Five Advantages Of Products

  • After the pneumatic diaphragm pump is grounded, it is impossible to generate sparks, no heat is generated during work, and the machine will not overheat

  • The fluid of the pneumatic diaphragm pump will not be overheated, because the agitation of the fluid by the pneumatic diaphragm pump is minimal.

  • The pneumatic diaphragm pump can pass particles and the flow rate is adjustable, and it will stop automatically when the pipeline is blocked.

  • The pneumatic diaphragm pump is small in size and easy to move, does not need foundation, occupies a small area, and is easy and economical to install. It can be used as a mobile material delivery pump.

  • In the treatment of hazardous and corrosive materials, the diaphragm pump can completely isolate the material from the outside world. The shear force of the diaphragm pump is low and has little physical impact on the material.

Product Details

Brief introduction of pneumatic diaphragm pump:


Pneumatic diaphragm pump is a new type of conveying machinery. It uses compressed air as the power source. It can pump all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids. . Pneumatic diaphragm pumps are mainly used in spray painting and ceramic industries, and in some other industries, they can also be used in environmental protection, wastewater treatment, construction, sewage discharge, and fine chemicals.


Pneumatic diaphragm pumps are available in four materials: engineering plastics, aluminum alloy, stainless steel, and cast iron. Pneumatic diaphragm pumps use nitrile rubber, neoprene, fluororubber, polytetrafluoroethylene, polytetrafluoroethylene, 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 has achieved satisfactory results.


Advantages of pneumatic diaphragm pump:

1. Due to the use of air as 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 operating point of the centrifugal pump is set based on water. If it is used for a fluid with a slightly higher viscosity, it needs to be equipped with a reducer or a frequency conversion speed controller, and the cost will be greatly increased. The same is true for the gear pump.

2. Pneumatic diaphragm pumps are reliable and low-cost in flammable and explosive environments. Third, the fluid will not overheat because the diaphragm pump has the least agitation of the fluid.

3. In places with bad construction sites, such as construction sites, industrial and mining wastewater discharge, due to the many impurities and complex components in the sewage, the pipelines are easy to be blocked, so the load on the electric pump is too high, and the motor is easily damaged due to heat. The air-operated diaphragm pump can pass particles and the flow rate is adjustable. When the pipeline is blocked, it will automatically stop until it is unobstructed.

4. In addition, the pneumatic diaphragm pump is small in size and easy to move, does not need a foundation, occupies a very small area, and is easy and economical to install. Can be used as a mobile material transfer pump.

5. In the treatment of hazardous and corrosive materials, the diaphragm pump can completely separate the materials from the outside world.

6. Pneumatic diaphragm pumps can be used to transport fluids with relatively unstable chemical properties.

The role of pneumatic diaphragm pumps in the industrial field is huge. Many things that are difficult for humans to do manually can be done by pneumatic diaphragm pumps, which indirectly guarantees the safety of employees.
