3. Corrosion resistance: the core components of pump case, rotor and side cover are made of integral anti-corrosion alloy. It can be used under the conditions of organic acid, carbonic acid, nitric acid, sulfuric acid and hydrochloric acid.

Anti-corrosion materials:

A. High grade spheroidal graphite cast steel surface infiltration hardener + Ni plating

B. 316L and super stainless steel materials

C. TA, TC and other series of titanium alloy materials.

D. Cast steel parts + lining engineering plastics.
