3 allPneumatic diaphragm pump is a new type of conveying machinery, which has a very important position in the process of modern industry, it can not only transport all kinds of corrosive liquids, liquids with particles, but also can transport high-viscosity, volatile, flammable, highly toxic liquids.

**Around a thousand. Pneumatic diaphragm pumps are invading the market of other pumps at a very fast speed, and occupy a very important share in the pump market, especially in the painting and ceramic industries, diaphragm pumps have occupied a dominant position, mainly due to the performance advantages of diaphragm pumps, but some congenital deficiencies, diaphragm pumps are also limited in some fields.

Advantages and disadvantages of air-operated diaphragm pumps

Advantages and features: 1. The diaphragm pump is small in size and easy to move, does not need a foundation, occupies a very small ground, is easy to install and economical, and can be used as a mobile material transfer pump.

2. In flammable and explosive environments, the pneumatic diaphragm pump is reliable and low-cost such as fuel transportation, and it is impossible to produce sparks after grounding.

3. In the harsh places of the construction site, such as the construction site, the wastewater discharge of industrial and mining facilities, due to the many impurities in the sewage and the complex composition, the pipeline is easy to block, so that the electric pump will form a situation of excessive load, and the motor is heating and vulnerable. The air-operated diaphragm pump can pass through particles and the flow rate is adjustable, and it automatically stops to unobstructed when the pipe is blocked.

4. It can be used to transport fluids with relatively unstable chemical properties.

5. In the handling of hazardous and corrosive materials, the diaphragm pump can completely isolate the material from the outside world.

Disadvantages of air-operated diaphragm pumps:

1. The pressure cannot be increased, and it is limited by the pressure of the air source, and the upper limit is reached at 6bar;

2. Noise and pipeline vibration are particularly obvious in atmospheric volume;

3. Compared with the screw pump, the diaphragm has a short life and is easy to be damaged;

4. Because the flow rate of diaphragm pump is usually not too large, most of them are used in small systems.

According to the brand, model, caliber, material and other reasons, the diaphragm pump has a large deviation.

Working principle and characteristics:

Pneumatic diaphragm pump is a kind of volumetric pump powered by compressed air and volume change caused by reciprocating deformation of diaphragm, its working principle is similar to that of piston pump, due to the characteristics of the working principle of pneumatic diaphragm pump, so the air-operated diaphragm pump has the following characteristics:

1) The pump will not overheat: the compressed air is the driving force, which is an expansion and heat-absorbing process when exhausting, and the temperature is reduced when the pneumatic pump is working, and no harmful gas is discharged.

2) No electric sparks: The pneumatic diaphragm pump does not use electricity as power, and it prevents electrostatic sparks after grounding.

Applicable occasions:

Because of the above characteristics of air-operated diaphragm pumps, air-operated diaphragm pumps have gradually invaded the market of other pumps since their birth and occupied a part of them.

For example, the pneumatic diaphragm pump in the painting and ceramic industry has occupied an absolute dominant position, while in some other industries, such as environmental protection, wastewater treatment, construction, sewage discharge, and fine chemicals, it is expanding its market share, and has an irreplaceable position for other pumps.

The above content reference: Encyclopedia - pneumatic diaphragm pump.

Generally speaking. Diaphragm pumps are based on the brand, model, caliber, material and other reasons, and the production process of different manufacturers is different. Its ** deviation is relatively large.

There are really few domestic manufacturers specializing in the production of diaphragm pumps, looking at the company's qualifications and patents, standardized companies pay more attention to the maintenance of intellectual property rights, and if conditions permit, they can be inspected on the spot.

It is right to choose Shanghai Sunshine Manufacturing, which is currently a well-known brand and famous trademark in the domestic pump industry, and it is excellent in all aspects.

Summary. Dear, hello, the expansion is as follows: pneumatic diaphragm pump is a new type of conveying machinery, using compressed air as the power source, for all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable, highly toxic liquids, can be pumped and absorbed.

The air-operated diaphragm pump is available in four materials: engineering plastic, aluminum alloy, stainless steel, and cast iron. The air-operated diaphragm pump adopts nitrile rubber, neoprene, fluorine rubber, PTFE, polytetrahexaeethylene, etc. according to different liquid media to meet the needs of different users.

It is placed in various special occasions and used to pump various media that cannot be pumped by conventional pumps, and satisfactory results have been achieved.

Hello dear, very happy to answer your questions<>

The top 10 are Wilton, ARO, Yamada, Sandpiper, Versamatic, Graco, Debem, Blagdon, Verder, and TapFlo.

It is placed in various special occasions and used to pump various media that cannot be pumped by conventional pumps, and satisfactory results have been achieved.

Summary. Dear, hello, the expansion is as follows: pneumatic diaphragm pump selection method:

1. First of all, it is necessary to confirm whether it is suitable for using an air-operated diaphragm pump. The head of the pneumatic diaphragm pump is about 50 meters and the diameter is about 100 mm. If you need a head or bore much larger than his parameters, then an air-operated diaphragm pump is not suitable.

2. Selection of flow rate and caliber. Because the head of the air-operated diaphragm pump is fixed, even if some manufacturers claim that their air-operated diaphragm pump can reach 70 meters, but that is only their deliberate exaggeration, if the pressure is too large, then the pump shouming will be seriously affected! Therefore, according to the flow rate and caliber you need, you can choose the right air-operated diaphragm pump.

3. According to the corrosiveness, temperature, concentration and viscosity of the liquid, select pneumatic diaphragm pumps of different materials. The materials of the pneumatic diaphragm pump are cast iron, aluminum alloy, stainless steel, engineering plastics, rubber lining, fluorine lining, etc., and the materials of diaphragm, sealing ball and ball seat are nitrile rubber, tetrafluorine, F46, fluoroelastomer, etc., and different materials are selected according to different liquids.
