Commissioning, Startup, Operation, and Shutdown
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.
• 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.
• 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.
•
Alignment procedures must be followed to prevent unintended contact of rotating parts. Follow
coupling manufacturer’s installation and operation procedures.
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.
Doweling the pump casing
You must dowel the pump casing to the baseplate pedestals in order to maintain the proper
pump position. There are two methods for doweling the pump casing.
When the driver is mounted at the factory, the pump is doweled; the driver is not doweled in
order to allow for final field alignment. When the driver is mounted in the field, the pump is not
doweled. Therefore, these doweling procedures, typically done at the factory, must be done in
the field.
NOTICE:
You should dowel only after completing the final alignment.
Dowel for motor installation
1. Center the pump on its pedestal so that the hold-down bolts are centered in the tapped
holes of the pump pedestal.
2. Place the motor on the baseplate with the proper shaft separation (DBSE = distance
between shaft ends).
3. Tighten the pump hold-down bolts.
4. After you have determined the correct motor location on the motor pedestals, mark the
location of the motor on the pedestals with a hole punch through the hold-down bolt holes
in the motor feet.
5. Remove the motor, then drill and tap the punched holes on the motor pedestal.
NOTICE:
Scribe the motor shims in order to return them to the correct location on the motor pedestal.
