These machines are all equipped with adjustable distributor blades carefully finished. The Francis runners (simples or doubles) are cast in one piece of stainless steel and carefully machined and finished.

The distributor blades bushes are self lubricated and made with non polluting materials.

In some cases Francis turbines compete with Pelton, because they tend to be more compact, than the multi injector Pelton and they can run at higher speeds.
