Gas turbine unit GTU-4PG
GTU-4PG is developed on the basis of the gas generator of the most reliable D-30 engine in the history of the domestic aviation industry, created for long-haul passenger aircraft such as Tu-134.
Gas turbine units with a nominal power of 4 MW are used as part of new generation gas pumping units at underground gas storage stations, as well as as a mechanical drive for pumps, compressors, etc.
The M-45PHG high-speed intensifier included in the GTU-4PG allows optimizing the characteristics and increasing the economic performance of the gas pumping unit.
Serially produced since 2005.
Operator – PJSC Gazprom.
