Maintenance / Repair
General Instructions
The operator must ensure that all
maintenance, service and repair work on
the pump is carried out exclusively by
authorised and specially trained persons. It
must be established beyond doubt that the
person has studied the operator’s manual
in detail.
We recommend the creation of and
adherence to a maintenance schedule.
That will enable you to avoid expensive
repairs and have a reliable and trouble-free
pump operation.
Only original spare parts must be used for
repairs.
If work has to be carried out on the
motor
the instructions in the manual from the
relevant motor manufacturer must be
observed.
5.1
Maintenance / Service
Use the following information to create a
maintenance schedule. These are
recommendations of minimum
requirements that must be adjusted to local
conditions of use of the pump and may
need amending accordingly.
5.1.1
Checks
Continuous checks:
•
Pump delivery data (pressure, amount)
•
Power take-up
Daily checks:
•
Pump running is quiet and vibration free
•
Bearing temperature (see section 4.3.1)
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 or
sticks. If this happens, smooth operation
must be restored before starting up. See
section 6.1.3 "Restarting after Periods of
Storage".
Monthly checks:
•
Wear on the coupling (elastic compo-
nent)
•
Screws are tight
5.1.2
Lubrication and change of
lubricant
Pumps in their standard models only have
bearings in the drive motor. In the models
with IEC motor and intermediate stub the
bearings in the intermediate stub are filled
with a grease that cannot be replenished.
This grease lasts for the working life of the
unit and cannot be replenished. Defective
bearings must be replaced.
Bearings in larger motors must be
relubricated on a regular basis. See also
the "Operator's Manual for Pump Drives" in
section 6.2 "Motor Bearings"
.
Mortal danger!
In order to prevent electric
shocks, work on the terminal
box and the machine controller
must never be carried out
before the electrical
connections have been
isolated or disconnected.
Attention! Danger of injury!
Mortal Danger!
The pump must be
safeguarded against
unintentional switching on (be
disconnected) if checking or
maintenance work is to be
undertaken.
