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.
