Francis turbine

Design for drinking water systems with long pipes and back pressure

Minimum change in water flow through the turbine when transferring to the runaway speed = minimum hydraulic impacts
For head from 50 to 150m and nominal flow capacity from 120 to 430l/s
Type series 3.8/4.8 – F 90
Guide vanes and runner are made of stainless steel
Electro-mechanical or hydraulic drive of the control with the option of full closing
Special coating for humid environments (construction design for drinking water)
Special bypass structure for closed piping systems
High efficiency at constant flow (50–100% of installed flow)
The runner is located directly on the generator shaft (alternatively with a clutch and own bearings of the turbine shaft)
Spiral casing, welded in segments
Possible horizontal or vertical location of the shaft
