DECOMMISSIONING/DISPOSAL

WARNING: rotating parts!
The rotating parts can crush and sever limbs. Do not
reach into the hydraulics or touch the rotating parts
when the machine is in operation. Switch off the
pump and allow the rotating parts to come to a
standstill prior to maintenance and repair work!
The following must be checked at regular intervals:
• Operating voltage (permissible deviation +/- 5 % of the rated voltage)
• Frequency (permissible deviation +/- 2 % of the rated frequency)
• Current consumption (permissible deviation between phases is a maximum of 5 %)
• Switching frequency and switching pauses (see technical data)
• Minimum water submersion
• Quiet and low-vibration running
• Gate valves in the pressure pipe must be open.
8. Decommissioning/Disposal
All work must be carried out with the greatest care.
Proper protective clothing is to be worn.
When carrying out work in wells and/or tanks, the respective local protection measures
must be observed in all cases. A second person must be present for safety reasons.
Auxiliary lifting devices in technically perfect condition and officially certified lifting
gear must be used to lift and lower the pump.
RISK of fatal injury due to malfunction!
Lifting gear and lifting devices must be in a perfect
technical condition. Work may only commence if
the lifting device has been checked and found to be
in perfect working order. If it is not inspected, fatal
injuries may result!

Temporary shutdown

For this type of shutdown, the pump remains installed and is not cut off from the elec-
tricity supply. In the event of temporary shutdown the pump must remain completely
immersed so that it is protected from frost and ice. Ensure that the temperature of the
fluid and in the operating space does not fall below +3 °C.
This ensures that the pump is always ready for operation. For extended downtime, a re-
gular (monthly to quarterly) 5 minute test run should be carried out.
