On the static electricity issue of impellers in fluoropolymer magnetic pump systems
Thread Content
Previously, IHF fluoropolymer pumps were used to transport benzene, which is flammable, explosive, and acidic due to hydrochloric acid. IHF pumps present a significant safety risk because their mechanical seals tend to leak. Now, we want to switch to magnetic pumps, but a new problem has arisen: friction between the liquid and the impeller definitely generates static electricity, but how can this static electricity be discharged? How can static electricity on the impeller be eliminated? The manufacturer recommends replacing the rear cover of the IMD magnetic pump with a material resistant to corrosion. However, both stainless steel and titanium alloys have been tested for corrosion resistance, and neither works well; Hastelloy is too expensive ； Urgent help needed – experts, both new and experienced, please assist!
You can just use a magnetic pump made of fluoroplastic alloy.
Reinforced with carbon fiber, and conductive by itself. There is no problem in transporting ultra-pure water.
Conductivity must be taken into account; the component that experiences overcurrent must be made of metal, as carbon fiber does not provide an adequate reinforcing effect.
