Sulfuric acid pump material
Thread Content
We need to use a high-pressure acid-resistant pump. Some suppliers say that at room temperature and with a concentration of less than 20%, a 316L material will suffice – is that okay?
That won’t work; 98% sulfuric acid is fine, but dilute sulfuric acid won’t do.
OP, isn’t the cost of choosing 316L too high? A fluorinated pump can be chosen; its corrosion resistance is excellent. Moreover, its cost is lower than that of 316L.
High pressure – how high must it be in order to determine whether fluorinated lining is effective or not? . .
Up to 75 bar, minimum 30 bar; those with fluorine lining are not suitable
316L won’t work; you can find corrosion manuals online – metals in dilute acids are not suitable.
75 kilograms, can’t do it? That shouldn’t be the case
