What are the well-known brands? Who has used them?
The poster's statement may be an isolated phenomenon, but it seems to have no theoretical basis.
Want to buy famous brands. Because phosphorus trichloride is corrosive and dense. High requirements for shaft quality
The media characteristics of pcl3 need to be described, otherwise we will have to find information from scratch to help analyze it! I'm going to use a magnetic pump to transport AN soon, and I'm also scared!
Phosphorus trichloride is non-corrosive unless exposed to water vapor
We use a PP centrifugal pump to pump phosphorus trichloride, and there are no problems!
For magnetic pumps with PCL3, if you choose lining F, you can solve the corrosion problem... At least this is what we are currently using... There are two reasons for the shaft sleeve to break. One is that the medium contains large particles, causing the internal gap to be too small. The other is the problem of matching accuracy.
Damage to the magnetic pump shaft sleeve is generally caused by poor lubrication. It is recommended to check whether the material contains gas or generates gas. If there is, it will cause damage to the shaft sleeve due to poor self-flushing and lubrication.
