This series of pumps is a single-stage, single-suction, cantilever centrifugal pump, which is an energy-saving product determined by the Ministry of Machinery to replace the F-type centrifugal pump. It is suitable for transferring corrosive liquids with a viscosity similar to water in chemical processes. The pump can be widely used in chemical industry, petroleum, metallurgy, electric power, paper making, food, pharmaceutical, synthetic fiber and other industries. The temperature of the medium is generally -20~15℃. If appropriate cooling measures are adopted, the medium with a higher temperature can be transferred.
