Pneumatic diaphragm pump since the birth of the rapid invasion of other pump market, and occupy part of it. Pneumatic diaphragm pump is a new type of transport machinery, is currently the most innovative kind of pump. The use of compressed gas as the power source, for a variety of corrosive liquids, with the particles of liquid, high viscosity, volatile, flammable, highly toxic liquid, can be exhausted.
Pneumatic diaphragm pump has four kinds of materials: plastic, aluminum, cast iron, stainless steel. Pneumatic diaphragm pump according to different liquid media were used Dingqing rubber, chloroprene rubber, fluorine rubber, polytetrafluoroethylene, poly tetrahexaethylene, to meet the needs of different users. Placed in a variety of special occasions, used to draw a variety of conventional pumps can not smoke the media, have achieved satisfactory results.
1, due to gas for power, so the flow with the back pressure (outlet resistance) changes and active adjustment, suitable for high viscosity fluid. The working point of the centrifugal pump is set on the basis of water, if the viscosity is slightly higher for the fluid, you must complete the reducer or frequency converter, the cost is greatly improved, for the gear pump is also true.
2, in the flammable and explosive environment with pneumatic pump reliable and low cost, such as fuel, gunpowder, explosives transport, because: first, after the ground can not produce sparks; second, no heat generated in the work, the machine is not Will be overheated; third, the fluid will not overheat because the pneumatic diaphragm pump on the minimum agitation of the fluid.
3, in the construction of the poor center, such as the construction site, industrial and mining wastewater discharge, due to the impurities in the sewage and more complex components, the pipeline is easy to infarction, so that the formation of high pressure on the electric pump environment, the motor heat vulnerable. Pneumatic diaphragm pump can be through the particles and flow adjustable, pipeline obstruction active stop.
4, the other pneumatic diaphragm pump small size easy to move, do not need the foundation, small footprint, easy to install economy. Can be used as a moving material pump.
5, in a hazardous, corrosive material handling, the diaphragm pump can be completely isolated from the outside world.
6, or some experiments to ensure that no impurities contaminated raw materials.
7, can be used to transport more unstable chemical properties of the fluid, such as: photosensitive materials, flocculation and so on. This is because the diaphragm pump shear force is low, the physical impact of the material is small.
