Which pump for your system?
Garden pumps and irrigation chosen with real data: manufacturer curves and tables, calculators and sums done with published methods.
Which garden irrigation pump: calculator for wells and tanks
Enter depth, height difference and hose: the calculator estimates how much water each irrigation pump gives in your system, using manufacturers' curves.
The calculator gives estimates, not measurements: it combines the curves and values declared by manufacturers with the details of your system.
You will need:
- depth of the water level
- height of the outlet
- hose length and inner diameter
- pressure needed at the outlet
- the flow you need, if you know it

Comparisons
How we work
Manufacturer data, with the source
We use only data published by manufacturers, with a link to the document and the date we read it.
Not yet measured by us
We have not yet measured the pumps ourselves, and we say so on every page.
Never ranked by commission
Pumps are ranked by the flow estimated for your system, never by commission.
