Caution
Work on the machine must be carried out only during
standstill. The shutdown procedure described in the manual
for taking the machine out of service must be adhered to
without fail.
Pumps or pump units handling media injurious to health
must be decontaminated.
Immediately following completion of the work, all safety /
protective devices must be re-installed and / or re-activated.
Please observe all instructions set out In the chapter on
“Commissioning” before returning the machine to service.
2.7 Unauthorized Modification and Manufacture of
Spare Parts
Modifications or alterations of the machine are only
permitted after consultation with the manufacturer. Original
spare parts and accessories authorized by the manufacturer
ensure safety. The use of other parts can invalidate any
liability of the manufacturer for damage or warranty.
2.8 Unauthorized Modes of Operation
Any warranty of the operating reliability and safety of the
pump / unit supplied is only valid if the machine is operated
in accordance with its designated use as described in the
following sections. The limits stated in the data sheet must
not be exceeded under any circumstances.
3 Transport and Interim Storage
3.1 Transport
Proper lifting and safety practices must be observed at all
times. Lifting the pump assembly requires extreme care,
since the center of gravity is not located in the physical
center of the unit, but is usually closer to the stuffing box /
shaft seal area.
Never lift by a single point and do not use the pump or motor
shaft as a lift point. Eyebolt locations on the bearing
assembly and motor are intended for lifting those items only
and must not be used to lift the pump assembly.
At least four (4) connections are recommended to stabilize
the load, and they should be as far apart as practical. Avoid
excessive side loads on cast lifting eyes. Note that certain
lift points on the pedestal are intended for use in handling
the pedestal alone and are not necessarily optimum balance
points for the pump assembly.
Always make sure that the unit remains in the horizontal
position during transport and cannot slip out of the transport
suspension arrangement.
If the pump / unit slips out of the suspension
arrangement, it may cause personal injury and
damage to property.
Figures below give suggested lifting methods. Actual safe
lifting method will vary with pump configuration and type of
lifting equipment. Ensure secure attachments and test lifting
method for stability before moving pump.
In corrosive environments be sure to remove all lifting
devices from the pump and store in a non-corrosive
environment until needed.

3.2 Short Term Storage
The pump / unit should be stored in a dry room where the
atmospheric humidity is as constant as possible.
If stored outdoors, the unit and crates must be covered by
waterproof material to avoid any contact with humidity.
All openings of the assembled pump / unit components are
closed and must only be opened when required during
installation.
Protect all stored goods against humidity,
dirt, vermin and unauthorized access!
Short term storage requirements are defined for up to 3
months. For storage exceeding 3 months see Section 6.3 on
long term storage requirements.
