Irrigation pumping is defined by two things: the water is usually taken from an open source, and the system depends on maintained line pressure rather than raw volume. Abstraction from a river, lake or reservoir means the intake carries silt and vegetation, while distribution across a scheme means friction loss across long runs often exceeds the static lift.
River and reservoir intakes carry silt, weed and debris regardless of screening. Where the water reaching the pump is not reliably clean, solids handling is not optional — the B Series passes 44 to 124 mm depending on model.
Centre-pivot, sprinkler and drip systems all depend on pressure at the emitter, not volume at the pump. The K Series is built for this: heads to 145 m on the K200 at 1,300 m³/hr, with the K300 trading head for volume at 2,300 m³/hr and 85 m for wider distribution at lower lift.
Irrigation load follows the growing season and the weather, so pumps sit idle and then run hard. Automatic self-priming to 8.5 m means a unit that has stood through a dry spell restarts without manual priming.
Agricultural abstraction points are rarely near a supply. Diesel packages allow pumping at the water source rather than running cable to it; electric drive suits fixed installations where supply already exists and running cost dominates.
Selections below are based on the published specifications for each range.
Mains charging, pressure boosting and distribution where the water has been settled or filtered. Heads to 145 m. No solids rating, so it belongs downstream of the intake rather than at it.
Abstraction directly from rivers, lakes and reservoirs, where the water carries silt and vegetation. Flows to 3,350 m³/hr with solids handling to 124 mm.
Split the system at the point where the water becomes clean. A B Series unit at the intake and a K Series unit on the distribution side is usually a better answer than one pump asked to do both.
Size on total head including friction loss across the full distribution run. On large schemes this can dominate the calculation, and a pump chosen on lift alone will not hold pressure at the far emitters.
Where the head requirement exceeds 145 m — long uphill runs to elevated storage, for instance — the L Series is the only range that reaches it.
Usually not. Water at the intake carries silt and vegetation and needs the B Series' solids handling; distribution needs the K Series' pressure, to 145 m. Splitting the system where the water becomes clean is generally a better answer than one pump doing both.
The K Series is built for it. The K200 gives 1,300 m³/hr at 145 m for higher-pressure zones, while the K300 trades head for volume at 2,300 m³/hr and 85 m for wider distribution at lower lift.
Yes. Automatic self-priming to 8.5 m means a unit that has stood idle draws water again without manual priming, and without a foot valve or external vacuum pump.
