The Onga B2-55H Blazemaster 2 is a high-performance petrol engine-driven firefighting pump designed for emergency response, rural water transfer, irrigation, and tank filling applications. Its portable design and reliable operation make it ideal for use in remote locations where electrical power is unavailable.
Built with marine-grade aluminium across the pump casing, impeller, diffuser, and discharge components, the B2-55H offers superior strength and corrosion resistance. The closed impeller design enhances hydraulic efficiency, delivering strong flow rates with consistent pressure. High-quality internal components including a carbon/ceramic mechanical seal and NBR O-rings ensure durability and leak-free performance under demanding conditions.
Based on the performance curve for the B2-55H single-stage model, the pump delivers a maximum flow of approximately 600 L/min at low head conditions and reaches a maximum head of approximately 59 metres at shut-off. It also supports a maximum suction lift of 8 metres, enabling efficient water draw from tanks, dams, and natural water sources.
The unit is powered by a Honda GX160 5.5 HP 4-stroke petrol engine, known for reliability, fuel efficiency, and smooth operation. It operates at 3000 RPM and is designed for continuous duty. The engine features a 3.1-litre fuel tank and uses 10W/30 API SG oil, making it well-suited for extended field operations.
