3. Transport and storage

3.1. Delivery

On delivery, immediately check that the prod-
uct 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
recognized. Damage to parts must be noted on
the delivery or freight documentation.

3.2. Transport

Only the appropriate and approved fastening de-
vices, transportation means and lifting gear may
be used. These must have sufficient load-bearing
capacity to ensure that the pump can be trans-
ported 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
regulations 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.

3.3. Storage

Newly supplied units 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 on a firm surface and secure it
against slipping and falling over. Submersible mo-
tor pumps can be stored vertically and horizon-
tally. When horizontally storing pumps with more
than 9 stages, ensure that they cannot bend.
otherwise, excessive bending tension in the hy-
draulics may arise, which can damage the pump.
Support the hydraulics accordingly!
DANGER from falling over!
Never set down the unit unsecured.
If the pump falls over, injury can occur!
• Our units can be stored at temperatures down
to -15 °C. The store room must be dry. We recom-
mend a frost-protected room for storage with
a temperature between 5 °C and 25 °C.
• The unit may not be stored in rooms where weld-
ing work is conducted as the resulting gases and
radiated 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.

TRANSPORT AND STORAGE
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. Therefore,
never immerse cable ends in the pumped
liquid or other liquids.
• The unit must be protected from direct sunlight,
heat, dust, and frost. Heat and frost can cause
considerable damage to rotors and coatings!
• If the unit has been stored for a long period of
time it should be cleaned of impurities such as
dust and oil deposits before start-up. Check that
the impellers run smoothly.
If these rules are observed, your unit can be
stored for a lengthy 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. Consult the
manufacturer for details.

3.4. Return delivery

Pumps that are returned to the factory must be
properly packaged. This means that impurities
have been removed from the unit and that it has
been decontaminated if used with fluids that are
hazardous to health. The packaging must protect
the unit from damage during transportation.
If you have any questions please contact the
manufacturer.

4. Product description

The pump is manufactured with great care and is
subject to constant quality controls. Trouble-free
operation is guaranteed if it is installed and main-
tained correctly.

4.1. Proper use and fields of application

The submersible motor pumps are suitable:
• For supplying water from boreholes, wells and
cisterns
• For private water supplies, sprinkler and flood
irrigation
• For pumping water without fibrous or abrasive
materials
Submersible motor pumps must not be used
for pumping:
• Waste water
• Sewage/feces
• Raw sewage
