1. Due to the use of air for power, the flow is adjusted automatically with the change of back pressure (exit resistance), which is suitable for medium and high viscosity fluids. And 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, costs are greatly increased 1, by using air as the power, so the traffic along with the change of back pressure (outlet resistance) automatically adjust, suitable for 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 pump is reliable and low cost in the flammable and explosive environment, such as fuel, gunpowder and explosives, because: first, there is no spark after grounding; Second, there is no heat in the work, the machine will not overheat; Third, the fluid does not overheat because the diaphragm pump is the least agitated. Sanitary pump

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 adjustable through the particle and the flow can be adjusted automatically when the pipe is blocked.

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

5. In the treatment of hazardous and corrosive materials, the diaphragm pump can completely separate the material from the outside.

6. In some experiments, there is no impurity contamination material.

7. It can be used for the transport of unstable fluids such as photosensitive materials and flocculation. This is because the diaphragm pump has a low shear force and has little physical impact on the material.
