BQG Series 125L/min 0.4Mpa Pneumatic Diaphragm Pump Air-operated diaphragm pumps 2 inch inlet/Outlet diameter
The BQG series of mine-specific pneumatic diaphragm pumps are developed by our company for efficient industrial applications. Powered by compressed air, these pumps use pressure differences in the air chamber to achieve positive displacement self-priming. The unique dead-point-free and anti-stall design ensures stable operation, while the modular structure simplifies maintenance. Key components are cast from aluminum alloy, with diaphragms and valve balls made from high-quality materials, offering lightweight, low-noise, wear-resistant, and corrosion-resistant properties. Suitable for mine dewatering, tunnel engineering, oil, and chemical industries.
