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.

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.
