Pneumatic diaphragm pump is a new type of conveying machinery and it is the most novel type of pump in China at present (this sentence was applied around 2001). Compressed gas is used as the power source. For all kinds of corrosive liquids, liquids with particles, liquids with high viscosity, volatile, flammable, and highly toxic can all be pumped out. The pneumatic diaphragm pump has four materials: plastic, aluminum alloy, cast iron, and stainless steel. Pneumatic diaphragm pump according to different liquid media distinguish using NBR, chloroprene rubber, fluorine rubber, PTFE, polytetraethylene. To meet the needs of different users. Placed in a variety of special occasions, used to pump a variety of conventional pump can not pump the media, have achieved satisfactory results.

1. Because it is powered by air, the flow is actively regulated with the change of back pressure (outlet resistance) and is suitable for medium and high viscosity fluids. The operating point of the centrifugal pump is therefore set as a good reference. If it is used for a fluid with a slightly higher viscosity, it must be matched with a speed reducer or a frequency converter, and the cost is greatly improved. This is also true for a gear pump.

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

3. Pneumatic diaphragm pumps can be used in applications where the media is not expected to be contaminated.

4. Pneumatic diaphragm pumps can be used to transport fluids that are chemically unstable, such as photosensitive materials, flocculation fluids, etc. This is because the diaphragm pump has a low shear force and a small physical impact on the material.

5 in the flammable and explosive environment with pneumatic pumps reliable and low cost, such as fuel, gunpowder and other media delivery, because: First, after grounding can not produce sparks; second, no heat in the work, the machine does not It will overheat; Third, the fluid will not be overheated because of the minimal agitation of the fluid by the pneumatic diaphragm pump.

6. In the harsh center of the construction site, such as construction site, industrial and mining waste water discharge, due to many impurities in the sewage and large components, the pipeline is easy to inflict, so that the electric pump will form an overloaded environment, the motor heat is vulnerable. Pneumatic diaphragm pumps can pass through the particles and the flow rate can be adjusted. When the pipe is blocked, it can be stopped to delay.

7. Other pneumatic diaphragm pumps are small and easy to move, unnecessary foundations, occupy minimal floor space, and are simple and economical to install. It can be used as a moving material pump.
