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.
