4.4 Intermediary storage
Pumps can be provided with preservation agents on delivery. Their effective life amounts to between 6 -
12 months. With long intermediary storage or putting out of use the pumps must be treated inside with a
preservative. When present, connections for rinsing, circulation or cooling must also be closed. All not
painted parts and the rotating parts must be provided with a coat of preservative. The choice of
preservative depends on the materials and the application. The pumps must be stored covered and well
ventilated. Temperatures below freezing point and high air humidity must be avoided.
If the pump is not immediately to be taken into use, one must once a week
manually turn the pump shaft and have it make a complete rotation.
4.5 Preservation (inside)
Shut off the suction flange imperviously. Fill the pump with preservative and slowly turn the rotating
parts by hand. Then shut off the delivery flange imperviously.
4.5.1 Control of preservation
Every 3 months the level of the liquid must be checked and the rotating parts manually turned to prevent
seizing. Top up preservative as necessary.
4.5.2 Removal of the preservative
Before the pump is brought into use the pump must be thoroughly rinsed. Make sure that the rinsing agent
does not arrive in the environment! When adding preservative again the old preservative must first be
removed.
Make sure that the preservative does not leak from the pump during transport
and manoeuvring. A leaking pump/pump unit can
cause dangerous situations.
4.6 General operating instructions for centrifugal pumps
Because of the amount of available versions and pumping principles only general instructions can be
given here. These are normally sufficient for experienced installation technicians. When in doubt always
consult your supplier and/or ask for detailed information about the pump unit.
4.7 Construction
Centrifugal pumps can be supplied with or without diesel/electric motor, with shared, rigid or flexibly
coupled pump and motor shaft, in horizontal or vertical versions, in a number of material designs, in a
number of construction sizes and with different seals. The pumps are supplied as normally priming and
self-priming versions.
