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.
Steam power turbine PC 750 (API 611)
A modern single-stage turbine whose design meets all the requirements of API 611, e.g. steam inlet and outlet on the bottom half of the casing, dynamically rigid rotor (critical speed is significantly higher than the maximum operating and trip speeds). Bearing lubrication with overpressure oil supplied by the oil pump. The turbine is also available with a gearbox or without for direct drive.
It is on a common frame with a gearbox and a powered machine.
The turbine developed in the years of 2014-2016 is characterized by its high efficiency and therefore low specific steam consumption per 1kW of clutch power, as well as the option of operation with very high outlet steam pressure.

Multistage turbines for propulsion
Multistage axial condensing and back pressure turbines are also used as drive turbines. Our condensing turbines are also used to drive a gear compressor in Poland or directly drive a compressor in Hungary.
