The Onga OJ800ES Jet Assisted Water Transfer Pump is a high-performance engine-driven pump designed for applications requiring strong suction lift and reliable water delivery. It is ideal for drawing water from dams, bores, rivers, and other sources where conventional pumps cannot achieve sufficient suction performance.
Constructed with a heavy-duty cast iron pump body, the OJ800ES is built to withstand high pressures and demanding operating conditions associated with jet-assisted systems. Its robust construction ensures durability and long service life in agricultural and rural environments.
Powered by a Honda GX270 4-stroke petrol engine with electric start, the pump delivers consistent performance in off-grid applications with added ease of operation. Based on model-specific performance data, it provides a maximum flow of approx 250 L/Min and a maximum head of approx 72 m.
The jet-assisted design enables operation across varying suction depths and supports both shallow and deep well configurations. It is suitable for clean water applications including irrigation, tank filling, and water transfer where high suction lift is required.
