4 Transportation and storage

4.1 Delivery
On receiving the consignment, check immediately
that this is complete and undamaged. If any parts
are damaged or missing, the transport company
or the manufacturer must be notified on the day
of delivery since claims made after this date can-
not be recognised.
Damage to parts must be noted on the freight
documentation.
4.2 Transport
Only the appropriate and approved lifting gear,
transportation and hoist may be used. These
must have sufficient load-bearing capacity to
ensure that the pump can be transported safely.
When using chains, these are to be secured
against slipping.
The personnel must be qualified for the tasks and
must follow all applicable national safety regula-
tions during the work.
The pump is delivered by the manufacturer or
shipping agency in suitable packaging. This
normally precludes the possibility of damage
occurring during transportation and storage. The
packaging should be stored in a safe place for
reuse if the product is frequently used at different
locations.

TRANSPORTATION AND STORAGE
4.3 Storage
Newly delivered submersible pumps are prepared
in such a way that they can be stored for at least
1 year. The pump should be cleaned thoroughly
before it is put into temporary storage!
Consider the following for storage:
• Place the pump on a firm bearing surface and se-
cure it against slipping and falling over. Submers-
ible pumps can be stored vertically or horizontally.
If pumps are stored horizontally in more than
9 layers, ensure that they do not bend.
Otherwise, impermissible bending tensions can
arise in the hydraulics and the pump may be
damaged. Support the hydraulics accordingly!
DANGER due to falling over!
Never set the unit down unsecured. If the
pump falls over, this may lead to injuries!
• Submersible pumps can be stored at tempera-
tures down to -15 °C. The store room must be dry.
We recommend a frost-protected room for stor-
age with temperature between 5 °C and 25 °C.
• The submersible pump is not allowed to be stored
in rooms in which welding work is carried out, be-
cause the resulting gases or radiation can damage
the elastomer components and coating.
• The pump's suction and pressure connections
and the external frequency converter should be
permanently sealed to prevent contamination.
• The power supply cables should be protected
against kinking, damage, and moisture.
ELECTRICAL hazard!
Damaged power supply cables can cause fatal
injury! Defective cables must be replaced by a
qualified electrician immediately.
BEWARE of moisture!
Moisture penetrating the cable will damage
both the pump and the cable. For this reason,
never immerse the cable end in the fluid or
any other liquid.
• The submersible pump and the external fre-
quency converter must be protected from direct
sunlight, heat, dust, and frost.
• If the submersible pump and the external fre-
quency converter have been stored for a long pe-
riod of time, they should be cleaned of impurities
such as dust and oil residue before commission-
ing. Check the impeller for ease of movement.
Note:
Elastomer parts and coating are subject to natural
brittleness. If the product is to be stored for
longer than 6 months, we recommend check-
ing these parts and replacing them as necessary.
Consult the manufacturer for further details.
