BQG Series 320L/min Pneumatic Diaphragm Pump Air-operated diaphragm pumps 3 inch inlet/Outlet diameter

The BQG series of mine-specific pneumatic diaphragm pumps are advanced products developed by our company for mining and industrial applications. Utilizing compressed air as the power source, these pumps achieve positive displacement self-priming through pressure differentials in the air chamber, ensuring stable operation and leak-free transfer. Constructed from lightweight aluminum alloy and high-performance materials, the BQG series offers excellent wear resistance, corrosion protection, fireproof, and explosion-proof properties. Suitable for mine dewatering, tunnel engineering, oil, and chemical industries, this pump excels in harsh environments and is an ideal choice for modern mining operations.
