Anhydrous sulfuric acid solution, operating temperature of 120–130°C, with a sulfuric acid content of 15–20%. The crystals in this solution are in the form of very small particles. Our mechanical seals leak frequently during use; could you recommend a chemical pump for this application?

Double-end face seal with oil-cooled circulation

The mechanical seal is caused by liquid crystalline particles, right? If there are particles, it is recommended to consult a positive displacement pump

The brands and types of mechanical seals used for KSB pumps are quite specialized

At high temperatures, generally, 15-20% aqueous solutions of sulfuric acid do not contain crystalline particles; is it due to the high temperature? I think

The temperature isn’t that high, right? Hot water is still at 100 degrees
