What kind of pump is suitable for strong acids and strong bases? It is about 35% sulfuric acid; is FRPP material or PVDF material more suitable?

We use Ewichi pumps here, they’re Japanese-made and really effective.

PP is fine; fluoroplastics are even better. Such as PVDF, ETFE, PFA

At 35%, PP is also acceptable; of course, PVDF is better, while ETFE and FEP are even better

Fluoroplastics would be better; stainless steel is not suitable for sulfuric acid
