What pump should be used for transporting concentrated sulfuric acid (93%~98%)? Last edited by flyyi61 on 2009-2-2 13:29]
It seems that the fluoroplastic magnetic pump (lined with PFA) is the most suitable.
For concentrated sulfuric acid, different carbon steel shielded pumps can be used.
We used fluoroplastic pumps before, but now we have switched to magnetic pumps. Actually, fluoroplastic pumps would be better, because in winter when the temperature is low and there are solid particles in the sulfuric acid, it can easily cause damage to magnetic pumps
Personally, I think the suggestion for the fourth floor is the most appropriate, but it is also necessary to analyze it based on the specific environment and manufacturing processes
If the temperature is not high, a pump made of carbon steel will suffice. If the temperature is relatively high, it is recommended to use a corrosion-resistant lined pump.
A corrosion-resistant pump will do; it’s a high concentration, no problem
For pumping concentrated sulfuric acid, fluoroplastic magnetic pumps are the preferred choice. Mechanical seal pumps will start to leak after about five to six months of use when transporting concentrated sulfuric acid, which is quite troublesome.
