Model API 3171 Installation, Operation, and Maintenance Manual 23
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.
Permitted indicator values for alignment checks
NOTICE:
The specified permitted reading values are valid only at operating temperature. For cold
settings, other values are permitted. The correct tolerances must be used. Failure to do so can
result in misalignment.
When dial indicators are used to check the final alignment, the pump and drive unit are
correctly aligned when these conditions are true:
• The Total Indicated Reading (T.I.R.) is at 0.05 mm | 0.002 in. or less at operating
temperature.
• The tolerance of the indicator is 0.0127 mm per mm | 0.0005 in. per in. of indicator
separation for the reverse dial indicator or laser method when the pump and driver are at
operating temperature.
Align the coupling
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.
• Electrical connections must be made by certified electricians in compliance with all
international, national, state, and local rules.
• Refer to driver/coupling manufacturer's installation and operation manuals (IOM) for
specific instructions and recommendations.
• Misalignment can cause decreased performance, equipment damage, and even catas-
trophic failure of frame-mounted units leading to serious injury. Proper alignment is the
responsibility of the installer and the user of the unit. Check the alignment of all drive
components prior to operating the unit.
• Follow the coupling installation and operation procedures from the coupling manufactur-
er.
• When installing in a potentially explosive environment, ensure that the motor is
properly certified.
• The coupling used in an ATEX classified environment must be properly certified.
Alignment of the pump and motor is of extreme importance for trouble-free mechanical
operation. Straight-edge alignment by an experienced installer is adequate for most installa-
tions. Use dial indicators for disc couplings and applications where alignment to tighter
tolerances is desirable. In these cases, use standard dial indicator procedures.
1. Check for coupling alignment by using either the reverse dial indicator method or laser
alignment tools.
2. Move the motor until you achieve the correct alignment.
Refer to the coupling manufacturer literature for proper alignment criteria.
3. Install discs between the hubs per the manufacturer's directions included with the pump
data package.
4. Tighten all motor bolts.
Float control installation
ITT supplies several different float controls. Refer to the float control installation instructions
provided with the controls for the proper installation procedure. This topic describes the Square
D 9036 Simplex and Square D 9038 Duplex float controls.
