10.1.3 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 "Cleaning".
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.
Restarting
Re-install the pump according to the procedure described in chapter 3.3 "Installing and
Connecting" .
Important:
!
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 9.2
must be carried out. For the new re-start the points listed in section 7.1 "Initial Start-up"
must also be observed.
Particularities of the mechanical seal:
Information:
i
Prior to an initial start-up and after longer periods of standstill or after a new
mechanical seal is installed it is important to check that the pump runs freely.
The sliding ring and its counterpart ring can stick together very firmly due to adhesive
forces. The force of the driving spring is then not enough to break the sliding ring away.
In this case the shaft runs in the static seals and the driving spring, which leads to damage.
Remove the blower cover and turn the blower wheel in the direction of the arrow. If there
is resistance and the blower wheel feathers back then the mechanical seal has to be
removed and the sliding ring and its counterpart ring must be carefully separated. Under
no circumstances should the shaft be turned by force.
