Acid and alkali resistant chemical pumps in the selection of what to pay attention to?

　　Acid and alkali chemical pumps, is a special material made of a special equipment, with strong corrosion resistance, large flow, high head, compact structure and other characteristics, is a large chemical plant equipment, but also an important part of a variety of petrochemical equipment, therefore, in the acid and alkali chemical pumps selection, you need to pay extra attention to the acid and alkali resistance of these pumps to ensure that they are reliable and service life.

　　Acid and alkali chemical pumps in the selection of what to pay attention to

　　First of all, in the selection of acid and alkali chemical pumps, according to the needs of a comprehensive assessment of its acid and alkali resistance, mainly acid and alkali resistance performance indicators, heat resistance performance indicators, abrasion resistance performance indicators, corrosion resistance performance indicators and corrosion resistance and stability performance indicators, etc., which are the key indicators to test the pump's acid and alkali resistance, must be considered comprehensively in order to ensure that the pump's reliability and service life.

　　Secondly, we should consider the maximum material temperature that the pump can withstand, because the higher the temperature, the worse the pump's acid and alkali resistance, and will accelerate the corrosion of the pump material, affecting the service life. Therefore, when purchasing acid and alkali resistant industrial pumps, the highest material temperature must be considered to ensure the reliability and service life of the pump.

　　Again, when considering the acid and alkali resistance properties of chemical pumps, it is also necessary to consider the corrosion resistance of the pump body as well as other components. The acid and alkali resistance characteristics of the pump not only depends on the pump body material, but also depends on the corrosion resistance of other parts of the pump, for example, seals, threads or wear parts. Therefore, in the selection, we should pay attention to consider the corrosion resistance of these parts to ensure the service life of the pump.

　　Finally, when selecting acid and alkali resistant chemical pumps, it is necessary to consider its structural dimensions to ensure that it can meet the requirements of actual use. The structural dimensions of the pump will not only affect the flow and head of the pump, but also affect the acid and alkali resistance of the pump. Therefore, in the selection, must consider the structure of the pump size, to ensure that the pump can meet the requirements of the actual use.

　　In summary, when selecting acid and alkali chemical pumps, the acid and alkali resistance characteristics of the pump, the maximum material temperature, corrosion resistance and structural dimensions should be considered to ensure the reliability and service life of the pump.
