Possible faults

Faults

Possible causes

Remedy

Sudden changes in the noise
level and/or sudden vibrations.

Change in alignment.

Flexible elements (12) worn.

Stop the installation.

Rectify any cause of the changes in
alignment (e.g. by fastening loose
foundation bolts).

Check and, if necessary, adjust the
alignment; refer to section 6.

Check wear, procedure as described
in section 10.

Stop the installation.

Demount coupling and remove remains
of flexible elements (12).

Check and replace damaged coupling
parts.

Flexible elements (12) must be
replaced in sets.
Only use similar N­EUPEX flexible
elements (12).

Fitting of coupling according to section
6 and section 7.

No torque transmission.

The fusible safety plugs have
fused through overheating or
locking and the fluid is escaping
from the coupling.

Stop the installation.

Rectify the cause of the overheating or
locking.

Fit new fusible safety plugs with new
sealing rings

Refill the coupling as described in
section 7.

If the torque is being transmitted with worn N­EUPEX flexible elements (12) and metal
parts are consequently in contact, proper operation within the meaning of the
explosion protection requirements or Directive 2014/34/EU can no longer be
guaranteed.

Measurement and assessment of the wear condition of the N­EUPEX flexible
elements (12) in accordance with section 10.

9.3

Incorrect use

Experience has shown that the following faults can result in incorrect use of the FLUDEX coupling. In
addition to observing the other instructions in this manual, care must therefore be taken to avoid these
faults. Directive 2014/34/EU requires the manufacturer and user to exercise especial care.

Failure to observe these instructions may result in breakage of the coupling.
Danger from flying fragments.
Through incorrect use the coupling may become an explosion hazard.

Incorrect use of the FLUDEX coupling can result in damage to the coupling. Coupling
damage may result in stoppage of the drive and the entire system.
