The Turbex
is the modern version of the traditional windmill where the well proven helical screw pump is driven with wind power. The concept was a major break through in windmill technology and is even today a leader in its field globally. The machines were developed in South Africa for the African conditions, and after 30 years of experience and more than 3000 machines being successfully installe
d, the Turbex is definitely the leader in South Africa as far as pumping performance and water pumping cost is concerned. There is no windmill in South Africa, and any other place in the world that we know of, that can match the Turbex’s performance under the same conditions. The Turbex pumps more water for smaller installations which dramatically reduces the pumping cost. It pumps more water from deeper bore holes, which very few, if any other windmill can equal. The machine also pumps water over great distances which is not achievable with any reciprocating (up-and-down ) windmill. The Turbex is also used very successfully for irrigation purposes. Under certain conditions the Turbex exceeds pumping rates of 200 000 liters per day. THE PRODUCT
The Turbex uses a modern type pump called a helical rotary pump that is driven by the wind. This pump rotates whilst the traditional pump operates with a reciprocating (up-and-down) motion. The helical rotary pumps are the leading bore hole pump type in South Africa today. Advantages of Rotary Windmills Other wind powered systems find it difficult to match the Turbex' performance under the same conditions. MORE WATER The Tubex pumps more water for smaller installations which dramatically reduces the pumping costs. Take a typical example. A Turbex Wind Turbine with a 4.6 diameter wheel, operating in a 20 km/h wind and installed on a borehole 30 m (100ft) deep, will deliver 30 000 liters of water per day. That is almost 11 000 000 liters per year! DEEPER WATER Getting water at great depths was uneconomical in the past. The Tubex has now made it a feasible reality. The manufacturers of the rotary borehole pumps certify that these pumps can operate at depths of up to 200 - 240 m. Very few, if any, other wind driven units can reach these depths. PUMP WATER FOR KILOMETERS You can install the Turbex at the water source and pump it to wherever you need it. Even the smallest Turbex will maintain a pumping rate of 1000 liters/h over a distance of 15 km in a typical wind speed of 20 km/h using a 40 mm pipeline. IRRIGATION If you have access to a dam, channel or river you can use the Turbex for irrigation purposes. A Turbex Wind Turbine with a 5.5 diameter wheel, operating in a 20km/h wind pumping from a river or dam will deliver 12 000 liters/h. In strong winds this can go up to more than 40 000 liters/h. RELIABILITY The Turbex is as reliable as it is effective. The following features make these machines especially reliable:
The Turbex automatically feathers out of strong winds to prevent over speeding and can absorb gusts of wind without damage. The wheel is exceptionally strong and can withstand wind velocities of up to 150 km/h. The unique tower is designed for strength
The machine tracks the wind's changing direction. The Turbex can withstand harsh weather conditions such as heat waves, storm winds, snow, rain, icing, and corrosion for many years. Long life bearings ensure low maintenance
