ATEX Approved PARA-FLEX Couplings
These instructions do not cover all details or variations in
equipment nor provide every possible contingency or hazard
to be met in connection with installation, operation, and
maintenance. Should further information be desired, or should
particular problems arise which are not covered in this manual,
the matter should be referred to your local ABB representative.
DODGE Elastomeric couplings are manufactured under the
guidelines of the ATEX directive 2014/34/EU.
DODGE Elastomeric couplings are suitable for ATEX category
2 and M2, Group II and I for gas and dust environments
and are also suitable for ATEX category 3 for all gas or dust
environments with ignition temperatures higher than T5 = 100°
C.
A sticker indicating ATEX certication will be attached to the
product or on the box containing the product and will be similar
to the following:

Figure 9 - ATEX Certification
WARNING: These couplings are designed to operate with surface
temperatures below 100°C when properly installed and selected.
Excessive temperatures greater than 80°C is a result of an
abnormal operating condition caused by:
1. Improper installation - refer to installation manual for
proper procedures
2. Excessive misalignment - re-align coupling / shafts
3. Failure of the coupling element - replace elastomeric
4. Excessive speed - re-evaluate application and selection
5. Excessive vibration - determine source, re-evaluate
application
If applied in a Division 1 or Zone 1 environment, the excessive
temperature may cause ignition of hazardous materials.
