Pelton turbines
These impulse turbine are characterized their particular runner, that exhibit numerous double tea-spoon shaped buckets: the water jet coming from a regulating nozzle is received by the rotating buckets, split in two halves, deflected for almost 180°, and then leaves the runner with almost no remaining energy. These turbine is widely used with head from […]
Tubolar turbines
With a very similar working principle to Kaplan units, these turbines have an horizontal shaft. This arrangement is optimal when paired with a penstock, and usually save lot of excavation volumes compared to a Kaplan unit. Likewise Kaplan units, they well fit with low head (from 2 to 16 meters) and relatively high flow situations, […]
Francis turbines
Characterized by their shell-shaped inlet conduit and a very particular runner, these turbines well fit heads from 20 to 200 meters and performing very high design point efficiencies (up to 94%). Each turbine should be calculated accordingly to the site characteristics (head and maximum flow), looking for the optimal combination of rotation speed and overall […]
Kaplan turbines
These vertical axis units well fit with low head, from 2 to 30 meters, and relatively high flow situations, showing a very wide high efficiency field thanks to their double regulated mechanisms: accordingly to the available flow, the distributor and the runner blades (from 3 to 5) take a position following a collimation curve, allow […]
