• The piping changes.
• The pump has been serviced.
Types of alignment checks
Type of check
Initial alignment (cold alignment)
check
Final alignment (hot alignment) check After operation when the pump and the driver are at operating temperature.
Initial alignment (cold alignment) checks
When

Electrical connections must be made by certified electricians in compliance with all
international, national, state, and local rules.
Refer to driver/coupling/gear manufacturer's installation and operation manuals
(IOM) for specific instructions and recommendations.
When it is used
Prior to operation when the pump and the driver are at ambient temperature.
Why
This ensures that alignment can be accomplished.
This ensures that no changes have occurred during the grouting process.
This ensures that pipe strains have not altered the alignment.
Why
This ensures correct alignment when both the pump and the driver are at op-
erating temperature.
