Acid-and alkali-resistant pumps are suitable for a wide range of areas, such as metallurgy, electric power, paper, food, pharmaceutical, synthetic fiber and other industrial sectors for conveying corrosive or non-polluting media; chemical liquids, waste liquid treatment, acid, industrial liquids and for emergency, standby or filtration purposes; printed circuit boards, semiconductors, electroplating, metal surface finishing, sun treatment, water and wastewater treatment.

For a long time, the selection of acid-and alkali-resistant pump is one of the biggest headaches for chemical practitioners, a little careless, light damage equipment, serious will cause accidents or even disasters. According to relevant statistics, about 60% of the damage of chemical equipment is caused by corrosion, so we should first pay attention to the scientific selection of materials when selecting chemical pumps.

Then we should pay attention to rationality in the usual process of type selection. The so-called reasonable selection of acid and alkali resistant pumps is to comprehensively consider the comprehensive technical and economic indicators such as the investment and operating costs of acid and alkali resistant pump units and acid and alkali resistant pumping stations, so as to make them in line with the principles of economy, safety and application. Specifically, there are the following aspects:

The main contents are as follows:

1. The requirements of flow rate and head must be met, that is, the operation point of the acid-alkali resistant pump (the intersection of the characteristic curve of the device and the performance curve of the acid-alkali resistant pump) is often kept in the high efficiency range, which saves power and is not easy to damage the parts.

2. The selected water acid and alkali resistant pump should not only have small volume, light weight, low cost, but also have good characteristics and high efficiency.

3. It has good anti-cavitation performance, which can not only reduce the excavation depth of the acid-alkali pump room, but also prevent the water acid-alkali pump from cavitation, stable operation and long service life.

4. The acid-alkali-resistant pumping station is built according to the selected acid-alkali pump, which has the advantages of low project investment and low operation cost.
