Basic overview of pneumatic diaphragm pumps

Pneumatic diaphragm pump is a new type of conveying machinery, using compressed air as the power source, for a variety of corrosive liquids, liquids with particles, high viscosity, volatile, flammable, highly toxic liquids, can be pumped and sucked out.

Pneumatic diaphragm pump is a new type of conveying machinery, is the most innovative domestic a pump. The use of compressed air as a power source, for a variety of corrosive liquids can be used.

The pneumatic diaphragm pump has four materials: engineering plastic, aluminum, stainless steel, cast iron. Pneumatic diaphragm pump according to the different liquid media were used nitrile rubber, neoprene, fluorine rubber, polytetrafluoroethylene, polytetramethylene, etc., to meet the needs of different users. Placed in a variety of special occasions, used to pump a variety of conventional pumps can not pump the media, have achieved satisfactory results.

Because the pneumatic diaphragm pump has the above characteristics, so the pneumatic diaphragm pump since its birth is gradually invading the market of other pumps, and occupy a part of it. Such as: spray painting, ceramics industry in the pneumatic diaphragm pump has taken the absolute dominant position, and in some other industries, such as environmental protection, waste water treatment, construction, sewage, fine chemical industry is expanding its market share, and has the irreplaceable position of other pumps.

Pneumatic diaphragm pump is a new type of conveying machinery, is the most novel kind of pump in China. Using compressed gas as the power source, for a variety of corrosive liquids, liquids with particles, high viscosity, volatile, flammable, highly toxic liquids, can be pumped out and sucked up. Pneumatic diaphragm pumps are available in four materials: plastic, aluminium, cast iron and stainless steel. Pneumatic diaphragm pump according to the different liquid media were used nitrile rubber, neoprene, fluorine rubber, polytetrafluoroethylene, polytetramethylene. To meet the needs of different users. Placed in a variety of special occasions, used to pump a variety of conventional pumps can not pump the media, have achieved satisfactory results.

1, because of the use of gas for power, so the flow rate with the back pressure (outlet resistance) changes and active adjustment, suitable for medium and high viscosity fluid. The working point of the centrifugal pump is set by water, if it is used for a slightly higher viscosity fluid, it is necessary to match the reducer or frequency converter, the cost is greatly increased, for gear pumps as well.

2, in the flammable and explosive environment with pneumatic pumps reliable and low cost, such as fuel, gunpowder, explosives delivery, because

Firstly, no sparks are likely to be generated after grounding.

second, no heat is generated during operation and the machine does not overheat

Thirdly, the fluid will not overheat because the pneumatic diaphragm pump has minimal stirring of the fluid.

3, in the site of the poor central, such as construction sites, industrial and mining wastewater discharge, due to the impurities in the sewage and the composition of the complex, the pipeline is easy to infarction, so that the electric pump will form a high load environment, the motor heat vulnerable. Pneumatic diaphragm pump can pass particles and adjustable flow, the pipeline is blocked when the initiative to stop.

4, in addition, pneumatic diaphragm pumps are small in size and easy to move, do not need a foundation, covers an area of small, simple and economic placement. Can be used as a mobile material transfer pump.

5, in a hazardous, corrosive material handling, diaphragm pumps can be completely isolated from the outside world.

6, or some experiments to ensure that no impurities contaminate the raw materials.

7, can be used to transport chemically unstable fluids, such as: photographic materials, flocculation fluid, etc.. This is because of the low shear force of the diaphragm pump, the physical impact on the material is small.
