BQG series mining pneumatic diaphragm pump is a high-quality, forward-displacement, self-suction pump. It uses compressed air, commonly used in industrial and mining enterprises, as its power source. It uses pressure difference in the air chamber alternatively to produce suction liquid pressure and positive liquid pressure in the liquid chamber. The one-way control ball valve switch ensures the forward flow of liquid.
The pump features a no-dead-point, anti-stall design and modular pneumatic body/flow parts. Key parts are made of aluminum alloy casting, with diaphragms, balls, and ball seats made of advanced international materials to ensure small size, light weight, low noise, and reliable operation. It is especially suitable for field works in mines, tunnels, petroleum, and chemical industries.
