Appendix
6.1
Shutdown / Storage /
Conservation
Every pump leaves the factory carefully
assembled. If initial operation is predicted
to be a long time after delivery we
recommend the following measures for
storage of the centrifugal pump.
6.1.1
Storage of New Pumps
When requested, new pumps receive a
conservation protection corresponding to
the storage time stated by the purchaser. If
this period of time is considerably
exceeded the condition of the pump must
be checked and, if required, re-conserved.
6.1.2
Longer Periods of Shutdown
>3 months
1. Pump remains installed
To ensure that the pump is always ready for
operation and to prevent the formation of
deposits inside the pump and in its
immediate vicinity, the pump aggregate
should be run for a short time (approx. 15
minutes) monthly or quarterly during longer
periods of inactivity. Prerequisite for this is
that sufficient fluid is supplied to the pump.
2. Pump is removed and stored
To remove the pump proceed as outlined in
chapter 5.
Prior to storing the pump it must be
thoroughly cleaned and conserved.
Conservation must be done both internally
and externally.
6.1.3
Restarting after Periods of
Storage
De-conservation
Before the stored pump is re-installed the
conservation agent (covering or filling)
must be removed. Proceed as described in
chapter 3.2.2.
Restarting
Re-install the pump according to the
procedure described in chapter 3.3.
Immediately after completing the above
work, all safety and protective measures
must be properly installed and checked that
they function.
Before the pump is re-started the checks
and maintenance measures stated in
chapter 5.1 must be carried out. For the
new re-start the points listed in section 4.1
“Initial Start-up” must also be observed.
6.2
Disposal
If you want to take the pump completely out
of service and never re-use it then please
observe the local regulations for the
disposal of industrial waste.
Warning!
After long periods of storage
under conservation conditions
check the shape stability and
elasticity of the Elastomers (O-
rings and mechanical seals).
Brittle rings must be replaced.
Elastomers made of EPDM
should be replaced in any
event.
Important: Mortal danger /
Poison
Pumps that have delivered
poisonous, caustic or other
chemical substances which are
hazardous to the health of
people and animals must be
thoroughly cleaned and / or
decontaminated prior to being
disposed of.
The cleaning agents and rests
of the delivery medium must
also be handled in accordance
with legal requirements.
