The Onga B2-90H Blazemaster 2 is a high-pressure petrol engine-driven firefighting pump designed for demanding emergency response, irrigation, water transfer, and tank filling applications. Built for portability and consistent field performance, this single-stage pump is ideal for operations where reliable water delivery is critical and power supply is unavailable.
Engineered with marine-grade aluminium construction across the pump casing, impeller, diffuser, and discharge components, the B2-90H offers excellent strength, corrosion resistance, and lightweight handling. The closed impeller hydraulic design enhances pressure generation while maintaining efficient flow characteristics. High-quality internal components, including a carbon/ceramic mechanical seal and NBR O-rings, ensure durability and leak-free operation under continuous use.
Based on the performance curve for the B2-90H single impeller model, the pump delivers a maximum flow of approximately 720 L/min at low head conditions and achieves a maximum head of approximately 65 metres at shut-off. It also supports a maximum suction lift of 8 metres, enabling efficient water extraction from tanks, dams, and open water sources.
The unit is powered by a Honda GX270 9 HP 4-stroke petrol engine operating at 3000 RPM, providing strong and reliable performance for high-demand applications. With a 5.3-litre fuel tank and 10W/30 API SG oil compatibility, the engine is suitable for continuous duty and extended operational use.
