WARNING!
Risk of injury and poisoning due to hazardous or hot pumped
media!
– Use personal protective equipment during all work on the pump.
– Allow the pump to cool prior to work, if possible.
– Ensure that the pump is pressure-free.
– Empty the pump, flush if necessary and safely contain pumped
media and dispose of in an environmentally friendly manner.
– When working on the system always monitor for gas leaks
using an appropriate gas detection device (fixed installation or
mobile gas detection device).
– Do not work on the system alone or without regularly reporting
back.
– For applications with natural radioactivity:
– Wear breathing protection, avoid inhaling dust and absorp-
tion of solids.
– Decontaminate or dispose of clothing after work.
Mechanical seals have a function-related leak (
instructions).
Mechanical seals are subject to natural wear, which largely depends
on the respective conditions of use. It is therefore not possible to
provide general information regarding the service life.
Maintenance intervals are shorter with more severe operating condi-
tions (e.g. frequent switching on/off, high temperatures, low vis-
cosity, aggressive environmental and process conditions).
