- 400W
- Maximum flow
- 3.5 m3/h
- Maximum head
- 50m
Hydraulic data
The catalogue lists 3.5 m3/h maximum flow and 50m maximum head. These are boundary values, not one simultaneous operating point. Confirm the required flow at the calculated total dynamic head before selecting the pump.
- Calculate total dynamic head from water level, elevation, pipe friction and required outlet pressure.
- Do not assume the pump delivers 3.5 m3/h at 50m head.
- Confirm the final operating point against verified performance data before ordering.
Electrical data
Configure the array for a 60V to 90V operating input while keeping total open-circuit voltage below 120V.
- Rated voltage 48V DC
- Optimum DC input voltage 60V to 90V
- PV open-circuit voltage Less than 120V
Product features
4-inch submersible pump
48V Solar Submersible Pump with Stainless Steel Impeller with 400W power, 3.5 m3/h maximum flow, and 50 m maximum head.
Stainless steel impeller
The catalogue confirms stainless steel impeller for this series. Other internal materials should not be assumed without approved technical documentation.
48V DC electrical platform
The pump is rated at 48V DC with an optimum DC input range of 60V to 90V.
Defined hydraulic limits
Catalogue limits of 3.5 m3/h maximum flow and 50m maximum head support initial model screening.
Hydraulic performance

Recommended applications
Small-volume water lifting
A potential use where the required flow and total dynamic head remain inside the verified operating range.
Solar tank filling
The 48V DC model can be evaluated for daytime tank filling after daily volume and effective solar hours are calculated.
Small irrigation water supply
It may supply a matched irrigation zone or storage tank when the required pressure and flow are confirmed.
Remote water transfer
It can be considered for off-grid transfer duties that match its electrical and hydraulic limits.
System configuration
-
Solar array
Configure the array for a 60V to 90V operating input while keeping total open-circuit voltage below 120V.
-
Compatible controller
Select a controller suitable for a 48V DC pump and the electrical limits of the complete system.

48V Solar Submersible Pump with Stainless Steel Impeller
48V Solar Submersible Pump with Stainless Steel Impeller with 400W power, 3.5 m3/h maximum flow, and 50 m maximum head.
-
Delivery line
Size the 1 1/4-inch connection, pipe route and outlet so avoidable friction does not consume available head.
Installation notes
- Confirm that the bore or casing can accept the 4-inch pump format.
- Calculate total dynamic head instead of using well depth alone.
- Keep operating input within 60V to 90V DC and array open-circuit voltage below 120V.
- Plan any cable extension and submerged connection from the supplied 2m cable length.
- Confirm the final duty point and installation details with qualified local professionals.
Product FAQ
Review verified technical data, operating limits and the project information needed to evaluate this model.
What are the verified catalogue ratings for the 4DSC3.5-50-48-400?
The catalogue lists 48V rated voltage, 60V to 90V optimum DC input, 400W rated power, 3.5 m3/h maximum flow, 50m maximum head, a 1 1/4-inch outlet, 2m cable and solar-array open-circuit voltage below 120V.
Does the pump deliver 3.5 m3/h at a 50m head?
No. Maximum flow and maximum head are opposite hydraulic boundaries and should not be treated as one operating point. The required flow must be checked at the site's calculated total dynamic head.
What solar-array voltage is suitable for this model?
The catalogue states an optimum DC input range of 60V to 90V and requires array open-circuit voltage to remain below 120V. Module configuration must satisfy both limits under local temperature conditions.
What construction does the catalogue confirm for the 4DSC3.5-50-48-400?
48V Solar Submersible Pump with Stainless Steel Impeller. The catalogue confirms stainless steel impeller for this series. Other internal materials should not be assumed without approved technical documentation.
What project data does Rakour need before confirming this pump?
Provide the water source, bore or casing diameter, static and pumping water levels, elevation, pipe length and diameter, required flow or daily volume, outlet pressure and local solar conditions.
