1. Since air is used as power, the flow rate is automatically adjusted with the change of back pressure (outlet resistance), which is suitable for medium and high viscosity fluids. The working point of centrifugal pump is set based on water. If it is used for the fluid with higher viscosity, it needs to be equipped with reducer or frequency converter, so the cost is greatly increased, and the same is true for gear pump.

2. Pneumatic diaphragm pump in flammable and explosive environment with pneumatic pump reliable and low cost, third, the fluid will not overheat, because the diaphragm pump on the fluid agitation is small.

3. In bad places, such as construction sites, industrial and mining wastewater discharge, due to the impurities in the sewage and complex composition, the pipeline is easy to block, so the electric pump will form the situation of high load, and the motor will heat easily. The pneumatic diaphragm pump can pass through particles and the flow rate is adjustable. When the pipeline is blocked, it will automatically stop until it is unobstructed.

4. In addition, the pneumatic diaphragm pump is small, easy to move, does not need foundation, covers a small area, and is easy to install and economical. It can be used as a mobile material delivery pump.

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

6. Pneumatic diaphragm pump can be used to transport fluid with unstable chemical properties.

The role of pneumatic diaphragm pump in the industrial field is huge, many difficult to be completed by human hand can be completed by pneumatic diaphragm pump, indirectly ensuring the safety of employees.
