The Onga BM65H Aluminium Twin Stage Firefighting Pump is a high-pressure engine-driven pump designed for demanding firefighting, irrigation, water transfer, and spray applications. Its twin stage configuration is engineered to deliver higher pressure, making it ideal for long hose runs, elevated terrains, and applications requiring strong discharge performance.
Built with a lightweight yet robust aluminium pump casing, the BM65H provides excellent corrosion resistance while remaining portable for field use. The twin impeller system enhances pressure capability, while high-quality internal components including glass-filled impellers, nitrile seals, ceramic and carbon seal faces, and stainless steel spring elements ensure durability and long service life.
Powered by a Honda GX200 petrol engine, this pump delivers reliable and consistent performance in remote and off-grid environments. Based on model-specific performance data, it achieves a maximum flow of approx 420 L/Min under low head conditions and delivers a maximum head of approx 100 m, making it well suited for high-pressure firefighting and demanding water transfer applications.
The BM65H is designed for pumping clean, non-aggressive water without solids or fibres. It operates effectively across a wide range of environmental conditions, with performance dependent on system setup and operating head. Engine-driven operation ensures flexibility where electrical power is not available.
