Diaphragm Pump Introduction:
Pneumatic diaphragm pump is a kind of no electricity, the use of compressed air in submersible pump power. This pump is not affected by environmental impact, such as power supply, moisture, safety performance is high, particularly applicable to flammable and explosive work environment, etc.
Pneumatic diaphragm pump features:
1, oil-free air chamber, avoid lubrication
2, pressure chamber plastic material under 25, more than 25 adopt aluminum alloy material, corrosion resistance, suitable for high pollution situations
3, low pressure, slow motion, no card machine
4, corrosion resistance, long life of diaphragm
5, less parts, easy assembling

Technical characteristics:
Mine pneumatic diaphragm pump with currents reciprocating the reversing valve core, make the compressed air around alternately into the cavity, to push the diaphragm is concave and convex reciprocating movement and make the working chamber to produce differential pressure, reach the purpose of absorbing water and drainage. Small volume, light weight, no roots, can be used as portable pump, without lubrication, the main valve of air without special requirements, can be self-priming is up and running.
working principle:
Mine pneumatic diaphragm pump using the air chamber pressure difference of alternating suction fluid pressure in the liquid chamber and liquid pressure, control valves, liquid can be sure of positive flow. After aeration, the pump starts running, and a continuous work to ensure that the required pressure remains constant, the pump will increase and maintain the pipeline pressure, and the maximum duct pressure (or distributing valve closed), will cease to work, and when necessary, restore pumping.
