The HYF series chemical submersible pump is a vertical single-stage single suction centrifugal pump. Used for transporting corrosive liquids that do not contain solid particles and are not easily crystallized (specially customized to transport trace amounts of crystalline liquids). The temperature of the conveyed medium is -20 ℃ -200 ℃. The working part of the submersible pump is submerged in the liquid, and there is no leakage in the shaft seal. And it has the characteristics of small footprint, reliable use, easy maintenance, and strong corrosion resistance. Widely applicable to industrial sectors such as chemical, pharmaceutical, papermaking, and petroleum industries.
