-Magnetic pump for 30°C fluoride and chloride-containing media
Thread Content
1. Medium temperature is around -30 degrees Celsius; it is corrosive, and the local altitude is 2600 meters. Are there any recommended magnetic pumps for low-temperature corrosion prevention? 2. There is another requirement: the medium needs to be made of carbon steel and the operating temperature should be 200 degrees. Are there any manufacturers that can recommend such products?
1. -30℃ is not a problem; the only thing to consider is whether the material will crystallize at this temperature. Fluoroplastics are resistant to the corrosive effects of chloride ions, but the issue lies in the permeability of fluoride ions. This problem can also be solved by using magnetic pumps with a special design. 2. For carbon steel, as long as it can resist corrosion by the material at 200 degrees, there is no problem. The main considerations are the thermal expansion rate of the pump shaft, the choice of magnetic materials, and whether cavitation occurs with the material; if these three factors are taken into account, then there should be no issues.

-Won’t the fluoroplastic pump casing become very brittle and crack at 30°C? Carbon steel pumps are centrifugal pumps. For these two pumps, it’s difficult to choose from the ones we make ourselves; so let’s see if there are any recommendations
We are in the same industry; the fluoroplastic magnetic pumps produced by our factory are used outdoors in the Northeast for unloading purposes. They can handle temperatures as low as -35 degrees Celsius in winter without any problem, so you might want to give them a try.
It’s not the ambient temperature; it’s the medium temperature
