FB type corrosion-resistant pump is suitable for media without solid particles, with a medium temperature of 0 ℃ to 120 ℃ and an inlet pressure not exceeding 2kg/cm2. The AFB stainless steel corrosion-resistant centrifugal pump is an improved design based on the F-type corrosion-resistant pump, which adopts a new type of impeller power shaft seal device and belongs to a single-stage single suction cantilever corrosion-resistant centrifugal pump. The overcurrent parts of the pump that come into contact with the conveying medium are all made of 1Cr18Ni9Ti material. Used for conveying corrosive liquids without solid particles, with a medium temperature of -20 ℃ to 130 ℃, and a pump inlet pressure not exceeding 2kg/cm2. This pump is widely used in industries such as chemical, petroleum, metallurgy, light industry, synthetic fibers, environmental protection, food, and medicine. This type of product has the advantages of stable and reliable performance, good sealing performance, beautiful appearance, and easy use and maintenance. To improve product quality, reduce running, emitting, dripping, and leaking, and prevent pollution, it plays a significant role.
