6 practical advantages of pneumatic diaphragm pumps:

 1. Since air is used as power, the flow rate is automatically adjusted with changes in back pressure (outlet resistance), and is suitable for medium and high viscosity fluids. The working point of the centrifugal pump is set based on water. If it is used for fluids with a slightly higher viscosity, it will need to be equipped with a reducer or frequency converter, which will greatly increase the cost. The same is true for gear pumps.

2. Pneumatic diaphragm pumps are reliable and low-cost in flammable and explosive environments, such as the transportation of fuel, gunpowder, and explosives, because: first, sparks are not possible after grounding; second, no heat is generated during operation , the machine will not overheat; third, the fluid will not overheat because the diaphragm pump causes minimal agitation of the fluid.

3. In harsh construction sites, such as construction sites, industrial and mining wastewater discharges, due to the large number of impurities and complex composition in the sewage, the pipes are prone to blockage, which causes an overload on the electric pump, and the motor is easily damaged due to heat. The pneumatic diaphragm pump can pass particles and the flow rate is adjustable. When the pipeline is blocked, it will automatically stop until it becomes unobstructed.

4. In addition, the pneumatic diaphragm pump is small and easy to move, does not require 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 processing of hazardous and corrosive materials, pneumatic diaphragm pumps can completely isolate the materials from the outside world.

6. Pneumatic diaphragm pumps can be used to transport fluids with relatively unstable chemical properties, such as photosensitive materials, flocculation liquids, etc. This is because diaphragm pumps have low shear forces and have little physical impact on materials.
