Pump-turbines

In 1937 we developed the first large pump-turbine, which operated both as a turbine for energy generation and, in the reverse direction, as a pump.

Today, nearly 200 Voith pump-turbines have been installed worldwide with a combined output of over 25 000 MW. With a wide range of specific speeds, pump-turbines can be installed at sites with heads up to 700 m, and with unit capacities ranging from less than 10 to 500 MW.

The company’s state of the art technological level is being constantly worked on and includes latest developments on variable-speed technology and wide head range applications. These machines have proven extremely reliable in practical operation. In some cases this experience covers many decades. It makes no difference whether demand is for a reversible pump-turbine or an optimally designed combination of turbine and pump.
