Choose a pump for agriculture or irrigation by the water source, the head it must lift, the flow you need, the power you have and the hours it will run. Domestic water pumps follow the same logic at smaller scale, with more weight on quiet running and automatic control.
The same checklist applies to pumps for irrigation in Africa, where power supply and spare parts often decide the choice more than the pump's rating.
Start with the water source
The source narrows the pump type at once. A deep borewell needs a submersible pump, a shallow well or open canal can use a surface or monoblock pump, and a river or tank supply may suit a centrifugal pump on the bank.
Measure the water level, the depth to the pump, the lift to the field or tank and the pipe length. Together these give the total head. Our guide to pump curves, head and flow shows how to match a pump to the head.
Add a margin for pipe friction and for the drawdown of the well during pumping. A pump chosen for the static level alone will deliver less water than you planned once it runs for a few hours.
Match the pump to the use
Each use has its own priorities:
- Field irrigation needs high flow at moderate head, long hours and a pump that tolerates some sand. Sprinkler and drip systems also need pressure.
- Livestock and farm yard supply needs steady flow at low to medium head, usually into tanks.
- Household water needs a pump that starts and stops often, runs quietly and has a pressure switch or tank.
- Deep wells for village supply need a submersible pump with enough head and a motor sized for continuous duty.
Check the power supply
Power is where many projects go wrong. Confirm voltage, phase and frequency before you order. A pump built for 50 Hz three-phase power will not run correctly on a single-phase or 60 Hz supply without changes. Read about single-phase vs three-phase pumps before you decide.
Where grid power is weak or absent, options include diesel-driven pumps or solar pumps from Gujarat. Unstable voltage damages motors, so ask the supplier about protection.
Think about water quality and materials
Sand, silt, salt and low pH wear pumps fast. For sandy borewells, ask for sand-handling impellers and check the water for abrasives. For corrosive water, specify stainless steel or suitable plastic parts. Ask the supplier which materials the wet parts use and what each tolerates.
Fit a strainer to the intake and match the filter and the foot valve to the source, since most field failures start with air leaks or debris at the intake.
Plan for service and spares
A pump on a remote farm cannot wait weeks for a seal. Ask for spare parts lists, stock the wearing parts and make sure local technicians can rewind or replace motors. Our guide to choosing the right pump will help you build the spec.
