FLENDER Standard Couplings Fluid Couplings — FLUDEX Series © Siemens AG 2015 General information Selection of FLUDEX type Listed in the catalog are FLUDEX couplings with pulley, brake drum, brake disk and flexible N-EUPEX coupling. Further types, e.g. in combination with a torsionally rigid steel membrane coupling of the ARPEX series or a highly flexible cou- pling of the ELPEX or ELPEX-S series, are available. The maximum shaft misalignments permissible for an N-EUPEX add-on coupling are shown in catalog section 7. For greater shaft misalignments FLUDEX couplings can be combined with cardan shafts or other displacement couplings.
13 1) Enables change of flexible elements without moving the machines axially. 2) Enables the coupling to be fitted or dismounted without displacing the coupled machines. 13/10 Siemens MD 10.1 · 2015 Series Type Add-on coupling Characteristic feature FA - without delay chamber - impeller-driven - Starting torque: Tmax = 2.0 x Teff - Starting aid for standard motors and torsional vibration isolation FAO Without FAR Without FAD N-EUPEX D FAE N-EUPEX E FAM N-EUPEX M FADB N-EUPEX D FADS SB N-EUPEX D FADS HB N-EUPEX D FG - without delay chamber - Housing-driven - Starting torque:
