Acid-proof pump is a kind of chemical pump, which is specially used to transport acid and corrosive substances. As to what kind of acid pump to choose, according to what acid to transport. Below are a list of some of the most common acid-proof pumps.

1. Hydrochloric acid pump

Commonly used the highest concentrations of hydrochloric acid is 38%, so the hydrochloric acid pump as long as it is basically flow components is made of plastic to go, but if from life, price, etc to consider, you can choose the FSB fluorine alloy centrifugal pump or CQB - F magnetic pump, the price of this two kinds of pump, the performance is satisfactory.

2. Sulphuric acid pump

Sulfuric acid pump into the dilute sulphuric acid with sulfuric acid by pump pump, the optional range is larger, dilute sulphuric acid pumps can choose engineering plastic, ceramic, or F46, F26 pump, the latter (sulfuric acid pump) can only choose fluorine plastic (F46) pump, because of sulfuric acid corrosion of common engineering plastics, while fluorine plastic will not corrode. It should also be noted that the density of concentrated sulfuric acid is relatively high. When selecting pump, the power of the motor should be large, and the simple algorithm is “ Shaft power & throughout; *1.84 is the shaft power for conveying concentrated sulfuric acid.

3. Hydrofluoric acid.

The corrosion of hydrofluoric acid is very strong, it is recommended to choose fluorine plastic magnetic pump, (and be sure to replace the ceramic parts of this series of pumps with hydrofluoric acid resistant materials)

4, nitric acid

The nitric acid transport pump also recommends the fluorine plastic magnetic pump, and the rubber sealing ring should be replaced by the four-fluorine material.

5, acetic acid,

It is one of the strongest material corrosion in organic acids, ordinary steel in all concentration and temperature of severe corrosion of acetic acid, acetic acid proof material is stainless steel, 316 stainless steel containing molybdenum can also apply to high temperature and dilute acetic acid steam. High alloy stainless steel or fluorine plastic magnetic pump can be used for high temperature high concentration acetic acid or other corrosive medium. Such as CQB magnetic pump, CQ316L stainless steel magnetic pump.
