7 Maintenance
Trained service technicians are available for ¿ tting and
repair work. Submit evidence of conveyed medium on
request (DIN safety data sheet or safety certi
¿ cate).
7.1 Inspections
The inspection intervals depend on the operational strain
on the pump.
DANGER
Risk of injury due to running pump!
Do not touch the pump when it is running.
Do not carry out any work on the pump when it is running.
WARNING
Risk of injury and poisoning due to hazardous pumped
liquids!
Use protective equipment for any work on the pump.
1. Check at appropriate intervals:
– Adherence to the minimum À ow rate
– Normal operating conditions unchanged
– Filling level of the container
2. For trouble-free operation, always ensure the following:
– No leaks
– No cavitation
– Free and clean ¿ lters
– No unusual running noises or vibrations
– No inadmissible leaks on the shaft seal
7.2 Servicing
Operating life of antifriction bearings in operation are within
permissible range: >2 years.
Intermittent operation, high temperatures, low viscosities
and aggressive ambient and process conditions reduce the
service life of antifriction bearings.
Plain bearings are subject to natural wear and tear which
is heavily dependent on the respective operating condi-
tions. It is therefore not possible to make general state-
ments about the operating life.
DANGER
Risk of injury due to running pump!
Do not touch the pump when it is running.
Do not carry out any work on the pump when it is running.
Before all installation and maintenance work, disconnect
the motor from the mains and secure it against being
switched back on again.
DANGER
Risk of electrocution!
All electrical work must be carried out only by quali ¿ ed elec-
tricians.
Before all work on the electrical system, disconnect the
motor from the mains and secure against being switched
back on again.
WARNING
Risk of injury and poisoning due to hazardous or hot À uid!
Use protective equipment for any work on the pump.
Allow the pump to cool down completely before commenc-
ing any work.
Make sure the pump is depressurized.
Empty the pump, safely collect the pumped liquid and dam-
age it in accordance with environmental rules and require-
ments.
7.2.1 Maintenance in accordance with main-
tenance schedule
Perform maintenance work in accordance with the mainte-
nance schedule
( ĺ 9.3 Maintenance schedule, Page 32).
7.2.2 Cleaning the pump
NOTE
High water pressure or spray water can damage bearings!
Do not clean bearing areas with a water or steam jet.
