AFB, FB, PWF type corrosion-resistant centrifugal pumps. The overcurrent parts of the pump that come into contact with the conveying medium are made of 1Cr18Ni9Ti material, and the temperature of the conveyed medium ranges from -20 ℃ to 130 ℃. The inlet pressure of the pump generally cannot exceed 0.2Mpa. After special design, it can be used under working conditions with an inlet pressure of 0.35-0.4MPa. It is widely used in industrial sectors such as chemical, petroleum, metallurgy, light industry, synthetic fiber, and medicine. This type of product has stable performance, good sealing, reasonable structure, and easy maintenance, greatly reducing running, emitting, dripping, and leaking, preventing pollution, improving the environment, and playing a great role, which has won high praise from users.
The sealing performance of AFB and FB corrosion-resistant centrifugal pumps is superior, using three different sealing forms: impeller power seal and parking seal device, mechanical seal device, and packing seal device, which are interchangeable.

The PWF type corrosion-resistant sewage pump is an improved single-stage single suction corrosion-resistant centrifugal pump impeller, which can be used to transport liquids containing small amounts of particles, slurry, sewage treatment, etc.
