The BQG series mining pneumatic diaphragm pump is a high-quality, forward-displacement, self-suction pump. It utilizes compressed air, common in industrial and mining enterprises, as its power source. By using pressure difference in the air chamber alternatively, it produces suction liquid pressure and positive liquid pressure, with a one-way control ball valve ensuring forward flow.
Key parts are made of aluminum alloy casting, with diaphragms and ball seats crafted from international advanced materials. This ensures small size, light weight, low noise, and reliable operation. It is wear-resistant, corrosion-resistant, fire-preventative, and explosion-proof, making it ideal for mines, tunnels, petroleum, and chemical industries.
