How are magnetically driven submersible pumps for liquid chlorine?

Currently, there is a company in Dalian that produces magnetically driven submersible pumps for liquid chlorine; these are also leak-free pumps. There is no chlorine consumption and no nitrogen consumption. But I wonder if this type of pump is reliable in operation? # ， ， &
I’ve heard of this type of pump; it is said to have a double shielding layer, and once the inner shielding layer is damaged, the pressure gauge will indicate it, making it easy to carry out repairs promptly. A chlor-alkali plant nearby uses this type of pump, and I haven’t heard them say that this kind of pump can be used for other purposes as well.

I hope you will learn more about its usage so that it can facilitate communication and learning among everyone.

I’m not sure how widely it’s used, but it’s likely to be much more expensive than ordinary liquid chlorine pumps. Nowadays, handling liquid chlorine is considered a hazardous process; without sufficient track record, it’s difficult to get such projects approved. Many people prefer to choose products that may not be the most technologically advanced but do have a proven track record, just for safety and reliability reasons. Anyway, I believe we should keep up with the times:D
For the transportation or filling of liquid chlorine, submersible pumps are commonly used in China. In recent years, shielded pumps and magnetic pumps have also become available; these two types are similar in that they use a shielding or isolation sleeve to separate the liquid chlorine from the driving mechanism. In my opinion, the safety level of these pumps is not as high as that of submersible pumps, but their advantage lies in the ease of maintenance. Our company has both submersible pumps and magnetic pumps. The use of shielded pumps and magnetic pumps requires higher standards regarding the cleanliness of the liquid chlorine. If the liquid chlorine meets those requirements, submersible pumps can generally be used for several years without the need for maintenance. Therefore, I believe that in cases where equipment management is not thorough enough, or for new facilities, submersible pumps are the better choice.

For ordinary liquid chlorine pumps, the most important issue is to ensure that the pump does not suffer from cavitation; it isn’t that crucial whether a shielded pump or a magnetic drive pump is used. Overall, liquid chlorine pumps are quite challenging to manufacture; there are few companies in China that are capable of producing such pumps successfully. If any, please recommend them.
