4. Transport and storage
4.1. Delivery
On delivery, check immediately that the ship -
ment 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. Claims made after this date cannot be
recognised. Damage to parts must be noted on
the freight documentation.
4.2. Transport
Only the designated and approved fastening
devices, transportation and lifting equipment
may be used for transportation. These must have
sufficient load-bearing capacity to ensure that
the pump can be transported safely. If chains are
used they must 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 nor -
mally precludes the possibility of damage occur-
ring during transport and storage. The packaging
should be stored in a safe place for reuse if the
product is frequently used at different locations.
4.3. Storage
Newly supplied pumps are prepared so that they
can be stored for at least 1 year. The pump should
be cleaned thoroughly before it is put into tem-
porary storage.
The following should be taken into consideration
for storage:
• Place the pump securely on a solid surface and
secure it against slipping. Submersible sewage
pumps must be stored upright.
