Deep Well, High-Head or Axial Flow Pump? Choosing by Flow and Head

These three pumps are often listed together, but they solve opposite problems. The quickest way to choose is to look at two numbers: how much water you need to move, and how high you need to lift it.
| Pump | Flow | Head | Typical job |
|---|---|---|---|
| Deep well pump | Small to medium | Medium to high | Water from a drilled well |
| High-head submersible pump | Small to medium | High | Lifting water a long way up, or pushing it far |
| Axial flow pump | Very large | Low | Drainage, flood control, irrigation canals, circulating water |
Deep well pumps
Narrow enough to fit inside a borehole, with many stages to lift water from deep underground. Choose by the well diameter first, then by flow and head.
High-head submersible pumps
Multistage submersible pumps built for head rather than flow, for example to lift water from a river or tank up to a hilltop reservoir, or to feed a long pipeline.
Axial flow pumps
An axial flow pump pushes water straight along the pump axis, like a propeller in a pipe. It moves very large volumes but only to a low height. It is the pump for drainage stations, flood relief and irrigation canals, where the water only has to be lifted a few metres.
