Submersible Well Water Pump Selection for Solar Pumping Projects
SolarSeeker helps pump dealers, irrigation contractors, EPC buyers and OEM partners select the right well pump by duty point, then match it with the appropriate SolarSeeker inverter, controller or custom cabinet.
Use this page when you need the pump-selection path first. If you already know the pump voltage, phase, head and flow, SolarSeeker can check whether the project should use SP6, a PV pump controller, SP4 or a custom cabinet, and can help verify the PV and field-accessory requirements.

What is a submersible well water pump?
This pump sits inside the well or borehole and pushes water up through the pipe. In solar pumping projects, the pump must be selected together with head, flow, water level, cable length, PV input and the controller or inverter that will run the motor.
Need Pump Body?
Start here when the buyer needs a pump for a borehole, farm well, livestock tank or rural water source.
Need Protection?
Use SP6 when a protected submersible pump controller is needed for outdoor or harsh field sites.
Need AC Pump Drive?
Use SolarSeeker solar pump inverters when an AC pump must run from PV power with MPPT control.
Need System Matching?
Use system matching guidance when the project needs the pump, PV array, inverter or controller, cabinet and field accessories checked together before sourcing and installation.
Product Path
Choose the pump path before choosing the controller
A well pump inquiry usually starts with water demand, but the final product path depends on whether the buyer already has a pump, needs only a protected controller, or needs the whole system checked for compatibility.

What data is needed to size a submersible water pump for wells?
Do not choose a well pump only by horsepower. Two pumps with the same kW can deliver very different water volume depending on head, pipe loss and motor speed.
Send Sizing Data1. Well Depth and Water Level
Send static water level, dynamic water level and total well depth. Dynamic level matters more than the number printed on the well.
2. Total Head
Confirm vertical lift, distance to tank, pipe diameter, elbows and pressure demand so the pump curve can be checked correctly.
3. Flow Rate
Share required m3/h, L/min or daily water volume. Irrigation projects often need higher peak flow than household wells.
4. Voltage and Phase
Tell us whether the pump is DC, 220V single phase, 220V three phase or 380V three phase. This decides the controller or inverter path.
5. Site Environment
Hot, dusty, humid or outdoor sites may need a protected controller, a solar pump cabinet or extra surge protection.
6. Buyer Type
Distributors may need OEM packing and repeatable models. EPC buyers usually need project matching, wiring guidance and commissioning support.
First Screening Table
Match the submersible pump with the right solar product
Use this table for the first discussion. Final selection should still confirm pump curve, cable length, PV array, controller rating and protection requirements.
| Buyer Situation | Typical Pump Need | Key Check | SolarSeeker Path |
|---|---|---|---|
| Pump dealer replacing a borehole pump | Pump body selected by existing pipe and well data | Head, flow, pump diameter, voltage and cable length | Send pump data |
| Installer needs outdoor pump control | Submersible pump plus protected controller | Dry-run, tank level, enclosure and wiring protection | SP6 controller |
| Farm project with 220V or 380V AC pump | AC submersible pump driven by solar inverter | Motor phase, rated current, MPPT range and PV array size | Solar pump inverter |
| EPC buyer needs system matching | Pump, PV array, inverter/controller and accessories checked together | Daily water target, supply scope and installation requirements | System design review |
| Deep well water supply project | High-head pump with full system planning | Dynamic water level, pipe loss, tank height and runtime | Deep well solution |
Where It Fits
Common uses for submersible water pumps for wells
The same pump family can serve different water jobs, but the sizing logic changes with well depth, tank height, irrigation flow and field environment.
Deep Well Water Supply
For boreholes, village wells and remote water tanks where reliable lifting is more important than low initial cost.
Open solutionFarm Irrigation Wells
For fields that need stable flow during sunny hours and may require 220V or 380V AC pump matching.
View irrigation pathLivestock Water Supply
For tanks in remote farms where dry-run protection, level control and simple maintenance matter.
View livestock pathRemote Off-Grid Supply
For villages, island sites and areas where grid power is unstable or diesel fuel is expensive.

Submersible well water pump FAQ
These are the questions SolarSeeker usually checks before recommending a pump path and matching the inverter, controller, cabinet and PV requirements.
Can I choose a well pump only by horsepower?
No. Horsepower or kW is only one part of selection. The pump must also match total head, flow rate, dynamic water level, pipe loss, voltage, phase and the controller or inverter rating.
What information should I send for a pump recommendation?
Send well depth, static and dynamic water level, required flow rate, pipe distance, tank height, pump voltage, pump phase, site country and whether a pump is already selected or you still need pump-selection and system-matching guidance.
When should I use SP6 instead of only selecting a pump?
Use SP6 when the site needs a protected submersible pump controller with dry-run protection, tank level control and outdoor installation support. If the buyer only asks for a pump body, start with the pump duty point first.
When should the whole solar pumping system be checked together?
Check the whole system together when the pump, PV array, inverter or controller, cabinet and accessories must work as one design. SolarSeeker supplies inverter, controller and custom-cabinet products and can help verify the pump, PV and field-accessory requirements.
Does SolarSeeker supply pump matching for Southeast Asia projects?
Yes. SolarSeeker supports pump dealers, irrigation contractors, distributors and EPC buyers in Southeast Asia and other regions with pump matching, inverter or controller selection, system matching and installation guidance.

Head and flow target
Required flow rate, pipe distance, elevation and daily water demand decide pump duty.
Existing pump data
If a pump already exists, send voltage, phase, power, current and a nameplate photo.
Water source and country
