NOTE: INJECTORS TO BE PURCHASED SEPERATELY (FRONT SUCTION SIDE)

The Onga FarmMaster JJ400 with 24L pressure tank is a reliable, compact jet pump system built for consistent water delivery in domestic, rural, and light industrial applications. Part of Onga’s proven Junior Jet range, it combines precision-engineered internals with a coated cast iron housing for long-lasting performance, even in demanding environments.

With its horizontal, single-stage design and closed impeller, the JJ400 pumps debris-free water efficiently. Jet and venturi assist technology ensures strong suction and pressure capability, while the 24L pressure tank minimises pump cycling for smoother operation and longer pump life.
