Image : Geared Turbo Drive with Hydraulic Coupling

This step-up gear with built-in fluid coupling is a compound gearbox with a compact variable-speed fluid coupling built in on the rear side of the step-up gear.
We created this superior product from the high-speed gear technology and fluid coupling technology we built up on gas turbine and steam turbine generators, turbo compressors and similar devices.
In particular, when used with the boiler water supply pumps of thermal power stations, its power consumption is far lower than the conventional type, which keeps the pump speed constant and uses a valve to control output flow.
