10.7. Repair, servicing and interventions into
explosion-protected submersible motors
For repairs or interventions, first observe the safety de-
terminations, especially those relevant for ex-protective
aspects as described above.
Who is permitted to repair ex-equipment?
Caution! Repair measures must only be carried out
by the works customer service or persons delegated
by us or workshops with an officially recognized „Au-
thorized person"
Gap dimensions
Caution! In the case of external repairs it is neces-
sary to obtain information on the model type approval
and the particular conditions, e.g. gap dimensions.
Gap surfaces must not be worked on!
Servicing intervals of ball bearings
Caution! Besides the operating instructions for servi-
cing intervals for non-explosion-protected submer-
sible motor pumps, the ball beatings must be repla-
ced at the latest after 25,000 hours. Depending on the
type of operation of the submersible motor pumps,
this time can be achieved in approximately 4 years.
Spare parts
Caution! In the purchasing of spare parts use only
the original spares mentioned in the appended parts
list. Especially the seals and cables are created in
part from temperature and aging-resistant materials.
Cable connection after repair
Caution! The cables are to be connected according
to the wiring diagram for the explosion-protected
submersible motor pumps to the ex-terminal board or
to the flameproof conductor bushing.
