This is physically possible but is NOT SUPPORTED by Simple Pump Co. There are pumps designed specifically for this purpose; the Simple Pump is not one. Such an installation will void all warranty.

We cannot offer a warranty when the Simple Pump is being driven by a very powerful mechanical device of someone else’s construction. In addition, you have no power when the wind isn’t blowing. Not a great option when you want a secure, reliable water supply. The recommended and supported use of a windmill is to drive a generator that charges batteries to then power our motor.
