The influence of medium properties on the selection of chemical pumps —— medium composition, concentration, temperature

Thread Content

When choosing a corrosion-resistant pump, it’s far from enough to only know that there is corrosion present! When chemical pumps are used to transport chemical media, factors such as the composition of the medium, its temperature, concentration, toxicity, solid content, and viscosity are key considerations in selecting the appropriate material. Among these, the composition, concentration, and temperature of the medium not only directly affect the corrosion resistance of the material, but also indirectly influence the corrosion rate and type by altering physical properties such as viscosity, electrical conductivity, and reactivity, thereby determining the economic viability and safety of the material choice. Even for corrosive media, changes in composition, concentration levels, or temperature can result in vastly different corrosion-resistant materials being suitable for use Selection of sulfuric acid at different concentrations and temperatures: Selection of sodium hydroxide at different concentrations and temperatures:
