1) The limit values specified for the temperature of the medium at
the pump inlet are determined for the most unfavourable case
(high speed, low flow, low heat capacity of the medium, ....).
Under favourable operating conditions the limit values specified
may be increased by up to 5 K after consultation with the
manufacturer.
In the case of motors with the type of protection
"increased safety", no or low temperature entries are
generally permitted for the motor shaft and motor
flange related to an ambient temperature of 40 °C.
In these cases the max. admissible medium
temperature is 20 K above the temperature which may
be introduced into the motor.
e.g.: Max. motor shaft temperature: 60°C
Max. motor flange temperature: 65°C
This results in a maximum medium temperature for
the pump of 80 °C (60 °C + 20 K)..
2.6.8 Maintenance
For safe and reliable operation, it must be
ensured with regular inspection intervals that
the unit is properly serviced and kept in a
perfect technical condition.
If auxiliary systems (e.g. external flushing, cooling,
heating) are installed, a check must be made to see
whether monitoring facilities are required to safeguard
their operation.
2.6.9 Electric peripheral equipment
Electric peripheral equipment, e.g. pressure,
temperature and flow sensors etc. must comply with
the prevailing safety requirements and explosion
protection provisions.
Regular checks of the motor bearings in
accordance with the operating manual of the
motor manufacturer. Observe ATEX notes.
3 Transport, storage and disposal
The pump or the unit must be transported
properly. It must be ensured that during
transport the pump/unit remains in the
horizontal position and does not slip out of the
transport suspension points.
The ring bolts of the pump and the motor must be
used to transport the entire unit, i.e. pump with
baseplate and motor. See Fig. 1.
The slinging ropes must not be attached to free shaft
ends.
Fig. 1
Directly after receipt of the goods, the
consignment must be checked for completeness
and any in-transit damage.
Damaged pumps must not be installed in the plant.
When unpacking magnetic drives as single
parts, the relevant notes in Section 7.5.2
must be observed.
Handle goods carefully to prevent damage.
Flange covers serve as protection during transport
and must not be removed.
If the unit is not installed immediately after delivery, it
must be put into proper storage.
The product should be stored in a dry and vibration-
free, well ventilated room at as constant a
temperature as possible.
Elastomers are to be protected against UV light.
In general, a storage period of 10 years should not be
exceeded. An admissible storage period of 4 years
applies to elastomers made of NBR.
If magnetic drives are stored as single parts,
the relevant notes in Section 7.5.2 are to be
observed.
In the case of prolonged storage conservation
agents on machined component surfaces and packing
with a desiccant may be necessary.
