Kaplan Turbines

Maximum Output and Control in Higher Head Conditions

CHC manufactures a range of conventional Kaplan turbines from 500mm to 3200mm. CHC's Kaplan design uses a servomechanism for the runner blade actuation downstream of the cross-head instead of upstream. This design is preferred as it allows easier access to the servomotor seals and importantly eliminates displacement effects within the hub, significantly reducing seal wear and the possibility for foreign matter entrainment in the hub assembly.
