2.6 Fluids
Each fluid differs in respect of composition, cor-
rosiveness, abrasiveness, dry matter content and
in many other aspects. Generally, our pumps can
be used for many applications. Please note that if
requirements change (density, viscosity or general
composition), this can also affect many operating
parameters of the pump.
When using and/or replacing the pump in a differ-
ent fluid:
• The motor is filled with oil. The fluid can be
contaminated by this oil if the mechanical seal is
defective.
• When used in drinking water applications, all the
parts in contact with fluid must be fit for the pur-
pose. This must be checked in accordance with
the local regulations and laws.
The pumps must not be used in wastewater and
sewage and/or with fluids that are hazardous to
health.

2.7 Sound pressure

The submersible pump generates a sound-pres-
sure level of approx. 70 dB (A) during operation.
However, the actual sound-pressure level
depends on several factors. These include, for
example, the installation depth, installation,
fixation of accessories and piping, the duty point,
immersion depth, etc.
We recommend that the operator should take an
additional measurement at the workplace once
the unit is running at its duty point and under all
operating conditions.
CAUTION: wear ear defenders!
According to applicable laws and regula-
tions, ear protection must be worn if the
sound-pressure level is 85 dB (A) or more! The
end-user must make sure that this is complied
with!
2.8 CE marking
The CE marking is attached to the rating plate.

3 Transportation and storage

3.1 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 cannot be made after-
wards.
Damage to parts must be noted on the freight
documentation.
3.2 Transport
Only the appropriate and approved lifting gear,
means of transportation and hoisting gear may
be used for transportation. 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.

TRANSPORTATION AND STORAGE
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 oc-
curring during transportation and storage. Store
the packaging safely for reuse if the product is
frequently used at different locations.
3.3 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 stor-
age!
Observe the following when putting into
storage:
• Place the pump on a firm bearing surface and se-
cure it against slipping and falling over. Submersi-
ble pumps can be stored vertically or horizontally.
If pumps with more than 9 stages are stored
horizontally, ensure that they do not bend.
Otherwise, impermissible bending tensions can
arise in the hydraulics and the pump may be
damaged. In order to avoid damage, support the
hydraulics accordingly!
DANGER due to risk of falling over!
Never set the unit down unsecured. If the
pump falls over, there is a risk of injury!
• Submersible pumps can be stored at tempera-
tures down to max. -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.
• It is not permissible to store the submersible
pump in rooms where welding work is carried out,
because the resulting gases or radiation can dam-
age the elastomer components and coating.
• The pump's suction and pressure connections
should be permanently sealed to prevent con-
tamination.
• The power supply cables should be protected
against kinking, damage, and moisture.
DANGER due to electrical current!
Damaged power supply cables can cause fatal
injury! Defective cables must be replaced by a
qualified electrician immediately.
CAUTION: 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 must be protected from
direct sunlight, heat, dust, and frost.
• If the submersible pump has been stored for a
long period of time, it should be cleaned of impu-
rities such as dust and oil residue before commis-
sioning. Check the impeller for ease of movement.
