The advantages of pneumatic diaphragm pump versus centrifugal pump are introduced.

1. The pneumatic diaphragm pump is driven by air, so the flow is adjusted automatically with the change of the back pressure (export resistance), which is suitable for the medium and high viscosity fluid. The centrifugal pump is a working point of water as a benchmark to set a good, if slightly higher viscosity fluid, requires the supporting reducer or the frequency conversion governor, cost is greatly raised, the gear pump is the same.

2. The pneumatic diaphragm pump can be used for the transport of chemically unstable fluids such as photosensitive materials and flocculation. This is because the shear force of the pneumatic pump is low and the physical impact on the material is small.

3, the site of the bad places, such as construction sites, industrial and mining waste water discharge and the composition is complicated, because of the impurity in the sewage pipe is easy to jam, so to high pumps forming load, motor heating vulnerability. The pneumatic diaphragm pump can be adjusted through the granules and the flow can be adjusted automatically when the pipe is blocked.

4. In the treatment of hazardous and corrosive materials, the material can be completely separated from the outside world, or in some experiments, there is no impurity contamination material.

5. In the flammable and explosive environment, the pneumatic diaphragm pump is reliable and low cost, such as fuel, gunpowder and explosives, because: first, there is no spark after grounding; Second, there is no heat in the work, the machine won't overheat; Third, the fluid does not overheat because the pneumatic diaphragm pump is the least agitated.

6. In addition, the pneumatic diaphragm pump is small and easy to move, no foundation is needed, and the ground is small and easy to install. Can be used as mobile material delivery pump.
