-Any hot or cold components that could pose a hazard must be equipped with a guard by the operator.

-Guards which are fitted to prevent accidental contact with moving parts (e.g. coupling) must not be removed whilst the unit is operating.

-Leakages (e.g. at the shaft seal) of hazardous fluids handled (e.g. explosive, toxic, hot) must be contained so as to avoid any danger to persons or the environment. All relevant laws must be heeded.

-Electrical hazards must be eliminated. (In this respect refer to the relevant safety regulations applicable to different countries and/or the local energy supply companies.)

2.6Safety instructions for maintenance, inspection and installation work

The operator is responsible for ensuring that all maintenance, inspection and installation work be performed by authorized, qualified specialist personnel who are thoroughly familiar with the manual.

Work on the machine / unit must be carried out only during standstill. The shutdown procedure described in the manual for taking the unit out of service must be adhered to without fail (section 6.3).

Pumps or pump units handling fluids injurious to health must be decontaminated.

Immediately following completion of the work, all safety-relevant and protective devices must be re-installed and / or re-activated.

Please observe all instructions set out in the chapter on ”Commissioning” (6.1) before returning the unit to service.

2.7Modification and manufacture of spare parts by customer

Modifications or alterations of the equipment supplied are only permitted with KSB’s prior approval. Original spare parts and accessories authorized by KSB ensure safety. The use of other parts will invalidate any liability of the manufacturer for consequential damage.

2.8Unauthorized modes of operation

The warranty relating to the operating reliability and safety of the pump is only valid if the machine is used in accordance with its designated use, i.e. with the technical data specified. For further details please refer to the information in section 4 of this operating manual. The limits stated in the data sheet must not be exceeded under any circumstances.

3Transport, storage

3.1Transport / Handling

to property!

Do not use lifting gear which may damage the pump (e.g. no chains).

Fig. 1 Transport of pump only

Fig. 2 Transport of pump unit

For transporting the unit, lifting ropes shall be attached to the pump and the motor as shown above. Never use the motor eyebolt for lifting the unit!

Fig. 3 Transport of close-coupled pumps and vertical pumps

3.2Storage / Preservation

Unless otherwise stated in the purchase order and order confirmation, the pumps are supplied by our factory duly preserved for a storage period of 3 months from delivery. We recommend to take the following additional measures if the pump is stored for a prolonged period of time prior to commissioning:

Indoor storage of new pumps:

New pumps are preserved for indoor storage in a dry, closed room in their original, unopened packaging for a maximum period of 3 months.

Caution Protect all stored goods against moisture, dirt, vermin and unauthorized access! All openings of the assembled unit components are closed and must only be

opened when required during installation.

Outdoor storage with the packaging unopened:

Protect the pump/unit against moisture, dirt, vermin and unauthorized access.

It is imperative to remove the preservative prior to normal commissioning by flushing through the system.

If the pump is to be stored for more than 3 months (optional, specified in the purchase order):

New pump/unit:

New pumps/units are specially preserved in the manufacturer’s factory.

It is imperative to remove the preservative prior to normal commissioning by flushing through the system.

Caution

The product used for this purpose is not suitable

 

for potable water systems and must be removed

completely by dismantling and subsequent cleaning of all parts of the pump coming into contact with the fluid handled, if required. For further information please refer to the order confirmation.

The unit/pump is installed some time before the system is commissioned:

Special measures have to be taken for prolonged shutdown periods, to make sure that the pump is always ready for instant start-up and to prevent the formation of deposits within the pump’s hydraulic system and intake area (see section 6.3.1).
