The pneumatic diaphragm pump for mining uses the air flow to push the valve core reciprocating, so that the pressure air alternately enters the left and right air chamber, so that it pushes the diaphragm concave and convex reciprocating motion and produces the pressure difference in the working chamber, to achieve the purpose of water absorption and drainage small size, light weight, no foundation, can be used as a mobile pump, no need for lubrication, the main valve has no special requirements for the air source, and can be self-priming to start running.

The pneumatic diaphragm pump for mining uses the pressure difference in the air chamber to alternately produce the suction liquid pressure and positive liquid pressure in the liquid chamber. After controlling the valve switch to ensure the positive flow of the liquid, the pump starts to run, and continuously works to ensure that the required pressure remains unchanged. The pump will increase and maintain the pressure of the conveying pipe, and when the maximum conveying pipe pressure is reached (or the distributing valve is closed), the pump will increase and maintain the pressure of the conveying pipe. Will stop working and, if needed, resume pumping.
