Operating instructions 10/2017
WARNING
Risk of scalding
Risk of serious injury through escaping hot operating fluid, when it is being changed.
Wear suitable protective gloves, protective glasses and protective clothing.
Allow the operating fluid to cool down.
The behaviour and the efficiency of the FLUDEX coupling are decisively affected by the quantity of
operating fluid put in. As the filling increases, so does the transmitting capacity of the coupling, and the
motor load during starting and the maximum overload torque on the coupling rises. Operating slip
decreases with unchanmged load.
WARNING
Risk of serious injury through flying fragments
Risk of serious injury through flying fragments and/or risk of damage to the coupling.
The filling quantity is defined by the works in relation to the order, if the drive details are available.
Otherwise the filling quantity is selected from the table in the operating instructions. FLUDEX couplings
must not be filled up to more than 80 to 85 % of the total volume. Higher filling quantites cause a sharp
rise in pressure in the coupling, which may cause the coupling to burst. The instructions for use enclosed
by the operating fluid manufacturer must be observed. Only the filling openings prescribed must be used
for filling.
The operation fluid should be filled in through a fine filter element (mesh width ≤ 30 μm) on the filler
plug (153), see figure 11. Only these filling holes are provided with a filling channel, which offers protection
against accidental overfilling. To better ventilate the inner chamber, the screw plug / fusible safety
plug (163) inserted in the outer flange, or the second fusible safety plug (103), should be unscrewed. It is
set at an appropriate angle so that, in the event of imminent overfilling, the excess can escape there.
