4.4.1 Alignment checks
When to perform alignment checks
You must perform alignment checks under these circumstances:
•

•
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.
