Product Description

Turgo Turbine is a kind of impulse turbine suitable for head from 20 to 300 meters. An angle of 22.5o is formed between the center line of the nozzle and the rotational plane of runner. Turgo type is characterized not only by higher flow, even efficiency curve, but also by simple construction, reliable operation, easy maintenance and low cost.
