How to choose pump？
Calculation of solar water pump head
1）L:Horizontal distance from solar water pump to water tank
2）H:Vertical distance from solar water pump to water tank
3）Total head = H+L*10%
Calculation of solar water pump Flow
1）Time: 5 hours (estimated working hours of solar water pump)
2）Daily water consumption: daily water consumption of water pump (m³)
3）Actual flow: daily water consumption/time(m³/h)
Pls select the right solar water pump below yourself, or pls inform us below information then we can select the right pump for you.
1. Where will the pump be used?
2. How much water discharge ( liters or gallon or m3) required per day or per hour?
3. Do you need a submersible pump or surface pump?
4. If you want to pump the water from borehole(deep well), the depth of borehole?
5. The pipe distance from the top of borehole or river to destination tank? Is the distance slope or horizontal?
6. The height of tank?
