Admissible Temperatures
Admissible temperatures for transported liquid and pump
surface, depending on the ATEX temperature class.

Maintenance and Service

To reduce the occurrence of problems with the pump, the preventive maintenance
schedule must be followed, otherwise a safe operation in a hazardous location is
not guaranteed.
This is particularly important for wearing parts like mechanical seals, O-rings and
bearings. A regular visual inspection of static seals is mandatory.
Personnel should be sufficiently qualified and thoroughly familiar with the operation
of the pump, before starting any maintenance procedure. The same holds for
inspection and cleaning in the case of a possible dismantling and reassembling of
the pump. During this kind of work, an explosive atmosphere should not be
present.
Inspection and Maintenance Intervals:
Daily:
Oil level in the pump gearing, visual leakage control
Monthly / after 720 hours:
Oil level (viewing lass at the side of the gear case)
Yearly:
During the exchange of the mechanical seal, inspect and, if necessary, replace the
rolling bearing. O-rings and rotary seals sometimes have to be exchanged as well.
