The Farmmaster OJ series are the flagship of the Onga range, offering performance, efficiency and reliability in a solid cast iron casing. These pumps have evolved with the needs of Australian farmers and landowners since Onga's beginnings in 1967. They have benefited from over 35 years of outstanding pump engineering.

The OJ range perform reliably in almost any situation - whatever you need to do with water, you can rely on an Onga OJ. They are perfect for drawing water from any convenient source and taking it where you need it. Their tall design means that the impeller is never operating in air, so priming is never a problem.
