3.2.2- Lifting operation
- Total weight and centre of gravity,
- The largest outer dimensions, and
- Location of the lifting points.
• The load lifting capacity should comply with the weight of the pump or pump group.
• The pump or pump group should always be lifted and handled horizontally.
• Never stand under or near the load being lifted.
• Do not keep the load lifted longer than necessary.
• Accelerating and braking operations during the hoisting should not be performed in such a way that
may be dangerous for the working personnel.
The pump or pump group should be hoisted as shown in the Figure 1a or Figure 1b in order to avoid
from any deformation. (When the group is hoisted as a whole, never use the suspension hook of the
electric motor.
3.3- Storage
• If the pump will not be installed in place immediately, it should be stored at a clean and dry place
free of any frost hazard without excessive change in the ambient temperature.
• If the electric motor bearings are of grease-applied ones, extra grease should be applied to the
bearings to prevent moisture ingress around the shaft.
• Necessary precautions should be taken to protect the pump against humidity, dust, dirt and foreign
materials.
• The pump should be rotated manually by some turns occasionally (e.g. once in a week) to prevent
pitting on the bearing surfaces and sticking of the pump.
ATTENTION
• Determine the following points prior to lifting and handling the pump.
