3 Transport and storage
3.1 Delivery
Upon receipt of the delivery, it is immediately checked
for damage and completeness. If any parts are dam-
aged or missing, the transport company or the manu-
facturer must be informed on the day of delivery.
Claims made after this date cannot be recognized.
Damage to parts must be noted on the delivery or
freight documentation.
3.2 Transport
Only the appropriate and approved fastening devices,
transportation means and lifting gear may be used.
These must have sufficient load-bearing capacity to
ensure that the product can be transported safety. If
chains are used they must be secured against slipping.
The personnel must be qualified for the tasks and must
follow all national safety regulations in effect during the
work.
The product is delivered by the manufacturer / ship-
ping agency in suitable packaging. This normally pre-
cludes the possibility of damage occurring during
transport and storage. The packaging should be stored
in a safe place for reuse if the product is frequently
used at different locations.
Beware of frost!
If drinking water is used as a coolant/lubricant,
the product must be protected against frost dur-
ing transport. If this is not possible, the product
must be drained and dried out!
3.3 Storage
Newly supplied products are prepared so that they can
be stored for at least 1 year. The product should be
cleaned thoroughly before it is put into temporary
storage!
The following should be taken into consideration for
storage:
• Place the product on a firm surface and secure it
against slipping and falling over. Submersible motor
pumps can be stored vertically and horizontally. Ensure
that they cannot bend if stored horizontally.
Otherwise, excessive bending tension may arise,
which can damage the product.
Danger from falling over!
Never set down the product unsecured. If the
product falls over, injury can occur!
• Our products can be stored at temperatures down to
-15 °C. The store room must be dry. We recommend a
frost-protected room for storage with a temperature
between 5 °C and 25 °C.
Products that are filled with drinking water can
be stored in frost-free rooms at temperatures up
to 3 °C for up to 4 weeks. If longer storage is
intended, the products should be emptied and
dried out beforehand.

• The product may not be stored in rooms where weld-
ing work is conducted as the resulting gases and radi-
ated heat can damage the elastomer parts and
coatings.
• Any suction or discharge ports should be closed tightly
before storage to prevent impurities.
• The current supply cables should be protected against
kinking, damage, and moisture.
Beware of electrical current!
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 damages both
the product and cable. Therefore, never immerse
cable ends in the pumped liquid or other liquids.
• The machine must be protected from direct sunlight,
heat, dust, and frost. Heat and frost can cause consid-
erable damage to rotors and coatings!
• If the product has been stored for a long period of time
it should be cleaned of impurities such as dust and oil
deposits before start-up. Rotors should be checked for
smooth operation. The housing coatings should be
checked for damage.
Before start-up, the filling levels (oil, motor fill-
ing, etc) should be checked and topped up, if
necessary. Products filled with drinking water
should be completely filled before start-up!
Beware of damaged coatings!
Damaged coatings can lead to irreparable dam-
age to the unit (e.g. rust formation)! Therefore,
damaged coatings must be repaired immedi-
ately. Repair sets are available from the manu-
facturer.
Only a coating that is completely intact fulfills
the criteria for intended usage!
If these rules are observed, your product can be stored
for a longer period. Please remember that elastomer
parts and coatings become brittle over time. If the
product is to be stored for longer than 6 months, we
recommend checking these parts and replacing them
as necessary. If this is the case, please consult the
manufacturer.
3.4 Returning to the product
Products that are returned to the factory must be
properly packaged. In this context, properly means that
impurities have been removed from the product and
that it has been decontaminated, if it was used with
fluids that are hazardous to health. The packaging
must protect the product from damage during trans-
portation. If you have any questions please contact the
manufacturer!
