local environment management. according to the laws into force and to a safe local environment
management.
ATT.: If the pump will be stored, as foreseen in our Operating Manuals, we recommend a proper care to
avoid oil dropping on the ground.
The pump or assembly must
ALWAYS be moved and transported in the horizontal position.
Prior to moving the unit find the following:
- total weight
- centre of gravity
- maximum outside dimensions
- lifting points location.
For safe lifting to prevent material damages and/or personal injuries, it is recommended to use ropes, or
belts properly positioned on the pump and/or lifting eyebolts and make correct movements.
Lifting eyebolts fitted on single components of the assembly (pump or motor) should not be used to lift
the total assembly.
The fig. 1 and 2 show several additional examples of lifting.
Avoid lifts whereby the ropes or straps, form a triangle with the top angle over 90°(see fig. 3).
The methods of lifting as shown in fig. 4 are to be
absolutely avoided . Lifting the pump from the shaft end must be
avoided. Should the pump relocation be required, after it has been in use,the pump and its respective auxiliary piping and
interior must be emptied and cleared of service liquid. All its openings which lead to the inside of the pump have to be
well closed and sealed; for removal from the installation see chapter 15.
