Start with the duty, then choose the pump.
These guides help you prepare the information needed for a useful model recommendation. They describe general selection principles—not model performance guarantees. For a purchase, request the current technical sheet and curve.
How to size a solar water pump
Start with the water you need to move, where it starts, and where it must arrive. Then compare a complete pump, controller and solar-array combination at the required duty point—not just a motor's HP label.

A series name narrows the layout. The operating duty point and current model curve determine whether a particular pump can do the job efficiently and reliably.

Oil, sludge and wastewater cannot be selected from a clean-water duty point alone. Describe the liquid and process before choosing between screw, diaphragm, oil-transfer and wastewater ranges.
