The submerged pump conveying concentrated sulfuric acid usually needs to use corrosion-resistant materials, and the choice of specific materials depends on the parameters such as concentration, temperature and pressure of concentrated sulfuric acid, as well as the structure and use of the submerged pump.

The following are some commonly used corrosion-resistant materials for your reference:

Fluoropolymer: Fluoropolymer is a material with excellent corrosion resistance, which can resist the corrosion of concentrated sulfuric acid. Commonly used fluoroplastic materials are PTFE (polytetrafluoroethylene), PVC (polyvinyl chloride) and PVDF (polyvinylidene fluoride).

Stainless steel: Stainless steel is a material with strong corrosion resistance, which can resist the corrosion of concentrated sulfuric acid. Commonly used stainless steel materials are 304, 3 16, 3 16L, etc.

FRP: FRP is a kind of material with good corrosion resistance, which can resist the corrosion of concentrated sulfuric acid with a certain concentration. However, the strength of FRP is low and it can't bear high concentration of concentrated sulfuric acid.

Nickel-based alloy: Nickel-based alloy is a kind of material with good corrosion resistance and can resist the corrosion of concentrated sulfuric acid. Commonly used nickel-based alloy materials are Monel alloy and Hastelloy alloy.

It should be noted that different materials have different corrosion resistance and physical properties, so it is necessary to choose the material of submersible pump according to the actual situation. In addition, in order to ensure safety, manufacturers and brands with relevant qualifications and certifications should be selected and used and maintained in strict accordance with operating procedures.
