Pneumatic diaphragm pump has six advantages, such as reliable quality, long service life, low noise, small vibration, no crash and fine workmanship. It can not only pump flowing liquid, but also transport some media which are not easy to flow. It has many advantages of self-priming pump, submersible pump, shield pump, mud pump and impurity pump.

1. The flow is spacious, and the passing performance is good, allowing the passing of large particles with a diameter of up to 10 mm. When pumping mud and impurities, the pump is slightly worn;

2. The pneumatic one-way diaphragm pump does not need water diversion, the suction head is up to 8.8m, the lift is up to 84m, and the outlet pressure is ≥ 8.4bar;

3. The pneumatic one-way diaphragm pump has no rotating parts and shaft seal. The medium pumped by the diaphragm is completely separated from the moving parts and workpiece medium of the pump, and the medium transported will not leak out. Therefore, when pumping toxic, volatile or corrosive media, it will not cause environmental pollution and endanger personal safety;

4. The head and flow can be adjusted steplessly through the opening of the air valve (the air pressure is adjusted between 1-8.4bar);

5. It can work in submerged medium;

6. No need to use electricity. It is safe and reliable to use in inflammable and explosive places;

7. The pneumatic diaphragm pump has simple structure, few vulnerable parts, simple structure, convenient installation and maintenance. The medium transported by the pump will not contact the moving parts such as valve and connecting rod. Unlike other types of pumps, the performance will gradually decline due to the wear of rotor, piston, gear, blade and other parts;

8. It is convenient to use, reliable to work, and it only needs to open and close the gas valve to start and stop the pump. Even if the pump runs without medium for a long time or stops suddenly due to unexpected circumstances, it will not be damaged. Once the pump is overloaded, it will stop automatically and has self-protection performance. When the load returns to normal, it can start to run automatically;

9. Pneumatic diaphragm pump does not need oil lubrication, even if idling, it has no effect on the pump, which is a major feature of the pump;

10. It can transport viscous liquid (viscosity below 25000 centipoise).
