Motor installation and coupling alignment
WARNING:
• 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.
• 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/gear manufacturer's 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.
Install the motor
Use NEMA Vertical C-face motors with this pump. P-base motor adapters and IEC motor
adapters are available as options.
1. Install both coupling halves before you mount the motor.
Refer to the instructions from the coupling manufacturer.
2. Use the lifting lugs on the motor in order to carefully lower the motor onto the pump.
Make sure to align the bolt holes.
3. Before you connect the coupling, wire the motor and check the direction of rotation.
The rotation arrow is on the motor support. The correct rotation is clockwise as you look
down from the drive at the impeller.
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)
check
Prior to operation when the pump and the driver are at ambient
temperature.
Final alignment (hot alignment)
check
After operation when the pump and the driver are at operating
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.
