Download Catalog

Invented in 1912 by Victor Kaplan in Brno, the second largest Czech city, the Kaplan turbine gained widespread popularity due to its high efficiency over a wide range of site conditions. In the 100 years since its creation, a variety of turbine configurations have been developed. The Kaplan turbine automatically adjusts its runner blades and wicket gates to suit changing water conditions. This unique adaptability enables consistently high efficiency over a range of flow and head conditions. Mavel’s Kaplan turbines are optimal for run-of-river projects with low heads from 1.5 to 35 meters (5 to 115 feet) Mavel produces five different configurations of the Kaplan turbine. Mavel’s Kaplan turbines have three to six runner blades and can be single or double regulated. Mavel has over 260 Kaplan turbines installed at sites around the world. The BULB configuration is best suited for low head and moderate flow and can be attached to the generator via either belt drive or a gearbox. Kaplan Bulb runner diameters are 1050 mm to 2500 mm. Power output is 100 kW to 3 MW.
