WATEC-Hydro – KDR Kaplan turbine

Proven technology, rock-solid implementation: our basic KDR model with belt drive.


The KDR is our classic Kaplan turbine. It has a vertical shaft, is double-regulated, with belt drive. The generator is driven by a high-performance flat belt with a leather friction layer. On-site gluing of the high-performance flat belt is not necessary since it can be mounted in a boundless state without dismantling the turbine traverse system. This proven turbine concept is significantly cheaper than our direct-drive models, which offer approximately 5% more efficiency in annual production.
