With more than 60 years and 13,000 references for the Power Generation and the Oil & Gas industries, Flender-Graffenstaden has been a leader in the field of high speed gears.
Flender-Graffenstaden high speed gear units are preferred by professionals in search of high power transmission with very low power losses.
With high precision manufacturing, control standards and the most modern technologies knowledge in the field of gearboxes, every single gear unit is tested in Flender-Graffenstaden facility to demonstrate satisfying operation while highly reliable instrumentation is installed to enable efficient monitoring on-site.
Turbo gear units
Driven by gas turbines, steam turbines or electrical motors, our single and double helical turbo parallel shaft gear units are preferred by professionals in search of high power transmission with very low power losses. To accommodate the constantly increasing transmitted powers, our R&D experts, manufacturing professionals, quality specialists and design engineers team provide qualified design and manufacturing processes, ensuring the production of more powerful but still reliable gear units even at very high powers and pitchline velocities. Enclosed in rigid welded steel or cast iron casings,
Flender-Graffenstaden gear units can be equipped with a lubricating oil pump or a turning device connected to the free shaft ends of the gear train, according to specific needs.
Integral gear units
For industries looking for high efficiency compression systems, Flender-Graffenstaden provides single or multiple meshing integral gear units using single helical and thrust collar designs. With impellers directly mounted to the gear casing, these products form an integral unit with the driven compressors and expanders (integrally geared compressor).
These multi-stage gear units can also incorporate other machines such as electric motors, steam, gas turbines, coolers and turboexpanders.
Using the latest knowledge in vibration analysis, journal and thrust bearing technology, sealing systems, finite element calculations for both shafts and casing and the know-how acquired over 60 years of gear manufacturing, Flender-Graffenstaden now provides integral gear units weighting over 50 tons and wheel diameters reaching 3 meters for process plants.
