How to choose a solar pump:
Confirm you technical requiremt
How deep is your well(bore hole)?
How far is the distance between tank and well?
What’s you requirement about the flow(L/H)?
Choose solar pumps according to your needs
Calculate”Actual Pump Head”and find the proper pump with the right head.
Then you can choose the pump you want according to different folw and prices.
