5.4 Seals and Radial Shaft Sealing Rings
For safety reasons, sealing elements and radial shaft seals
must be replaced at least in course of every maintenance
work, repair or replacement of parts, which requires that seal-
ing elements are opened, remove or otherwise manipulated.
The equipotential bonding must be inspected in conjunction
with every maintenance job and shall be in good operating
order after the maintenance job is completed. The measures
must not lead to interconnections between explosion protec-
tion zones.
The radial shaft seals must be in perfect condition; this must
be checked during all maintenance work.
5.5 Micro-fi lters
The degree of clogging of the fi lter mats should be checked
at regular intervals, depending on the ambient conditions /
conditions of use. This means that the user is responsible for
ensuring that the fi lters are permeable.
5.6 ATEX Impeller
The balancing as well as the lateral and radial travel of the
impeller may not be impaired as a consequence of mainte-
nance/service, repair or replacement of parts.
The impeller must be replaced at the latest when clearly de-
tectable vibration occurs, or when mechanical wear or dam-
age is visible.
Use suitable pullers when extracting the impeller. Groves
and fi xing threads are provided on the impeller hub, allow-
ing application of such tools. Install the impeller on the shaft
without impact or jerks.
5.7 ATEX Motors
ATEX motors can only be replaced as complete units. As
required by EN ISO 60079, repair of ATEX motors is exclu-
sively performed by the manufacturer of the motor.
Upon replacement of the motor, ensure exact axial alignment
of all parts connected to or coming in contact with the motor
shaft. Also see 5.6.
5.8 Cleaning
Cleaning or maintenance must not damage or alter the ap-
pliance and its component parts to the detriment of health
and safety protection, and must not, for instance, affect the
balancing of the impeller.
No agents / tools are to be used for cleaning that may lead to
electrostatic charge build-up or may give rise to other risks.
5.9 Repair and Replacement of Parts of Elektror ATEX

sponding legal requirements and regulations which must be

As specifi ed by law, the user is responsible for safety and
health protection during operation as well as for trouble-free
operation.
According to the ATEX directive for explosion protection as
well as the regulations and standards based on it, require-
ments detailing admissible and inadmissible material com-
binations have been published. Inadmissible material com-
binations may render ineffective any constructive measures
aimed at achieving explosion protection. This may substan-
tially increase the explosion risk entailed in ATEX products.
Spare parts list of non-explosion-protected devices must not
be applied to ATEX appliances and are therefore void.
Recommendation: Use only original spare parts provided by
Elektror as this will enable low-risk replacement.
