Reliable pumps for sprinkler systems, drip irrigation, hose reels, polytunnels, allotments, market gardens and agricultural watering. Whether you're drawing from a borehole, well, rainwater tank, storage reservoir or open watercourse, we supply borehole pumps, well pumps, surface pumps and high-flow transfer pumps suited to irrigation use across domestic, horticultural and agricultural settings.
Irrigation water pumps move water from a source to where it's needed, whether that's sprinklers, drip irrigation, hosepipes or agricultural spray systems.
Choosing the right pump comes down to three things: your water source, how far the water needs to travel, and the pressure and flow your system requires.
Use the selector below (or read the buying guide further down) to find a pump that matches your setup.
A few quick questions about where your water comes from and what you're watering. We'll match you to the right pump from our range, with the head and flow it needs to perform reliably.
This helps us understand whether you need a continuous-duty pump for sprinklers, a demand pump for occasional use, or a high-flow transfer pump for moving water across land.
The source determines whether you need a submersible pump, a surface pump, or a specific borehole-format pump.
Some pumps run continuously when switched on. Others activate automatically when you open a tap, trigger or sprinkler valve.
For pressurised irrigation, we need three numbers to pick the right model from the recommended range. If you're not sure, give your best estimate and we'll flag any concerns in the results.
Where water is taken from rivers, lakes, ditches or reservoirs, a submersible transfer pump such as the APP KHL-20 is often the right solution.
These pumps sit directly in the water and are designed to move large volumes over distance. They prioritise flow rate rather than pressure, so they suit agricultural irrigation, field watering, and moving water across land where debris and sediment may be present.
The deeper read: what's in this range, how to pick, and when to talk to us before you buy.
Borehole pumps are designed for narrow, drilled shafts that access groundwater at depth. Their slim design and multi-stage impellers allow them to generate high pressure, making them ideal for lifting water vertically and pushing it over long distances.
They are typically used for:
If you need a high pressure irrigation pump or a pump for deep boreholes, this is usually the right option.
Well pumps are used in wider shafts, wells, tanks and cisterns. They provide a balance between flow and pressure, making them suitable for domestic and small commercial irrigation.
The Divertron is a common choice for this type of setup. It automatically switches on and off when a tap or hose is opened, making it ideal for garden watering and general use. However, it is not typically suited to running sprinkler systems where consistent pressure is required.
These pumps are often used for:
Surface pumps sit outside the water source and draw water in through a suction hose. They are easy to install, access and maintain.
They are commonly used for:
The FL Demand Pump is often used by councils and contractors with battery-powered bowsers for watering plants in public spaces. It automatically switches on and off when a trigger or valve is opened and closed, making it efficient and easy to use. With its high head, it performs well over distance and can be used with a standard hosepipe.
If you’re looking for a 12V irrigation pump or battery powered water pump, this is a typical setup.
Where water is taken from rivers, lakes, ditches or reservoirs, a submersible transfer pump is often the right solution.
These pumps sit directly in the water and are designed to move large volumes over distance. They prioritise flow rate rather than pressure, making them suitable for:
The APP KHL-20 is a good example of this type of pump, designed for moving high volumes from open water sources where debris and sediment may be present.
To select the right irrigation pump, focus on three key questions:
1. Where is your water coming from?
Borehole, well, tank or open water will determine the pump type.
2. How far does the water need to travel?
Consider both vertical lift and horizontal distance.
3. What pressure and flow are required?
Sprinklers, drip systems and spray nozzles all require specific performance levels.
Matching these requirements to a pump’s performance curve ensures reliable operation.
