Installation, Operation & Maintenance Manual
6. Restart the pump and driver.
Dowelling the driver (Optional)
After the unit has been running for about one week, the coupling halves must be given a final
check for possible misalignment caused by pipe strain or temperature strains. This check
must be made immediately after unit is shut down, before it has a chance to cool.
If alignment is correct and unless Circor instructs otherwise, the driver should be doweled on
diagonally opposite foot locations. Normally the pumps are doweled at the factory and the
drivers are doweled in the field. The taper pin size for doweling the driver
Position will normally be the same as the pump.
There are two methods employed by the factory for doweling the pump casing, depending on
whether the pump is operated in an application with a low or high temperature differential
between the ambient temperature during setup and the temperature of the pumped fluid.
If the temperature differential is low the pump foot on the drive end of the pump will require
taper pins installed to secure the pump to the baseplate
If the temperature differential is high the baseplate is supplied with provision to accommodate
differential temperature doweling. This design ensures the alignment between the pump and
driver is maintained while allowing the case to thermally move.
NOTICE:
You should dowel the driver only after completing the final hot alignment.
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.
4. Check and confirm the alignment while the unit is still hot.
5. Dowel the driver feet. See the driver IOM for details.
WARNING:
Failure to disconnect and lock out driver power may result in serious physical injury or death.
Always disconnect and lock out power to the driver before performing any installation or
maintenance tasks.
