AODD diaphragm pump is a new type of conveying machinery, is currently a novel domestic pump class.
Using compressed air as power source, for a variety of corrosive liquids, liquids with particles, high viscosity, volatile, flammable, highly toxic liquids, can be pumped out.

Let’s take a look at the conditions of the AODD diaphragm pump:

Because of the above characteristics, the AODD diaphragm pump in the world since the birth of the diaphragm pump has gradually invaded the other pump market, and occupy a part of them.

For example: paint, ceramic industry diaphragm pump has occupied the dominant position of *, and in some other industries, such as environmental protection, waste water treatment, construction, sewage, fine chemical industry is expanding its market share, and has an irreplaceable position of other pumps.
The advantages of pneumatic diaphragm pump are as follows:

  1. Since air is used as power, the flow rate is automatically adjusted with the change of back pressure (outlet resistance), suitable for medium and high viscosity fluids.
    And the centrifugal pump working point is set with water as a benchmark, if used for viscosity slightly higher fluid, then need to support reducer or variable frequency governor, the cost is greatly increased, for gear pump is the same.
  2. Pneumatic pump is reliable and low cost in inflammable and explosive environment, such as transmission of fire, because: first, it is impossible to generate sparks after grounding;
    Second, there is no heat generated in the work, the machine will not overheat;
    Third, the fluid will not overheat because the diaphragm pump on the fluid agitation * small.

3, in the site of bad places, such as construction sites, industrial and mining waste water discharge, because of the impurities in the sewage and complex composition, pipeline is easy to plug, so on the electric pump will form a high load, motor heating vulnerable.
Pneumatic diaphragm pump through the particles and flow can be adjusted, when the pipeline blocked to stop automatically unobblocked

4, in addition, diaphragm pump small volume easy to move, do not need the foundation, occupy the ground is very small, simple and economical installation.
It can be used as mobile material conveying pump.

5, in the hazardous, corrosive material treatment, diaphragm pump can be completely separated from the material and the outside.

6, or some tests 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, flocculant, etc.
This is because the diaphragm pump shear force is low, the physical impact on the material is small.
