Pneumatic diaphragm pump material: cast iron, stainless steel, engineering plastics, aluminum alloy, fluorine lined
Pneumatic diaphragm pump is a new type of conveying machinery, is the most novel type of pump in China. Using compressed air as the power source, all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable, highly toxic liquids can be pumped out.
Pneumatic diaphragm pump has four materials: plastic, aluminum alloy, cast iron, stainless steel. Diaphragm pump according to different liquid media respectively using butadiene rubber, neoprene rubber, fluorine rubber, polytetrafluoroethylene, polytetrafluoroethylene. To meet the needs of different users. Placed in a variety of special occasions, used to pump a kind of conventional pump can not pump the medium, have achieved satisfactory results.
Pneumatic diaphragm pump application:
Because the pneumatic diaphragm pump has the above characteristics, the diaphragm pump in the world is gradually invading the market of other pumps since its birth, and occupies a part of it. For example: painting, ceramics industry diaphragm pump has occupied an absolute dominant position, and in some other industries, such as environmental protection, wastewater treatment, construction, sewage, fine chemical industry is expanding its market share, and has other pumps irreplaceable status. The advantages of pneumatic diaphragm pumps are:
1, because the air is used as the power, the flow rate is automatically adjusted with the change of back pressure (outlet resistance), which is suitable for medium and high viscosity fluids. The working point of the centrifugal pump is set on the basis of water, if it is used for fluids with slightly higher viscosity, you need to support the reducer or variable frequency governor, the cost is greatly increased, and the same is true for the gear pump.
2, in the flammable and explosive environment with pneumatic pump reliable and low cost, such as fuel delivery, because: first, after grounding is impossible to produce sparks; Second, no heat is generated in the work, and the machine will not overheat; Third, the fluid will not overheat because the diaphragm pump has minimal agitation for the fluid.
3, in the harsh place of the site, such as construction sites, industrial and mining waste water discharge, due to the impurities in the sewage and complex composition, the pipeline is easy to block, so that the electric pump will form an excessive load, the motor heating is vulnerable. The pneumatic diaphragm pump can pass through the particle and the flow rate is adjustable, and automatically stops to smooth when the pipeline is blocked.
4. In addition, the diaphragm pump is small and easy to move, does not require foundation, occupies very little ground, and is simple and economical to install. Can be used as mobile material transfer pump.
5, in the hazardous, corrosive material treatment, diaphragm pump can completely separate the material from the outside world.
6, or some tests to ensure that there is no impurity pollution of raw materials.
7, can be used to transport chemical properties of relatively unstable fluid, such as: photosensitive materials, flocculant, etc. This is because the shear force of the diaphragm pump is low and the physical impact on the material is small.
