Equipment mounting surfaces should be utilized to
establish level.
ALIGNMENT AND ALIGNMENT CRITERIA
Alignment procedures must be followed to prevent
unintended contact of rotating parts. Follow coupling
manufacturer's installation and operation procedures.
• After First Run -To obtain correct alignment when
both pump and driver are at operating temperature.
Thereafter, alignment should be checked periodically in
accordance with plant operating procedures.
NOTE: Alignment check must be made if process
temperature changes, piping changes, and/or pump
service is performed.
Alignment is achieved by adding or removing shims from
under the driver and/or shifting driver horizontally as
needed.
Final Alignment (Hot Alignment) is done after operation
when the pump and driver are at operating temperatures.
NOTE: Proper alignment is the responsibility
of the installer and user of the unit.
Accurate alignment of the equipment must be attained.
Trouble-free operation can be accomplished by achieving
alignment within the levels specified in the following
section.
Three common alignment methods are utilized:
1-Reverse Dial Indicator method is most common.
2-Laser method is similar to reverse dial indicator
method, but uses a laser to obtain the necessary
measurements.
3-Dial Indicator
(rim-and-face) method.
GENERAL CONSIDERATIONS
To remove coupling guard, refer to coupling guard
installation and disassembly instructions in
Appendix
II .
Initial Alignment (Cold Alignment) is done prior to
operation when the pump and the driver are at ambient
temperatures.
1-Before Grouting Baseplate -To ensure alignment can be
obtained.
2-After Grouting Baseplate -To ensure pipe strains haven’t
altered alignment. If changes have occurred, alter piping to
remove pipe strains on pump flanges.
Follow alignment equipment manufacturers’ procedures
when utilizing reverse dial indicator or laser methods. A
detailed procedure for alignment using the dial indicator
(rim-and-face) method is included as
Appendix III.
