Metal Bellows Seals

• 50% more bellows than the industry standard means there is less stress on each convolution in the bellows stack which helps
increase seal life. It is for this reason that this seal is more able to accommodate installation tolerances and will maintain a more
consistent face pressure as the seal wears in use
• Finite Element Analysis was used to optimise the bellows convolution profile on its inside diameter at 45º which means minimal stress
on the weld beads
• The standard bellows material, Alloy 276, has superior mechanical and corrosion resistance properties compared to other
industry standard bellows materials such as 300 series Stainless Steel or Alloy 20. The seal face holder and drive end are
inventoried as standard in 316L Stainless Steel
