1.The all-plastic pneumatic diaphragm pump can not only pump flowing liquids, but also transport some difficult-to-flow media. It has many advantages of self-priming pumps, submersible pumps, canned motor pumps, mud pumps and impurity pumps..
2. No need to irrigate and divert water, the suction range is as high as 10m, the head is 70m, and the outlet pressure is ≥6kgf/cm2.
3. The flow is spacious, the passing performance is good, and the maximum particle diameter allowed is 4mm. When pumping mud and impurities, there is little wear on the pump.
4. The head and flow can be adjusted steplessly through the valve opening (air pressure adjustment is between 1-7kgf/cm2).
5.The pump has no rotating parts and no shaft seal. The diaphragm completely separates the pumped medium from the moving parts of the pump and the workpiece medium, and the conveyed medium will not leak out. Therefore, when pumping easy to play or corrosive media, it will not cause environmental pollution and endanger personal safety.

[SAFETY and EXPLOSION-PROOF] The operating pressure is between 1~8.3 bar, driven by air pressure. A Pneumatic Double Membrane Pump can dry-run for extended periods of time without getting overheated. Blocked suction or discharge pipework, the pump will stop due to air pressure balance, and the pipeline pressure will not continue to rise, not causing the danger of pipeline rupture and liquid leakage..
[AODD PUMP CAN HANDLE A WIDE RANGE OF PH LEVELS] The pneumatic diaphragm pump design isolates the conveyed fluid from the pumping chamber. Diaphragm Pump is ideal for pumping highly corrosive and hazardous chemical fluids and volatile. Normal operation will not cause harm to the environment and operators..
[Wide Applications] The diaphragm pump is suitable for almost of fluids. Pumps can be widely used in the automation industry, water treatment, mining, petroleum, oil and gas, coating, printing, electroplating, chemical industry, electronics, construction, Pharmaceutical, metallurgy, and other industries..
