The BQG serial of coal mine pneumatic diaphragm pump is small in size, low power consuming,no bearing,lubricant free and corrosion resistant. The whole machine is well sealed and no leaking point; big flow and the flow can be adjusted by changing the air pressure; unique structure of valve, no blind point, good self-priming,no necessary to fill the liquid. The auto switch is available,which enables the pump stop without water,and automatically turning on with water. This serial of diaphragm pump is the best choice of transporting liquid ,food, petroleum and other liquid. Can be used with starting rock bolt machine and hand drill in the working face, which eliminates the danger of using electricity.
