  Air operated double diaphragm pump is a positive displacement pump, which skillfully utilizes compressed air as a power source, and realizes fluid transfer by alternately driving the movement of two diaphragms, pushing and pulling like two diligent workers, sucking the fluid in from the inlet, and then discharging it from the outlet.

The working principle of an air diaphragm pump is simple yet effective. It uses compressed air to power two diaphragms that move back and forth. This reciprocating motion creates a vacuum and differential pressure, allowing the pump to draw fluid in through the inlet and push it out through the outlet. This process is continuous, allowing the fluid to flow smoothly and unobstructed. The Rongpeng R8411 air double diaphragm pump is one of the products that stand out from the rest.

This double diaphragm pump has an excellent design. It can output a maximum pressure of 7 bar, which is not a small pressure, and can easily deal with a variety of high-pressure transportation tasks. Moreover, its maximum flow rate can reach 450 liters per hour (at 5 bar pressure), which means that it can transport a large amount of fluid per unit of time, making it extremely efficient.

The following are scenes where the R8411 air double diaphragm pump can actually be used, allowing you to more intuitively understand what a practical product this is.
Chemical Industry
Made of carefully selected corrosion-resistant materials, with an aluminum alloy body and NBR diaphragm, the R8411 conveys corrosive chemicals such as acids and alkalis used in the chemical industry, and has a sturdy construction that will not leak. It ensures safe and reliable transportation of hazardous substances.

Wastewater Treatment
In wastewater treatment plants, the R8411 ball valve offers excellent resistance to particles. Because the R8411 is able to draw fluid from below the pump inlet, it can effectively handle sludge and other contaminated fluids.
Mining
Mining operations often require the transfer of highly abrasive slurries and slurries, and the R8411's abrasion-resistant components and powerful pumping capacity of 7 bar make it suitable for such conditions and able to withstand the environment of continuous operation at mining sites.
Automotive Manufacturing
In the automotive manufacturing industry, the RONGPENG R8411 double diaphragm pump is able to convey high viscosity paints and still maintain a stable pressure and flow rate to ensure uniformity and quality. And it can guarantee long time operation.
Construction
The portability and power of the R8411 comes in handy during construction work, where the high pressure of 7 bar and the precisely controlled output of the ball valve can both pump concrete and clean up spills.
Metal and Equipment Fabrication
For metal fabrication and equipment manufacturing, the R8411 is made of an aluminum alloy that can withstand high-pressure work environments. It can handle coolants, lubricants and cleaning agents, providing the hydraulic power necessary for machining and other processes.

If you need an air operated double diaphragm pump for your work, then choose it, such a high quality R8411 air diaphragm can definitely help you.
