★ Product Description: BQG series of mine pneumatic diaphragm pump is our own innovation, independent research and development, with independent intellectual property rights of the new pneumatic products, technology has reached the international advanced level. BQG series of mine pneumatic diaphragm pump is a high quality positive displacement pump, it is commonly used in industrial and mining enterprises of compressed air as a power source, produces alternating suction fluid pressure difference and being liquid in the liquid chamber by the gas pressure in the chamber Pressure control check valve switch to ensure positive flow of fluid. The pump has no dead spots, stall resistant design, modular pneumatic pump / fluid section, effective solution to the original diaphragm valve member movement is not in place and other technical problems. Pneumatic diaphragm pump is a new transportation machinery, the product core components made of aluminum alloy diaphragm, ball and tee adopting international advanced materials made with light weight, small size, low noise, easy to operate, reliable, corrosion wear, corrosion resistance, fire, explosion, etc. Especially suitable for mine, tunnel, tunnel engineering and petroleum and chemical industry, at the same time, pneumatic diaphragm pumps also have a submersible pump, pump, trash pump, shield pump, mud pump and other functions, a wide range, can meet different users, transport needs of different media, it has become silent pneumatic submersible pumps main alternatives. ★ Environmental conditions: a) any transfer of flowable materials, media concentration (by volume) must not exceed 15%; b) the maximum diameter of the solid particles containing not more than 9mm; c) Operating ambient temperature (5 ~ 50) ℃; d) PH transport medium in the range of 6 ~ 8; e) transmission medium temperature does not exceed 50 ℃; f) apply pressure range 0.4MPa ~ 0.8MPa. ★ Advantages and features: 1, energy consumption, energy saving; 2, small size, light weight, easy operation, wide application; 3, pure pneumatic products, safe and reliable; 4, no-load, overload operation, the device without injury; 5, reciprocated without pause, high efficiency.
