The corrosion-resistant magnetic pumps of the fc series are driven by high performance magnetic coupling axes, without Any leakage. The liquid-transmission part is made of the invention patent alloy of our companyahigh strength corrosion- Resistant mh series alloy material, stainless or non-metallic material. It has excellent corrosion-resistant performance, a special design and silent running. It is applied in chemical industry, petroleum, metallurgy, spinning industry, chemical fertilizer, medicine industry, print circuit-board, electroplate, aluminum material oxidation coloration and so on. It can transmit various Kinds of alkali, acid, salt, organic acid and organic solution that are between and and without granule (for example, various strength of nitric acid, vitriol, hydrochloric acid, hydrofluoric acid, caustic alkali, chlorate and fluorate). It is especially suitable for the flammable, easy-explosive, volatile, virulent and precious liquid situation.
