Custom Pelton turbines

Pelton turbines are impulse turbines, suited to high-head plants with relatively small flow rates. Instead of harnessing water pressure like reaction turbines, they convert all the energy into velocity through nozzles that strike the buckets of the runner.

Servoship manufactures custom Pelton turbines with power outputs of up to 3,000 kW and heads of between 80 and 500 metres. They are usually installed with a horizontal shaft and one or two nozzles, although we also build them with a vertical shaft for configurations with a larger number of nozzles.

The efficiency at the optimal point is above 90%, and it stays high across a very wide flow range: they accommodate variations between 105% and 20% of the nominal flow, which makes them ideal for high-mountain sites with highly seasonal flow.
