The Onga MB25L Miniblaze is a compact petrol engine-driven water transfer pump designed for light-duty applications such as firefighting support, irrigation, water transfer, and spray units. Its lightweight and portable design makes it ideal for ute-mounted systems and field operations where quick deployment is required.
This horizontal single-stage centrifugal pump features a closed impeller design and is constructed using corrosion-resistant materials. The pump casing is made from powder-coated aluminium, while the impeller is manufactured from 30% glass-filled nylon for durability and efficient performance. Additional components such as aluminium diffuser, nitrile seals, and carbon/ceramic mechanical sealing ensure reliable operation when handling clean, non-aggressive water.
Based on the model performance data, the MB25L delivers a maximum flow of 215 L/min at low head conditions and achieves a maximum head of 21 metres at shut-off. The performance curve shows progressive reduction in flow with increasing head, including 184 L/min at 5 metres and 125 L/min at 15 metres, ensuring predictable operation across varying working conditions. :contentReference[oaicite:0]{index=0}
