Pelton Turbines

High-pressure impulse turbine for up to 25 MW


Pelton: powerful turbines for pure hydropower

The Pelton turbine is also known as an impulse turbine. Due to its method of operation, this water turbine is ideally suited for hydropower plants with very high heads (over 30 and up to 1,500 m) and comparatively low water volumes. The turbines are manufactured at the Geppert plant in Hall, Tirol, using world-leading engineering skills.


High-tech hydropower up to 30 MW

The Pelton turbine is designed with internally and externally regulated nozzle assemblies, each consisting of one to six nozzles. Depending on the number of nozzles, single- to three-nozzle machines are built with a horizontal design, while two- to six-nozzle machines are built with a vertical design. Each individual nozzle is regulated separately, which guarantees an optimum efficiency curve. Geppert offers a special extra feature for turbines with externally regulated nozzles: a scavenging stroke for easy unblocking of obstructions such as accumulated leaves or other foreign matter in the works water – even when the plant is in operation. This means that the machine does not have to be shut down or opened for cleaning.


Water is life – and Geppert lives for water (power)

Geppert Hydropower is passionate about generating sustainable and clean energy from hydropower, and this fascination with emission-free electricity generated from hydropower has for many decades been the driving force behind our active efforts to maintain a healthy environment. Based in Austria, a country famous for its mountains and its water, Geppert also offers water turbines in a design suitable for drinking water. If you and your grandchildren want to enjoy fresh, pure water both now and in the years to come, water which was used to generate renewable energy on its way to your home, you can – it’s up to you.
