Sulphuric Acid

Sulphuric acid is one of the most widespread of chemical fluids 


sulfuric acid is a powerful protonating and moderately strong oxidizing agent. These characteristics have a profound impact on the different materials that a pump is made of.


Material selection is key as the corrosive properties of sulphuric acid change quite dramatically depending upon its concentration and temperature.  Low concentrations can be resisted by arange of pump materials whereas medium concentrations require plastics such as PVDF and ETFE but when the concentrations get above 95% some stainless steels can be used once again.

AxFlow offer has a wide range of chemically resistant pump types suitable for pumping sulphuric acid and this includes 904 stainless steel which was specificially developed for use with stainless steel.
