Wells & boreholes
Lift groundwater from boreholes and deep wells with a system matched to flow, total head and well conditions. HOBER helps match the deep-well pump, the solar pumping inverter or controller and the PV configuration for distributors, installers and water supply projects.
A borehole solar pumping installation
The system
A deep-well solar pumping system converts solar energy into controlled pump operation and delivers groundwater where it is needed.
The pump models, their figures and their curves are published with the range. The pump is matched into the system as a whole, together with the drive and the array.
The system
The right architecture depends on project size, pump requirements and available power source.
Use a standard AC deep-well submersible pump together with a HOBER solar pumping inverter. Suitable for distributors, installers and larger projects requiring flexible pump selection and wider system configuration.
System flow
Power options
A compact solar pumping solution using a BLDC submersible pump and its dedicated solar pump controller. Suitable for small and medium off-grid water supply applications.
System flow
Engineering challenge
The hole the pump has to fit decides the pump, and the pump decides the drive and the array behind it.
A deep-well system is not selected on pump power. The borehole the pump has to go down, the level the water stands at, the flow the project needs and the head the water has to be lifted through decide the pump — and what comes back up the same hole has to arrive at the delivery point. A pump chosen on power alone is a pump chosen without the project.
The pipe friction loss calculator works out total dynamic head from the static head, the pipe friction loss and the fittings loss.
Project data
The figures the pump, the drive and the array are matched on, and where each one is read.
System matching
HOBER reads the well and the duty point against the range and matches the pump, the drive and the array to them.
Example
The figures are an illustrative example of how a project is read, not a product claim: the pump follows the borehole and the duty point.
Product data
The models, the technical specifications and the performance curves are published series by series. The pump range is organised by the water source it serves, and each series states its own models, figures and Q-H curve.

Applications
Reliable groundwater supply for farms and irrigation systems.
Solar-powered groundwater supply for remote livestock operations.
Pump groundwater into storage tanks for community water supply.
A larger water supply project: the array on its mounting frame.
Installations
Photographs of HOBER equipment on site.
Support
The pump is only one part of a reliable deep-well solar pumping system.
HOBER works on the system rather than the pump alone, from the project data to commissioning.

Borehole installations and the settings a deep-well system is commissioned with.
Deep-well projects
Send us the borehole and the water requirements. HOBER can help match the deep-well pump, the solar pumping inverter or controller and the PV configuration for your project.
Project inquiry
For distributors, installers and project contractors. Any figure may be left open — what is missing we confirm with you before the system is quoted.
