Development of an all-metal windmill with 5 meter wheel diameter and 12 blades is described. Sound methods of mechanical and aerodynamic design are used, even though the windmill is simple enough to be fabricated in a small workshop using commonly available mild steel sections. The windmill is connected to a single acting reciprocating pump which can be inserted in a tubewell. Stroke of the pump as well as pump diameter can be varied to suit the site conditions as the water table and wind velocity vary. The designed windspeed is kept low at 14 KMPH so that the windmill is suitable for low wind regimes and the cut-in wind speed is as low as 6 KMPH. The overall efficiency of the wind pump is found to be about 12-15 percent. The cost of the wind pump together with all metallic 7 meter high tower is about US $1,200, with a life expectancy of 20 years. Few of the windmills are already working and cost of water pumping is comparable to diesel or electric pumping.
