The Onga B2-70Y Blazemaster 2 is a single stage diesel engine-driven firefighting pump designed for high-capacity water transfer, irrigation, and emergency response applications. Its single impeller configuration is optimized to deliver high flow rates with stable pressure performance.
Constructed using marine-grade aluminium across the pump casing, impeller, diffuser, and discharge components, the pump offers superior corrosion resistance and durability. The advanced hydraulic design enhances flow efficiency while maintaining consistent performance under demanding operating conditions. Internal sealing is ensured using a carbon/ceramic mechanical seal, NBR O-rings, and an EPDM non-return valve.
Based on the performance curve, the pump delivers a maximum flow of 723 L/min at low head conditions and achieves a maximum head of approximately 47 metres. It also supports a suction lift of up to 8 metres for efficient water sourcing.
The unit is powered by a Yanmar L70N diesel engine, providing reliable output, fuel efficiency, and dependable performance in field applications.
