Which pump is more suitable for conveying concentrated sulfuric acid? Jan 16, 2023

98% concentrated sulfuric acid, commonly known as bad water, is a commonly used raw material in the chemical industry and is highly corrosive. Many people have asked what pump should be used to transport concentrated sulfuric acid when selecting the type, which has been bothering everyone all the time. Today, Rister will show you which pump is suitable for 98% concentrated sulfuric acid pump.

 

1.Usually, the sulfuric acid with a concentration of 98% is very corrosive, and if it is transported by a traditional metal chemical pump, it will bring serious corrosion to the interior of the pump body. Therefore, it is very appropriate to use Teflon plastic as a lining plastic chemical pump to transport.

 

2.According to the different performance, the plastic chemical pump can be divided into Teflon lined centrifugal pump, Teflon lined magnetic pump, Teflon lined self-priming pump and so on, in which both centrifugal pump and magnetic pump can transport strong corrosion medium of any concentration to solve the transportation problems of sulfuric acid, nitric acid, hydrofluoric acid and other media.

 

3.Teflon lined self-priming pump is used in specific occasions, using the physical characteristics of centrifugal self-priming, it is a pump that can run idling. Teflon lined centrifugal pump and Teflon lined magnetic pump because of their strong corrosion resistance Teflon material as the lining, so corrosion resistance, acid and alkali resistance is stronger than the general plastic material. Therefore, no leakage and leakage can be achieved in the process of conveying highly corrosive media.

 

4.Another key to the transportation of highly corrosive media is the flow rate, which is usually easily overlooked. This is the conclusion drawn by Rister after years of experience. Because the flow rate is too high, the medium temperature has a great influence on the interior of the pump body, especially on the impeller part. usually, the damage of Teflon plastic pump is due to the failure to pay attention to the change of medium temperature in the process of use. thus the damage of temperature to the interior of the pump body is ignored. Therefore, in the process of using a series of plastic pumps, it is also critical to pay attention to the temperature of the medium.
