
The product may not be stored in rooms where welding work is conducted as the resulting gases
and radiation can damage the elastomer parts and coatings.

It is responsible to take care that the corrosion coating will not be spoiled

Any suction or pressure connections on products should be closed tightly before storage to prevent
impurities.

The power 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 damp!
Moisture penetrating cables can damage them and render them useless. Therefore, never immerse cable
ends in the pumped fluid or other liquids.

The machine must be protected from direct sunlight, heat, dust, and frost. Heat and frost can cause
considerable damage to propellers, rotors and coatings.

The rotors or propellers must be turned at regular intervals. This prevents the bearing from locking
and the film of lubricant on the mechanical shaft seal is renewed. This also prevents the gear
pinions (if present on the product) from becoming fixed as they turn and also renews the lubricating
film on the gear pinions (preventing rust film deposits).
Beware of sharp edges!
Sharp edges can form on rotors and propellers. There is a risk of injuries. Wear protective gloves.

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 and propellers should be checked for smooth running,
housing coating and damage.

After storage longer than one year the oil of motor and, if necessary the gear have to be changed.
This is also necessary if the product never had run (natural deterioration of oil).
Before start-up, the filling levels (oil, cooling fluid etc.) of the individual products should be checked and
topped up if required. Please refer to the machine data sheet for specifications on filling. Damaged
coatings should be repaired immediately. 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 naturally. If the product is to be stored for longer than 6 months, we recommend
checking these parts and replacing them as necessary. Please consult the manufacturer.

4.4. Returning to the supplier

Products which are delivered to the plant must be clean and correctly packaged. In this context, clean means that
impurities have been removed and decontaminated if it has been used with materials which are hazardous to
health. The packaging must protect the product against damage. Please contact the manufacturer before
returning!

5. Installation and Start-Up

5.1. General
The following points must be noted to prevent damages in the pump during installation and commissioning:

The installation work must be carried out by qualified personnel in compliance with the safety
regulations.

The pump must be checked for possible damages prior to installation.

The minimum submersion in water must be considered for level control.

Air pockets in the pump casing and in pipes must be avoided (by means of appropriate venting
facilities or slight tilting of the pump).

Protect the pump from frost.

The mechanical room must be designed for the respective machinery. This includes also that a
lifting device for assembly/disassembly can be installed, with which the installation site of the pump
can be reached without danger.

The lifting device must have a maximal lifting power which is above the weight of the pump with
mounting parts and cable.

The power lines of the pump must run in a way that hazard-free operation and easy
assembly/disassembly is possible.
