Submersible Well Water Pump Selection for Solar Pumping Projects
Choose the right submersible well water pump by well depth, total head, flow rate, pump voltage, water demand and solar controller matching.
This page is for pump dealers, irrigation contractors, EPC buyers and OEM partners who need the pump body path, not the SP6 controller page. SolarSeeker helps match the pump with PV pump controller, inverter, cabinet and complete solar well pump kit options.

Direct Answer
What is a submersible well water pump?
A submersible well water pump is installed inside the well or borehole and pushes water upward through the pipe. It is commonly used for deep wells, rural water supply, farm irrigation, livestock watering, village water tanks and off-grid solar pumping projects.
For solar pumping, the pump body must be matched with the right controller or inverter. A correct match protects the motor, improves starting, stabilizes flow and avoids undersized solar arrays.
This page focuses on water pump selection. For protected controllers, use the SP6 submersible pump controller page. For complete packages, use the solar powered well pump kits page.
Deep Well Use
Best for wells where the pump must sit below the water level.
Head and Flow
Select by required lift height and daily water volume, not only pump kW.
Solar Matching
Pump voltage and motor phase must match the solar controller or inverter.
Protection
Dry-run, overload and water level protection reduce field failures.
Selection Table
Choose a deep well submersible pump by head and flow rate
Use this as a first screening table. Final model selection should confirm the pump curve, dynamic water level, pipe loss, cable length and solar array size.
| Project Type | Typical Well Depth | Flow Demand | Pump Path | Matched Solar Product |
|---|---|---|---|---|
| Home or village well | 20-80m | Low to medium daily water | Small submersible well pump | SP1 or pump kit |
| Farm irrigation well | 50-150m | Medium to high flow | Solar submersible pump for irrigation | SP3 or SP4 |
| Livestock water supply | 30-120m | Stable daily tank filling | Deep well submersible pump with tank control | SP6 + float switch |
| Remote off-grid water supply | 60-200m | Depends on community demand | High-head submersible water well pump | Complete kit |
| Commercial deep well | 100-300m+ | High flow and long runtime | Three-phase deep well submersible pump | SP4 + cabinet |
Sizing Factors
What information is needed to size a submersible water pump for wells?
A good pump quotation starts from water demand and hydraulic conditions. Pump power is the result of sizing, not the starting point.
Well Depth
Send total well depth, static water level and dynamic water level after pumping.
Total Head
Total head includes vertical lift, pipe friction loss, outlet pressure and tank height.
Flow Rate
Use m3/h or L/min. Daily water demand decides whether the pump must run longer or flow faster.
Voltage and Phase
Confirm whether the pump motor is 220V single phase, 220V three phase or 380V three phase.

Send well depth, head and flow before choosing a pump
For a submersible well water pump quotation, send the well depth, static water level, dynamic water level, required flow, outlet pressure, pipe distance and project country. SolarSeeker can then recommend the pump body and matched controller path.
Pump + Controller
Match the pump body with the right SolarSeeker controller
A pump page should not become a controller page, but buyers still need a clear path from pump selection to system matching.
| Pump Condition | Recommended Page | Why |
|---|---|---|
| 220V single-phase small well pump | SP1 220V Single Phase | Best for small wells, homes and small farms. |
| Three-phase pump on single-phase site | SP2 Single to Three Phase | Solves phase mismatch without changing the pump. |
| 220V three-phase commercial pump | SP3 220V Three Phase | Commercial 220V three-phase pumping path. |
| 380V three-phase deep well pump | SP4 380V Three Phase | For high-power wells, large irrigation and EPC projects. |
| Harsh well site needing protected controller | SP6 IP55 Controller | For desert, coastal, dusty or special outdoor projects. |

Submersible well water pump FAQ
How do I choose a submersible well water pump?
Choose by well depth, dynamic water level, total head, required flow rate, daily water demand, pump voltage, motor phase and the available solar array. Send the pump duty point if you already have one.
What is the difference between well depth and total head?
Well depth is the physical depth of the borehole. Total head is the real lift the pump must overcome, including dynamic water level, vertical lift, pipe friction loss and outlet pressure.
Can a normal submersible pump work with solar power?
Yes, many AC submersible pumps can work with solar power when matched with the correct solar pump inverter or PV pump controller. The pump voltage, phase, current and starting behavior must be checked first.
Should I choose a DC solar pump or an AC submersible pump?
DC solar pumps can be simple for small systems. AC submersible pumps are often better for larger wells, higher flow, existing pump replacement and projects that need standard industrial pump supply.
What information should I send for a pump quotation?
Send well depth, static water level, dynamic water level, required flow rate, pipe distance, outlet height, desired daily water volume, pump voltage preference, project country and whether you need panels and controller.
When should I use SP6 with a submersible pump?
Use SP6 when the pump system needs protected controller operation in desert, coastal, dusty, humid or special outdoor projects. SP6 is the controller path, while this page is the pump body selection path.
