Maintenance / Repair
General Information
The operator must ensure that all inspection, maintenance and repair work on the pump is
performed only by authorised and specially trained personnel. The operator must ensure
that personnel is sufficiently informed through thorough study of the Operator's Manual.
We recommend creating and following a maintenance plan. This will help you to avoid
costly repairs and achieve problem-free and reliable operation of the pump.
Only original spare parts may be used for repairs. This applies especially to the mechanical
seal (GLRD).
When working on the
motor
, the manual of the relevant motor manufacturer and
instructions in it must be followed.
4.1
Maintenance / Inspection
The following information should be used to create a maintenance plan. It consists of
minimum recommendations that must be adjusted and if necessary supplemented as
required by local specific details of the actual installation site.
4.1.1
Checks
Continuous checks:
•
Pumping data for the pump (pressure, quantity)
•
Current consumption
Daily checks:
•
Pump running = quiet with no vibration
•
Storage temperature
•
Mechanical seal leakage
•
SKS (catchment chamber system) has no sealing pressure = Check fluid level
More frequent monitoring must be planned for liquids with properties that differ greatly from
those of water (which tend to stick or form accumulations, for example, or have a high gas
content).
Smooth operation of the shaft may be impaired for example by accumulations on the
mechanical seal or if the mechanical seal sticks. If this happens, smooth operation must
be restored before starting up. See section 5.1.3 "Restarting after Periods of storage".
Danger of death!
Normally work on terminal boxes and on machine control must only be
performed with the electrical connections unclamped or the power turned off to
avoid electrical shocks.
Danger of injury and death!
During checks and maintenance work, secure the pump against being turned
on unintentionally (turn off the power).
