Kaplan turbines

Solutions for low heads

The axial turbines are designed for projects with low and very low heads with a strong flow variation.

VAPTECH offers mainly the classic vertical shaft Kaplan turbine with 3 to 6 runner blades and with double regulation. For runner diameters up to 1400 mm we use a steel spiral casing and for bigger runner diameters we recommend a concrete spiral casing.

Our solution and advice is for a direct coupling of the generator shaft to the runner without the use of speed increaser and therefore without loss of efficiency.

The runner is manufactured from high quality stainless steel castings with CNC machining. The blades surface is controlled to assure the integrity of the physical part with the computer model.
