Brushless DC Solar Water Pump

The Suntrica 3DPC brushless DC solar water pump series is a 3-inch submersible clean-water range for wells, boreholes, storage tanks, irrigation and livestock watering. The models listed on this page use 24V or 48V DC motors with rated power from 210W to 600W.

The listed models cover maximum flow values from 1.5 to 2.5 m3/h and maximum head values from 35 to 65 m. Maximum flow and maximum head are separate pump-curve endpoints, so the final model must be selected at the required operating flow and total dynamic head. A compatible solar pump controller is required; batteries are not required for properly configured daylight pumping.

Brushless DC motor for stable and efficient operation
Suitable for solar-powered off-grid pumping systems
Reliable clean water delivery for daily use
Low maintenance and long service life
Ideal for household, farm, and irrigation applications

How the System Works

The brushless DC solar water pump works with solar panels through a dedicated controller. The controller helps regulate input power, protect the motor, and maintain stable pumping performance under varying sunlight conditions.

Solar panel provides DC power input
Controller manages pump startup and protection
Pump lifts water from well or borehole
Water level control can be added if needed
System can be configured based on project demand

How to Choose the Right Model

Before selecting a model, customers should confirm required flow, lifting head, well depth, water level, and daily water demand. Proper model matching ensures stable pump performance and better solar energy utilization.

The correct solar panel voltage and controller configuration are also important to ensure efficient operation and long-term system reliability.

Check actual water level depth
Measure required lifting head accurately
Confirm required daily water volume
Match solar panel voltage and power correctly
