* Iron Man 702 water pumping windmills are back geared for low wind speed operation and ability to pump from greater depths and are preferred over direct drive windmills. There are applications where a direct drive windmill can be used to advantage, such as pumping a high volume of water up small pumping elevation with strong average wind speeds. We are happy to provide quality direct drive windmills for such applications. Please contact us for further information.
