What material is good for chlorine sulfonic acid unloading pumps?
Thread Content
I’m seeking advice from experts: what material is suitable for use in pumps used to unload chlorosulfonic acid? Our company uses the QCY80-250 submersible pump manufactured by Qingdao Hengbang. A leak occurred in one of these pumps after it was used to transfer a batch of material, so we need to select a different model. I would appreciate any suggestions from everyone; thank you!
It is better to use a lined pump; if a metal pump is to be used, materials such as Hastelloy that are of higher quality may be required, resulting in higher equipment costs.
Given the special nature of the medium, conventional centrifugal pumps carry a risk of leakage; it is recommended to use leak-free pumps, magnetic drive pumps, or shielded pumps
Fluorine-lined; a diaphragm pump can be considered for unloading
Magnetic pump, power-sealed pump, pneumatic diaphragm pump, and the like can all be used
When using a fluorine-lined magnetic pump, an explosion-proof motor must be used
Fluorinated magnetic pump or PVDF pneumatic diaphragm pump
It is better to use fully fluorinated materials; both centrifugal pumps and diaphragm pumps work well
