2.2 Guidelines for transport
Precautions
WARNING:
•
Observe the accident prevention regulations in force.
•
Risk of crushing. The unit and the components can be
heavy. Implement proper lifting methods and always
wear steel-capped boots.
Check the gross weight marked on the packaging in order to choose
suitable lifting equipment.
Installation and securing
The unit can be transported either horizontally or vertically. Make sure
that the unit is securely fastened during transportation, and cannot roll
or fall over.
WARNING:
Do not use eyebolts screwed on the motor for handling the
whole pump unit.
•
Use straps surrounding the motor if the power of the motor is between
0.25 kW and 4.0 kW.
•
Use ropes or straps that are linked to the two flanges (eye bolts if
provided) located near the mating zone between the motor and
pump, if the power of the motor is between 5.5 kW and 55.0 kW.
•
Eyebolts screwed onto the motor may be exclusively used to handle
the individual motor or, in case of a not balanced distribution of
weights, to partially lift the unit vertically starting from a horizontal
displacement.
•
To move only the pump unit, use the straps firmly fixed to the motor
adapter.
For more information about how to securely harness the unit, see
14
Unit without motor
If the unit is not delivered with a motor, the calibrated fork-shaped shim
is already inserted between the adapter and the transmission coupling.
The shim is inserted to keep the impeller stack in the correct axial
position. In order to prevent damage during transportation the shaft is
also held into place with expanded polystyrene and plastic straps.
The bolts and nuts needed to fasten the motor to the adaptor are not
included.
WARNING:
A pump and motor that are purchased separately and then
coupled together results in a new machine under the
Machinery directive 2006/42/EC. The person making the
coupling is responsible for all safety aspects of the combined
unit.
