Selection of a concentrated sulfuric acid transfer pump for 98?
Thread Content
Would it be a good idea to use a magnetically driven pump for transporting concentrated sulfuric acid at 98% concentration? Which domestic manufacturers produce reliable magnetic drive pumps?
A fluorine-lined magnetic pump can be used; make sure to select a motor with sufficient power. The manufacturer can be contacted through the details in my signature
Cast iron will do, right? This concentration will cause passivation
We have an alkylation process here; the sulfuric acid concentration is basically 98%. I’m not quite sure what type of material is used – it seems to be a centrifugal pump. You can look up information on alkylation processes; maybe you’ll find what you need
For concentrated sulfuric acid, the material of choice is mainly cast iron; the specific selection depends on the operating parameters provided by the client.
