Installation
Pump-to-driver alignment
Precautions
WARNING:
• Follow shaft alignment procedures in order to prevent catastrophic failure of drive components or
unintended contact of rotating parts. Follow the coupling installation and operation procedures from
the coupling manufacturer.
• Always disconnect and lock out power to the driver before you perform any installation or
maintenance tasks. Failure to disconnect and lock out driver power will result in serious physical
injury.
• Electrical connections must be made by certified electricians in compliance with all international,
national, state, and local rules.
• Refer to driver/coupling/gear manufacturers installation and operation manuals (IOM) for specific
instructions and recommendations.
NOTICE:
Proper alignment is the responsibility of the installer and the user of the unit. Check the
alignment of frame-mounted units before you operate the unit. Failure to do so can result in
equipment damage or decreased performance.
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) Prior to operation when the pump and the driver are at ambient
check temperature.
Final alignment (hot alignment) After operation when the pump and the driver are at operating
check 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 operating temperature.
Periodically This follows the plant operating procedures.
