Advantages of air operated diaphragm pumps

Diaphragm pump is a new type of conveying machinery, which can convey various corrosive liquids, liquids with particles, high-viscosity, volatile, flammable and highly toxic liquids. Diaphragm pumps are available in four materials: plastic, aluminum alloy, cast iron, and stainless steel.
Diaphragm pumps use NBR, neoprene, fluororubber, PTFE, and PTFE according to different liquid media. to meet the needs of different users. It has been installed in various special occasions and used to pump media that cannot be pumped by conventional pumps, and has achieved satisfactory results.
Diaphragm pumps have an absolute dominant position in the paint and ceramic industries. The advantages of pneumatic diaphragm pumps are:
1. Because air is used as power, the flow is automatically adjusted with the change of back pressure (outlet resistance), which is suitable for medium and high viscosity fluids. The working point of the centrifugal pump is set on the basis of water. If it is used for a fluid with a slightly higher viscosity, it needs to be equipped with a reducer or a variable frequency governor, which will greatly increase the cost, and the same is true for the gear pump.
2. Pneumatic pumps are reliable and low-cost in flammable and explosive environments, such as the transportation of fuel, gunpowder, and explosives, because: first, it is impossible to generate sparks after grounding; second, no heat is generated during work, and the machine does not will overheat; third, the fluid will not overheat because the diaphragm pump has minimal agitation of the fluid.
3. In harsh construction sites, such as construction sites, industrial and mining wastewater discharge, due to the large amount of impurities and complex components in the sewage, the pipeline is easy to block, which will cause an excessive load on the electric pump, and the motor will be easily damaged by 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. It can be used to transport fluids with relatively unstable chemical properties, such as photosensitive materials, flocculation liquid, etc. This is because of the low shear force of the diaphragm pump, which has little physical impact on the material.
5. In the treatment of hazardous and corrosive materials, the diaphragm pump can completely separate the materials from the outside world.
6, or in some tests to ensure that no impurities contaminate the raw materials.
In addition, the diaphragm pump is small and easy to move, does not require a foundation, occupies a small area, and is easy and economical to install. Can be used as a mobile material delivery pump.
