It uses magnetic rotation, although the price is higher than the centrifugal pump, but there is no leakage, high safety, so the use effect is higher than the centrifugal pump. Now there are stainless steel magnetic pump, fluoroplastic magnetic pump and fluoroplastic magnetic pump on the market, so its corrosion resistance is superior to stainless steel magnetic pump, and it can transport any concentration of acid and alkali. More widely used.
