Kaplan Turbines

Low-pressure turbine for up to 7 MW


Top performance with low pressure
Named after the world-famous Austrian inventor Victor Kaplan, this is a low-pressure turbine offering extremely high efficiency. Due to its method of operation, this water turbine is ideally suited for power plants with large quantities of water.


Maximum hydropower
In order for the rotational energy of the works water to be reduced to a minimum in the draft tube, an ideal relationship is established between the angles of inflow of the guide vanes and rotor blades over the entire impingement area for the water flow. For individual adaptation to the respective power plant, Geppert offers different options for these systems: as open-flume, bulb, Z or S turbines. They are available in a horizontal or vertical design with three to six blades – depending on which approach will ensure optimum utilization of the hydropower. A special feature of the Kaplan turbine is that the submersible generator and the impeller are mounted on a common shaft. Directly coupled permanent-magnet or asynchronous generators are used,
allowing a compact design and eliminating the need for a gearbox and belt drive.


High tech – high quality
From Geppert’s base in the heart of the Austrian mountains, the company is proud to develop and manufacture its turbines and plants to the highest quality standards using Austrian engineering skills. The advanced technology used in Geppert’s turbines and small power plants ensures they are a secure long-term and future-oriented investment. From research, design and development to production, erection and commissioning, as a full-service provider Geppert Hydropower is a byword for safety and trust.
