Onga 143 Composite Centrifugal Water Transfer Pump for Irrigation & Tank Filling Systems

The Onga 143 is a composite centrifugal pump designed for irrigation, tank filling and clean water transfer. Part of the Onga 14 Series, model 314300 provides a practical pumping solution for domestic, agricultural and horticultural water systems.

Its corrosion-resistant, glass-filled Noryl casing is paired with a glass-filled polycarbonate Hi-Flo impeller for efficient water movement. Delivering flows up to approximately 455 L/min and a maximum head of 41 metres, the Onga 143 suits a variety of watering and distribution requirements.

A close-coupled, totally enclosed fan-cooled motor incorporates thermal overload protection against overheating. Single-phase operation and 40 mm threaded connections allow integration into suitable reticulation, water transfer and pressure boosting installations.
