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.
Final alignment (hot alignment) checks
When Why
After the first run This ensures correct alignment when both the pump and the driver are at op-
erating temperature.
Periodically This follows the plant operating procedures.
4.3.1.1 Cold settings for parallel vertical alignment
Introduction
This section shows the recommended preliminary (cold) settings for electric motor-driven pumps based
on different temperatures of pumped fluid. Consult driver manufacturers for recommended cold settings
for other types of drivers such as steam turbines and engines.
Recommended settings
Pumped fluid temperature Recommended setting for driver shaft
Ambient 0.05 mm | 0.002 in. to 0.102 mm | 0.004 in., low
38°C | 100°F 0.00 mm | 0.000 in. to 0.05 mm | 0.002 in, high
93°C | 200°F 0.102 mm | 0.004 in. to 0.152 mm | 0.006 in., high
149°C | 300°F 0.203 mm | 0.008 in. to 0.254 mm | 0.010 in., high
204°C | 400°F 0.305 mm | 0.012 in. to 0.356 mm | 0.014 in., high
4.3.2 Align the pump using a straight edge
Before you begin, you must have a straight edge and a taper gauge or set of feeler gauges.
Only use this method if the face and outside diameters of the coupling halves are square and concentric
with the coupling bores. If this condition does not exist or elastomeric couplings do not make this method
convenient, then use the dial indicator method.
1. Check for angular alignment by inserting the taper or feeler gauges between the coupling faces at
90° intervals.
The unit is in angular alignment when these four measurements are the same or are within recom-
mended tolerances.
2. Check for parallel alignment by placing a straight edge across both coupling rims on all four sides.
The unit is in parallel alignment when the straight edge rests evenly across both coupling rims in all
four positions.
