Rotary Part Of Customized Metal Bellow Mechanical Seal AS-B231

Background Knowledge：
The requirements of mechanical seals for sealing materials are generally as follows :

1) The material should have good compactness and it is not easy to let the medium leak;

2) Have appropriate mechanical strength and hardness;

3) Good compressibility and resilience, small permanent deformation;

4) No softening or decomposition at high temperature, no hardening or brittle cracking at low temperature;

5) Good corrosion resistance, can work for a long time in acid, alkali, oil and other media, the volume and hardness of the pump where the mechanical seal is installed will change little, and do not adhere to the metal surface;

6) Small friction coefficient and good wear resistance;

7) It has the flexibility to combine with the sealing surface;

8) Good aging resistance and durable;

9) It is easy to manufacture the materials and easy to obtain cheap materials.
