1. Since air is used as power, the flow is automatically adjusted with the change of back pressure, which 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 a fluid with a slightly higher viscosity, a reducer or frequency converter is required, and the cost is greatly increased. The same is true for gear pumps.
2. It is reliable and low-cost to use pneumatic pumps 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 generation during work, and the machine does not It will overheat; third, the fluid will not overheat because the diaphragm pump has the least agitation to the fluid.
3. In addition, the diaphragm pump is small in size and easy to move, does not require foundation, occupies a very small area, and is easy and economical to install. Can be used as a mobile material transfer pump.
4. In places with harsh construction sites, such as wastewater discharge from construction sites and industrial mines, due to the large amount of impurities and complex components in the sewage, the pipeline is easy to block, so that the electric pump will be overloaded and the motor will be easily damaged due to heat. The pneumatic diaphragm pump can pass particles and has an adjustable flow rate. When the pipeline is blocked, it will automatically stop until it is unobstructed.
5. Or ensure that no impurities contaminate raw materials in some tests.
6. It can be used to transport fluids with relatively unstable chemical properties, such as photosensitive materials, flocculation fluids, etc. This is because the shear force of the diaphragm pump is low and the physical impact on the material is small.
7. In the treatment of hazardous and corrosive materials, the diaphragm pump can completely isolate the materials from the outside world. Diaphragm pump manufacturers and suppliers from China
