Irrigation Pumps
Irrigation pumps deliver the reliable flow and pressure needed to feed sprinklers, drip lines, and agricultural irrigation networks from tanks, wells, rivers, and reservoirs. Correct pump selection keeps crops, gardens, and sports surfaces watered efficiently.
What is an Irrigation Pump?
An irrigation pump is a surface or submersible pump sized to deliver a specific flow at the pressure required by the irrigation equipment it feeds. Applications range from single-sprinkler garden systems to multi-zone commercial and agricultural installations.
How it works
- The pump draws water from a tank, well, borehole, or open water source.
- The impeller generates the pressure required by the irrigation network.
- Water distributes through pipework to sprinklers, drippers, or rain guns.
- Automatic controls start and stop the pump with irrigation demand or timers.
Where are Irrigation Pumps Used?
Agriculture & Horticulture
Field, polytunnel, and nursery irrigation duties.
Gardens & Landscaping
Domestic sprinkler and drip irrigation systems.
Sports Grounds
Pitch and green irrigation at consistent pressure.
Rainwater & Tank Systems
Pumping stored water to points of use.
How to determine which Irrigation Pump is the one you need?
Required Flow
Sum the demand of all simultaneously operating sprinklers or zones.
Operating Pressure
Sprinklers typically need 2 to 4 bar; drip systems need less.
Water Source & Lift
Surface pumps for shallow sources; submersibles for depth.
Automation
Pressure controllers and timers enable unattended irrigation.
Comparing Types of Irrigation Pumps
Surface Irrigation Pumps
Self-priming centrifugal pumps beside the water source.
Submersible Irrigation Pumps
In-tank and borehole pumps for deeper sources.
Multistage Pressure Pumps
Higher pressures for long runs and multiple zones.
Engine Driven Pumps
Petrol and diesel units for sites without power.

FAQs
What pressure do sprinklers need?
Most impact and gear-drive sprinklers perform best between 2 and 4 bar; always check the manufacturer's specification.
How do I size an irrigation pump?
Add together the flow of every device operating at once and determine the pressure required at the furthest point, allowing for pipe friction losses.
Can I pump from a river or stream?
Physically yes, with an appropriate strainer and suction arrangement, but abstraction may require a licence from the environmental regulator.
Why does my irrigation pressure drop in summer?
Higher demand, falling source levels, and clogged filters commonly reduce summer performance; regular maintenance helps.
Should I choose a surface or submersible pump?
Surface pumps suit sources within about 8 metres of lift; deeper wells, boreholes, and tanks favour submersible pumps.
Troubleshooting your Irrigation Pump
Pump loses prime: Check the foot valve, suction joints, and source water level.
Pressure lower than expected: Clean filters, check for leaks, and verify the duty against demand.
Pump overheating: Ensure adequate flow through the pump and correct motor ventilation.
