Main characteristics
Great for constant flow
The highest efficiency at constant flow.
Stainless steel

Simplicity in design
Runner is located directly on generator shaft (alternatively, a coupling and dedicated bearings are used).
Bypass structure
for closed piping systems.
Spiral casing
Welded in segments.
Horizontal or vertical axis
to accommodate all sites requiring a Francis turbine.
