Pneumatic diaphragm pump is a new type of conveying machinery and is currently the most innovative pump type in China. Using compressed air as the power source, for various corrosive liquids.
Pneumatic diaphragm pumps have four types of materials: engineering plastics, aluminum alloy, cast iron, and stainless steel. Pneumatic diaphragm pumps use nitrile rubber, chloroprene rubber, fluororubber, polytetrafluoroethylene, and polytetrafluoroethylene according to different liquid media. To meet the needs of different users. Placed in various special occasions, it has achieved satisfactory results in pumping media that cannot be pumped by conventional pumps.
The advantages of pneumatic diaphragm pumps are:
1. Due to the use of air as power, the flow rate automatically adjusts with changes in back pressure (outlet resistance), making it suitable for medium to high viscosity fluids. The working point of a centrifugal pump is set based on water. If it is used for fluids with slightly higher viscosity, a reducer or frequency converter is required, which greatly increases the cost. The same applies to gear pumps.
2. Using pneumatic pumps in flammable and explosive environments is reliable and cost-effective. For example, the transportation of fuel, gunpowder, and explosives, because: firstly, sparks cannot be generated after grounding; Secondly, there is no heat generated during work, and the machine will not overheat; Thirdly, the fluid will not overheat because the diaphragm pump causes minimal agitation to the fluid.
3. In harsh areas of construction sites, such as construction sites and industrial and mining wastewater discharge, due to the high amount of impurities and complex composition in the wastewater, the pipeline is prone to blockage, resulting in excessive load on the electric pump and easy damage to the motor due to heating. The pneumatic diaphragm pump can pass through particles and has an adjustable flow rate. When the pipeline is blocked, it automatically stops until it is unobstructed.
4. In addition, the diaphragm pump has a small volume and is easy to move, does not require foundation, occupies a very small area, and is easy to install and economical. Can be used as a mobile material conveying pump.
5. In the treatment of hazardous and corrosive materials, diaphragm pumps can completely isolate the materials from the outside world.
6. Or some experiments can ensure that there are no impurities contaminating the raw materials.
7. Can be used to transport fluids with relatively unstable chemical properties, such as photosensitive materials, flocculants, etc. This is because the shear force of the diaphragm pump is low, which has little physical impact on the material.
