Excellent efficient Francis spiral turbine with regulated guide vanes offers excellent flowregulation from ****0% of rated flow and has emergency closure secured by weight(turbine and valve). Maintenance free design of moving parts and stainless material (guidevanes, regulation system) ensures minimal maintenance and operating work and costsduring working period. Francis spiral turbine with runner mounted on generator shaft ismost efficient design of a turbine. Runner is usualy mounted directly, taht is why turbine has nobearing friction loss. Custom made stainless steel runner is corrosin resistant and goodwear resistant. Special sealing system with water suction ensures no leakage out ofturbine. Turbine design ensures easy cleaning of turbine runner and spiral in case of dirt. Turbine design and good materials ensures long working period of few decades.
