What type of chemical pump is good to transport 98% sulfuric acid?
The corrosiveness of concentrated sulfuric acid need not be mentioned more. We all know that the higher the temperature, the stronger the corrosiveness. The transportation of concentrated sulfuric acid has always been an important content in industrial production.
There are three options:
1. The use of stainless steel material centrifugal pump, before using, put the flow parts (that is the contact with concentrated sulfuric acid parts) into concentrated nitric acid passivation, so that the surface of the formation of a protective film was formed, thus prolong the service life of the pump! However, this can not solve the problem of pump corrosion undamentally, it will still be corroded with little longer time passed. And the nitric acid passivation process before use is particularly troublesome! Therefore, stainless steel centrifugal pump is should be less used.
2. The use of fluorine lined centrifugal pump, the flow part is fluorine plastic, corrosion resistance is greatly improved, it can withstand any concentration of sulfuric acid, and can be a long time of safe and stable operation. But due to the sealing form of machine seal, the machine seal is easy to leak for a long time.
3. So SAIKEN PUMP recommended fluoroplastics lined magnetic pump without leakage and free maintenance to transfer sulfuric acid, since the density of 98% sulfuric acid is 1.84, all the attention should be paid to increase the motor power with motor, so as to avoid motor burning. Of course you don't have to worry about all this, you just tell us the flow, head, then we choose the correct model type for you.
