Is the mechanical seal of the feed water pump of Changsha secondary high pressure boiler good? Or is it better to seal the package?

The particularity of boiler feed water pump is that the medium is high temperature and high pressure water. Because the lubricity of water is not as good as that of other media, the requirement for mechanical seal is higher.

As for the sealing material, we mainly consider the material of the dynamic and static ring and the material of the O-ring.

I recommend John Crane's 8BVS seal to you, which is an engineering seal specially designed for boiler feed water pump. In addition, John Crane's RREP seal can also be used in this working condition.

As for packing, it is not recommended. Once high temperature and high pressure water leaks into the atmosphere, it is still very dangerous for operators. Safety first! ! !
