Onga 148 Series 1.80kW 240v Closed Coupled High Flow Centrifugal Pumps (Max 400LPM/350kPa)

The Onga 148 Series is a high-performance, close-coupled centrifugal pump designed to deliver exceptional flow rates and reliable operation for demanding water transfer and circulation tasks. Powered by a 1.80kW TEFC motor and engineered with a Hi-Flo impeller, this model achieves up to 400 L/min and 350 kPa, making it ideal for applications requiring both high flow and moderate pressure.

Its 20% glass-filled Noryl pump casing offers excellent corrosion resistance, while precision-moulded polycarbonate impellers ensure efficiency and long service life. An inbuilt thermal overload protects the motor from overheating, and the close-coupled design reduces footprint for easier installation.

Whether for large-scale irrigation, tank filling, agricultural water movement, or wash-down duties, the Onga 148 delivers dependable, cost-effective performance.
