What are the applicable occasions for pneumatic diaphragm pumps

Diaphragm pumps can pump both flowing liquids, but also transport some of the media that do not flow easily, and viscous liquids, or liquids containing impurities, with many advantages of self-priming pumps, submersible pumps, shield pumps, mud pumps and impurity pumps and other conveying machinery. It also has a unique self-priming capability, so it is also very widely used in applications.

Mainly used in the food, chemical, sewage, environmental protection and paper industries, the specific needs can be selected according to the working conditions and other experience. Such as: spray paint, ceramic industry diaphragm pump has occupied a dominant position, and in some other work, like environmental protection, waste water treatment, construction, sewage, fine chemical industry is expanding its market share, and has other pumps can not replace the position. Some examples can be given below.

① Suitable for fluids or liquids of medium to high viscosity. Because the working point of the pump is set with water as a benchmark, assuming that it is used for slightly higher viscosity fluids, it requires a matching reducer or frequency converter, the cost is greatly increased, and the same is true for gear pumps. So it is better to use diaphragm pumps at this time.

② in the flammable and explosive environment with pneumatic diaphragm pumps more reliable and safe and low cost, such as the transport of liquids of combustible materials.

Because: first, after grounding the diaphragm pump is unlikely to spark; second, no heat generated in the work, the machine will not produce overheating; third, the fluid will not overheat, because the diaphragm pump on the fluid stirring minimum.

③ in the site of the harsh environment and working conditions, such as construction sites, industrial and mining wastewater discharge, because of the impurities in the sewage and the composition of the more chaotic, easy to block the pipeline, so the electric pump constitutes a high load on the situation, the motor is hot and fragile. The pneumatic diaphragm pump can pass through particles larger and adjustable flow, and the pipeline is automatically suspended to clear when blocked.

④ diaphragm pump is small and easy to move, no foundation, occupying an area of very small, simple and economic installation. Can be used as a mobile material delivery pump.

⑤ in a hazardous, corrosive materials or some tests to ensure that no impurities contaminate the material. In processing, the diaphragm pump can be completely isolated from the outside world by the material being transported alive.

⑥ for the transport of chemically unstable fluids or liquids, such as: photographic materials, flocculants, etc.. This is because the diaphragm pump is relatively stable in its delivery and has little physical impact on the material.
