Its single impeller configuration is engineered to deliver strong flow output with stable pressure, making it suitable for medium-distance pumping and rapid water delivery in field conditions.\u003c\/p\u003e\r\n\r\n\u003cp\u003eConstructed using marine-grade aluminium across the pump casing, impeller, diffuser, pump cover, and discharge components, the B2-48Y provides excellent corrosion resistance, structural strength, and reduced overall weight for portability. The advanced hydraulic design improves flow efficiency while maintaining reliable operation. Internal sealing components include a carbon\/ceramic mechanical seal, NBR O-rings, and an EPDM non-return valve to ensure long-term durability and leak-free performance.\u003c\/p\u003e\r\n\r\n\u003cp\u003eBased on the performance curve for the B2-48Y model, the pump delivers a maximum flow of approximately 550 L\/min at low head conditions and achieves a maximum head of approximately 45 metres. It also supports a maximum suction lift of 8 metres, allowing efficient water draw from tanks, dams, and open sources.\u003c\/p\u003e\r\n\r\n\u003cp\u003eThe unit is powered by a Yanmar L48N 5.5 HP diesel engine with 219 cc displacement, operating at up to 4000 RPM. It features a 2.4-litre fuel tank and uses SAE30 oil with a capacity of 0.8 litres, supporting continuous-duty operation with reliable fuel efficiency and field-ready performance.\u003c\/p\u003e\r\n\r\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eEngine: Yanmar L48N Diesel Engine, 5.5 HP, 219 cc\u003c\/li\u003e\r\n\u003cli\u003eMaximum Flow: approx. 550 L\/min\u003c\/li\u003e\r\n\u003cli\u003eMaximum Head: approx. 45 m\u003c\/li\u003e\r\n\u003cli\u003eMaximum Suction Lift: 8 m\u003c\/li\u003e\r\n\u003cli\u003ePump Type: Single Stage centrifugal firefighting pump\u003c\/li\u003e\r\n\u003cli\u003eConstruction: Marine-grade aluminium casing, impeller, diffuser, and discharge\u003c\/li\u003e\r\n\u003cli\u003eMechanical Seal: Carbon \/ Ceramic\u003c\/li\u003e\r\n\u003cli\u003eO-Rings: NBR with EPDM non-return valve\u003c\/li\u003e\r\n\u003cli\u003eFuel Tank Capacity: 2.4 litres\u003c\/li\u003e\r\n\u003cli\u003eRecommended Oil: SAE30, Oil Capacity: 0.8 litres\u003c\/li\u003e\r\n\u003cli\u003eMaximum Liquid Temperature: 55°C\u003c\/li\u003e\r\n\u003cli\u003eMaximum Ambient Temperature: 40°C\u003c\/li\u003e\r\n\u003cli\u003eMaximum Operating Pressure: 16 bar\u003c\/li\u003e\r\n\u003cli\u003eInlet Size: 40 mm\u003c\/li\u003e\r\n\u003cli\u003eOutlet Size: 40 mm + 2 x 25 mm\u003c\/li\u003e\r\n\u003cli\u003eAdvanced Self-Priming Capability for rapid operation\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Onga","offers":[{"title":"Default Title","offer_id":50703665332471,"sku":"B2-48Y","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/onga-b2-48y-marine-grade-aluminium-high-flow-single-stage-firefighting-pump.png?v=1776852591","url":"https:\/\/foundationpumps.com.au\/products\/onga-b2-48y-marine-grade-aluminium-high-flow-single-stage-firefighting-pump","provider":"Foundation Pumps","version":"1.0","type":"link"}
