4.4.1 Alignment checks
When to perform alignment checks
You must perform alignment checks under these circumstances:
• The process temperature changes.
• The piping changes.
• The pump has been serviced.
Types of alignment checks
Type of check When it is used
Initial alignment (cold alignment)
check Prior to operation when the pump and the driver are at ambient temperature.
Final alignment (hot alignment) check After operation when the pump and the driver are at operating temperature.
Initial alignment (cold alignment) checks
When Why
Before you grout the baseplate This ensures that alignment can be accomplished.
After you grout the baseplate This ensures that no changes have occurred during the grouting process.
After you connect the piping This ensures that pipe strains have not altered the alignment.
If changes have occurred, you must alter the piping to remove pipe strains
on the pump flanges.
Final alignment (hot alignment) checks
When Why
After the first run This ensures correct alignment when both the pump and the driver are at op-
erating temperature.
Periodically This follows the plant operating procedures.
4.4.2 Permitted indicator values for alignment checks
NOTICE:
The specified permitted reading values are valid only at operating temperature. For cold set-
tings, other values are permitted. The correct tolerances must be used. Failure to do so can
result in misalignment. Contact ITT for further information.
IMPORTANT
• The driver shaft initial (cold) parallel vertical alignment setting should be lower than the pump shaft.
Follow the driver manufacturer's recommendations.
When dial indicators are used to check the final alignment, the pump and drive unit are correctly aligned
when these conditions are true:
• The Total Indicated Reading (T.I.R.) is at 0.05 mm | 0.002 in. or less at operating temperature.
• The tolerance of the indicator is 0.0127 mm per mm | 0.0005 in. per in. of indicator separation for
the reverse dial indicator or laser method when the pump and driver are at operating temperature.
