AS-BAI to replace AES BSAI metal bellow seal.

This type is a perfect replacement of AES BSAI metal bellow seal.This type is available in a wide range of seal face and elastomer combinations, together with self-aligning, DIN, T, L shaped or boot mounted stationaries.

Features:
Short working length 
Suitable for limited space applications
Hydraulically balanced for reduced seal face loading, which maximizes seal life and allows for vacuum service capability
Graphite packing comes with excellent chemical resistance
Sizes are available from 1.000"to 5.000"(24mm - 125mm)

Background Knowledge：
What are the advantages of welded metal bellows mechanical seals compared with other mechanical seals?
The welded metal bellows mechanical seal has good floatability and random compensation, which can compensate for the leakage of the seal ring due to wear, axial movement and vibration. The welded metal bellows itself acts as both an elastic element and a seal, so there is no need to design the dynamic auxiliary sealing ring of the conventional pusher-type mechanical seal, thereby avoiding the blockage of fine particles caused by the dynamic auxiliary sealing ring，which is not resistant to high temperature and has the problem of reducing the compensation ability of the seal due to the axial frictional resistance.
