The diaphragm pump adopts NBR, neoprene, fluororubber, polytetrafluoroethylene and polytetraethylene according to different liquid media. To meet the needs of different users. It is placed in various special occasions to pump media that cannot be pumped by conventional pumps, and has achieved satisfactory results.

Diaphragm pumps have occupied an absolute leading position in the paint and ceramic industries. The advantages of pneumatic diaphragm pumps are:

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

2. The pneumatic pump is reliable and low cost in flammable and explosive environments, such as the transportation of fuel, gunpowder and explosives, because: first, it is impossible to generate sparks after grounding; Second, there is no heat generated during operation, and the machine will not overheat; Third, the fluid will not overheat because the diaphragm pump has the smallest agitation to the fluid.

3. In the harsh places of the construction site, such as the construction site, industrial and mining wastewater discharge, the pipeline is easy to be blocked due to the large number of impurities and complex composition in the sewage, so the electric pump will be overloaded, and the motor will be vulnerable to heat. The pneumatic diaphragm pump can pass the particles and the flow is adjustable. When the pipe is blocked, it will automatically stop to be smooth.

4. It can be used to transport fluid with unstable chemical properties, such as photosensitive materials, flocculating liquid, etc. This is because the diaphragm pump has low shear force and little physical impact on materials.

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

6. Or some tests ensure that there is no impurity polluting the raw materials.

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