Goulds Pumps API 3171 - IOM - Manual (Page 40)

Make the final alignment of the pump and driver
WARNING:
• 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.
• 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.
You must check the final alignment after the pump and driver are at operating temperature. For initial
alignment instructions, see the Installation chapter.
1. Run the unit under actual operating conditions for enough time to bring the pump, driver, and
associated system to operating temperature.
2. Shut down the pump and the driver.
3. Remove the coupling guard.
See Remove the coupling guard in the Maintenance chapter.
4. Check the alignment while the unit is still hot.
See Pump-to-driver alignment in the Installation chapter.
5. Reinstall the coupling guard.
6. Restart the pump and driver.
