BQG pneumatic diaphragm pump  

Explosion proof Mining pneumatic diaphragm pump

mining pneumatic diaphragm pump is a new type of the mining pumps, it use air as it's motor, and use it's parts to change the air direction in order to let the diaphragm move to and fro.

Mining pneumatic diaphragm pump features:

1,small volume and light weight;

2,no electrical motor, there is no electric spark, used in explosion proof field safely.

3,no bearing, no need to lubrication, simple structure, easily to maintain.

4,the machine is sealed, and no reveal.

5,the material is more resistant to corrosion, also used in food,  pharmaceutical industry.

6,the flow can be changed by the air feed pressure.

7,change valve structure is special, move flexible, low air consumption.

8,self-priming is well, no need flow backward, substituting for centrifugal pump.

9,It not only used in shallow water, but also substituting for submersible  pump.
