1. Due to the use of air as the power, the flow is automatically adjusted 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 set based on water. If it is used for a fluid with a slightly higher viscosity, a reducer or frequency converter is required. The cost is greatly increased. The same is true for a gear pump.
2. It is reliable and low cost to use pneumatic pump in flammable and explosive environment. Such as fuel, explosives, because: First, after the earth can not produce sparks; Second, there is no heat generated during the work, the machine will not overheat; Third, the fluid will not overheat because the diaphragm pump agitation of the fluid is minimal.
3. In the bad places of the construction site, such as the construction site, waste water discharge from the industrial and mining, and the impurities in the sewage are complicated and the components are complex, the pipeline is easy to be clogged. This causes the load on the electric pump to be too high and the motor heat to be vulnerable. Pneumatic diaphragm pump can pass through the particles and the flow can be adjusted. When the pipe is blocked, it stops automatically until it is smooth.
4. In addition, the diaphragm pump is small in size and easy to move, requires no foundation, occupies minimal ground, and is simple and economical to install. Can be used as a mobile material pump.
5. In the treatment of hazardous and corrosive materials, the diaphragm pump can completely separate the material from the outside.
6, or some tests to ensure that no impurities contaminate the raw materials.
7, can be used to transport fluids with relatively unstable chemical properties, such as: photosensitive materials, flocculants and so on. This is because the diaphragm pump has a low shear force and a small physical impact on the material.
Pneumatic diaphragm pumps have the above characteristics, so in the world since the birth of the diaphragm pump is gradually invading the market of other pumps, and occupies part of it. Such as: spray paint, ceramic diaphragm pump has occupied an absolute dominant position, and in other industries, such as environmental protection, wastewater treatment, construction, sewage, fine chemicals is expanding its market share, and has other pumps can not be replaced The status.
