The CWS marine double suction mid-open horizontal centrifugal pump is a single-stage, double-suction, horizontally split-case centrifugal pump. It's used to transfer fresh water and liquids with similar physical and chemical properties. When the overflow components are made of stainless steel or coated with SEBF high-performance epoxy powder coating, it can handle corrosive liquids. The maximum temperature of the conveyed liquids should not exceed 80℃. It's applicable for water supply and drainage in factories, mines, cities, power stations, and agricultural flood control and irrigation projects. It's commonly used in capital ships and float boatyards.
