Submersible Well Bore Pump
Description
The Submersible Solar Bore Pump range provides a practical off-grid solution for pumping water from bores, wells and remote water sources. Designed to run directly from compatible solar panels, these brushless DC pumps can move water over long distances and to significant heights without requiring grid power or a battery bank.
With models offering up to 16m³/hr flow and up to 170m maximum head, the range suits everything from livestock watering and tank filling to domestic water supply and remote farm applications.

Submersible Solar Bore Pumps with MPPT Controller
Off-Grid Water Pumping Without a Battery Bank
These submersible bore pumps are designed for direct connection to a correctly sized solar array, making them ideal for remote locations where grid electricity is unavailable or impractical.
When sufficient sunlight is available, the integrated controller powers the pump automatically. This makes the system well suited to applications such as livestock watering, tank filling, remote irrigation and off-grid domestic water supply.
Integrated MPPT Smart Controller
Each pump incorporates an intelligent MPPT controller designed to make efficient use of available solar power across a range of input voltages.
The controller also provides:
- Soft-start operation
- Under-voltage protection
- Over-voltage protection
- Locked-rotor protection
- Automatic restart when operating conditions return to normal
This allows the pump to operate automatically as solar conditions change throughout the day.
Brushless DC Motor
The pumps use a brushless DC motor, eliminating the wear components associated with conventional brushed motors and helping provide reliable long-term operation in remote installations.
The motor is oil cooled and designed for continuous submerged operation. Because the surrounding water assists with cooling, the pump must remain correctly submerged during operation.
3" & 4" Bore Pump Options
The range includes compact 3" models for narrower bore installations as well as larger 4" models for applications requiring higher flow or head.
Some 3" models are approximately 76mm in diameter, making them useful for retrofitting into existing narrow bores and wells where larger pumps may not fit.
Screw vs Impeller Pumps
The range includes both screw-type and multi-stage impeller pump designs.
Screw-type models are well suited to applications requiring relatively high head at lower flow rates, while impeller models provide higher flow options for tank filling and broader water-transfer applications.
High Head & Long-Distance Water Transfer
Depending on the model selected, maximum head ranges from approximately 35m to 170m.
Maximum head represents the theoretical vertical height the pump can generate at zero flow. Actual system performance will be lower once pipe friction, fittings, elevation and required flow rate are taken into account.
For best results, select a pump based on both the total dynamic head of the system and the required water flow.
Solar Panel Sizing
As a general guide, the solar array should provide approximately 1.5–2 times the motor power rating to support good pump performance under real-world solar conditions.
The solar array voltage should also be selected to suit the pump's specified design voltage and MPPT input range.
Performance generally improves as the available solar voltage and power approach the pump's intended operating conditions.
Stainless Steel Construction
The pumps use 304 stainless steel external components for durability in submerged applications. Selected models also use stainless steel hydraulic components designed for long service life.
Each pump is factory tested for leakage and operating performance before supply.

Solar Water Pump Accessories
Scintex can also supply components commonly used when building solar bore and water-transfer systems:
Important: Pump selection should be based on required flow, bore depth, static and dynamic water level, elevation change, pipe length and friction losses. Maximum flow and maximum head do not occur at the same operating point. Always ensure the pump remains adequately submerged during operation and confirm the solar array voltage remains within the specified MPPT input range.
