© Siemens AG 2015 FLENDER Standard Couplings Fluid Couplings — FLUDEX Series General information Selection of FLUDEX size The FLUDEX size is determined by the output to be transmitted in comparison with the rated outputs listed in the following ta- bles. No application factors or additional safety factors need be taken into consideration. The rated outputs stated in the tables normally require the maximum permissible filling (80 % to 85 %) of the coupling and because of operating slip, lead to the cou- pling heating up by approx. 50 °C relative to the ambient (cool- ing air) temperature. With lower outputs, coupling heating will be proportionately lower.
If for continuous operation of the coupling an absolute temperature (ambient temperature + coupling heat- ing) of > 85 °C is expected, the coupling must be fitted with FPM seals and 160 °C fusible safety plugs. FA series FG, FV and FN series The specified coupling weights of the following selection tables are effective for maximum bores without oil filling. 13 1) D = double-flow variant on request.
