Material selection for concentrated sulfuric acid pumps
Thread Content
What materials are used for components such as the pump, casing, and impeller of a 98% concentrated sulfuric acid transfer pump? Will carbon steel work?
Theoretically, there is no problem with carbon steel; it will be fine as long as it is used and maintained properly. If horizontal use is not feasible, it can be troublesome as residual sulfuric acid absorbs moisture and causes corrosion; if the flow rate and pressure are low, plastic ones can be used
Anything will do; just use whatever is available on the market. Do you plan to buy plastic and make the pump yourself? Just check Alibaba to see what types of plastic pumps are available for sale
It is better to use PFA pumps, as carbon steel poses too many risks. Carbon steel can indeed be used for concentrated sulfuric acid storage tanks
High-silicon iron pumps are very useful and durable
Using ordinary carbon steel won’t work; don’t rely on theory – there are too many unexpected situations in practical applications, and it just doesn’t work
For PTFE, 316L is also fine if there are few impurities
What model of pump is the high-silicon ferro pump?
