Today, on Saturday, I was on duty in the factory and a user called and asked us how to choose the type of hydrochloric acid pump? Anything to pay attention to, he told me that the hydrochloric acid pump used before was often damaged, and the machine seal was changed at both ends for three days, and the impeller was changed. Then the question comes, what did the other party choose?
Today, on Saturday, I was on duty in the factory and a user called and asked us how to choose the type of hydrochloric acid pump ? Anything to pay attention to, he told me that the hydrochloric acid pump used before was often damaged, and the machine seal was changed at both ends for three days, and the impeller was changed.
So the question is, what pump did the other party choose? Will it cause two days of bad?
Many chemical users need to use a hydrochloric acid pump, so how should the hydrochloric acid pump be selected, which pump is better, and what are the precautions?
Let me briefly introduce the key points for selecting the hydrochloric acid pump:
First of all, it is important not to choose stainless steel 304 or 316L for hydrochloric acid pumps. Generally, non-metal pumps are used, such as plastic pumps.
If the pure hydrochloric acid is delivered, then I recommend using a fluorine lined magnetic pump . It should be noted that hydrochloric acid is not corrosive to most plastics, and it is corrosive to most metals.
Here are some introductions of hydrochloric acid, taken from Baidu Encyclopedia:
Hydrochloric acid [1] is an aqueous solution of hydrogen chloride (HCl) [2], which belongs to a monobasic inorganic strong acid and has a wide range of industrial applications. Hydrochloric acid is a colorless and transparent liquid with a strong pungent odor and high corrosiveness. Concentrated hydrochloric acid (mass fraction is about 37%) is extremely volatile, so when the container containing concentrated hydrochloric acid is opened, the hydrogen chloride gas will volatilize and combine with water vapor in the air to generate small droplets of hydrochloric acid, making the acid appear above the bottle mouth. fog. Hydrochloric acid is the main component of gastric acid, which can promote food digestion and protect against microbial infections.
Seeing here, everyone should know what precautions for hydrochloric acid pump.
