Simple single shaft single stage turbines

They are designed to drive pumps, turbocompressors, fans, mills and crushers, or can be used to drive an electric generator.

The turbine is connected to the powered machine directly, i.e. without a gearbox. A gearbox is used at low speeds of the powered machine and when higher efficiency is required. They are equipped with one turbine stage located between the shaft bearings and two carbon ring seals. The turbine stage is implemented with partial admission of the impeller in two basic modifications – axial impulse stage and Curtis stage. The turbines are designed for long-lasting operation as well as temporary operation with very fast start-ups from hot standby and full power load in a matter of seconds.
