Need help choosing a solar pump?
Solar Submersible Pump
Use solar power to pump groundwater. Provides a cost-effective way to supply users with safe and clean water.
Solar Surface Pump
Your preferred irrigation system. Automated systems reduce operating costs while increasing crop yields.
Solar Pool Pump
Using a solar pool pump makes a lot of sense, and pools tend to get more use when the sun is shining.
DC Water-filled Motor Solar Pump
Submerging depth can reach 150 metersMore energy saving and environmental protection with water-filled motor
High Speed Deep Well Pump
The whole pump is small volume, saving the pump installation cost into the well.Maximum 6000RPM.
AC Water-filled Moter pump
Submerging depth can reach 200 metersNo mechanical seal is used, so it can avoid water leakage
Solar Aerator Pumps
Reduce reliance on the grid, reduce carbon emissions and reduce operating costs to ensure your production is on target.
Water Pump Controller Technology
MPPT technology maximizes the power utilization of photovoltaic modules and continues to improve.
Pump Motor Technology
Water-filled motors ensure reliability and avoid oil contamination. Brushless DC motor is specially designed for solar power.

WATER-COOLED SOLAR PUMP WITH EXTERNAL CONTROLLER

Well Depth(m): 1): Pumping water from boreholes: please provide the vertical height from the static water level to the top of the well casing;
2): Pumping water from a river: please fill in 0 for this value.

Horizontal Distance(m): 1): Distance from the water source (top of the well casing or other water source like a river) to desired destination.

Tank Height(m): 1): Vertical height from water source (top of the well casing or other water source like a river) to desired destination(such as water tank)

Flow(m³/h): 1): The amount of water required per hour
