Dutch F8 Windmill Water Pump

This windmill is designed strictly for water pumping. The F8 comes in 3 tower sizes: 10 foot, 20 foot, and 30 foot to suit your windmill location. The self furling tail turns the windmill head out of the wind during higher than normal wind speeds. Also the only maintenance to this windmill is 1 grease nipple that needs to be greased once per year.
