BQG Series 140L/min Pneumatic Diaphragm Pump Air-operated diaphragm pumps 1.5 inch inlet/Outlet diameter
The BQG series of pneumatic diaphragm pumps for mining applications is an innovative, high-performance device specifically tailored for the mining and industrial sectors. Driven by compressed air, these pumps use a unique pneumatic system to ensure stable liquid transfer without leaks or contamination. Key components are made from high-strength aluminum alloy, while diaphragms and valve balls are crafted from specialized materials for superior wear resistance and corrosion protection. The pump's dead-point-free and anti-stall design ensures efficient operation even in complex conditions. Suitable for mine dewatering, tunnel engineering, oil, and chemical industries, the BQG series is particularly well-suited for long-term use in harsh environments.
