BQG Series 500L/min 0.2Mpa 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. Powered by compressed air, these pumps utilize a unique pressure differential in the air chamber to achieve positive displacement self-priming, ensuring leak-free and pollution-free liquid transfer. The dead-point-free and anti-stall design guarantees stable operation, while the modular structure simplifies maintenance and component replacement. Key components are cast from lightweight aluminum alloy, with diaphragms and valve balls made from high-performance materials that offer excellent wear resistance, corrosion protection, fireproof, and explosion-proof properties. Suitable for mine dewatering, tunnel engineering, oil, and chemical industries, the BQG series excels in harsh environments, making it an ideal choice for modern mining operations.
