Baseplate-mounting procedures
Prepare the baseplate for mounting
This procedure assumes you have a basic knowledge of baseplate and foundation design and installation methods. Follow industry-standard procedures, such as API RP 686/ PIP REIE 686, or this procedure before you grout the baseplate.
1.Make sure that all baseplate surfaces that will contact grout are free from contamination such as rust, oil, and grime.
2.Thoroughly clean all baseplate surfaces that will come in contact with grout. Make sure to use a cleaner that will not leave residue.
20 Model 3700, API Type OH2 / ISO 13709 1st and 2nd Ed. / API 610 8/9/10/11th Ed. Installation, Operation, and Maintenance Manual
Installation
NOTICE:
You may need to sandblast the surfaces of a baseplate that come in contact with grout, and then coat those surfaces with a primer that is grout-compatible. Make sure to remove all equipment before sandblasting.
3.Make sure that all machined surfaces are free from burrs, rust, paint, or any other type of contamination.
If necessary, use a honing stone to remove burrs.
Prepare the foundation for mounting
1.Chip the top of the foundation to a minimum of 1.0 in. (25.0 mm) in order to remove porous or low-strength concrete.
If you use a pneumatic hammer, make sure that it does not contaminate the surface with oil or other moisture.
NOTICE:
Do not chip the foundation using heavy tools such as jackhammers. This can damage the structural integrity of the foundation.
2.Remove water or debris from the foundation bolt holes or sleeves.
3.If the baseplate uses sleeve-type bolts, then fill the sleeves with a non-binding, moldable material. Seal the sleeves in order to prevent the grout from entering.
4.Coat the exposed portion of the anchor bolts with a non-bonding compound such as paste wax in order to prevent the grout from adhering to the anchor bolts.
Do not use oils or liquid wax.
5.If recommended by the grout manufacturer, coat the foundation surface with a compatible primer.
Install the baseplate using jackscrews
Tools required:
•Anti-seize compound
•Jackscrews
•Bar stock
•Two machinist's levels
This procedure is applicable to the feature-fabricated steel baseplate and the advantage base baseplate.
1.Apply an anti-seize compound on the jackscrews.
The compound makes it easier to remove the screws after you grout.
2.Lower the baseplate carefully onto the foundation bolts and perform these steps:
a)Cut the plates from the bar stock and chamfer the edges of the plates in order to reduce stress concentrations.
b)Put the plates between the jackscrews and the foundation surface.
c)Use the four jackscrews in the corners in order to raise the baseplate above the foundation.
Make sure that the distance between the baseplate and the foundation surface is between 0.75 in. (19 mm) and 1.50 in. (38 mm).

3.Level the driver mounting pads:
NOTICE:
Remove all dirt from the mounting pads in order to make sure that you achieve the correct leveling. Failure to do so can result in equipment damage or decreased performance.
a) Put one machinist's level lengthwise on one of the two pads. b) Put the other machinist's level across the ends of the two pads.
c)Level the pads by adjusting the four jackscrews in the corners.
Make sure that the machinist's level readings are as close to zero as possible, both lengthwise and across.
4.Turn the center jackscrews down so that they rest on their plates on the foundation surface.
5.Level the pump mounting pads:
NOTICE:
Remove all dirt from the mounting pads in order to make sure that you achieve the correct leveling. Failure to do so can result in equipment damage or decreased performance.
a)Put one machinist's level lengthwise on one of the two pads.
b)Put the other level across the center of the two pads.
c)Level the pads by adjusting the four jackscrews in the corners.
Make sure that the machinist's level readings are as close to zero as possible, both lengthwise and across.
6.Hand-tighten the nuts for the foundation bolts.
7.Check that the driver's mounting pads are level and adjust the jackscrews and the foundation bolts if necessary.
The correct level measurement is a maximum of 0.002 in./ft (0.0167 mm/m).
The maximum variation from one side of the baseplate to the other is 0.015 in. (0.38 mm).
Install the pump, driver, and coupling
1.Mount and fasten the pump on the baseplate. Use applicable bolts.
2.Mount the driver on the baseplate. Use applicable bolts and hand tighten.
3.Install the coupling.
See the installation instructions from the coupling manufacturer.

Pump-to-driver alignment
Precautions
WARNING:
•Follow shaft alignment procedures in order to prevent catastrophic failure of drive components or unintended contact of rotating parts. Follow the coupling installation and operation procedures from the coupling manufacturer.
•Always disconnect and lock out power to the driver before you perform any installation or maintenance tasks. Failure to disconnect and lock out driver power will result in serious physical injury.
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.
Alignment methods
Three common alignment methods are used:
•Dial indicator
•Reverse dial indicator
•Laser
Follow the instructions from the equipment manufacturer when you use the reverse dial indicator or laser methods. Detailed instructions for using the dial indicator method are contained in this chapter.
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 |

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. |
|
If changes have occurred, you must alter the piping to remove pipe |
|
strains on the pump flanges. |
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. You must use the correct tolerances. Failure to do so can result in misalignment and reduced pump reliability.
IMPORTANT
•For electric motors, the motor shaft initial (cold) parallel vertical alignment setting should be 0.002 to 0.004 in. (0.05 to 0.10 mm) lower than the pump shaft.
•For other drivers such as turbines and engines, follow the driver manufacturer's recommendations.
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 indicator runout is a maximum of 0.002 in. (0.05 mm) at operating temperature.
•The tolerance of the indicator is 0.0005 in./in. (0.0127 mm/mm) of indicator separation at operating temperature.

Attach the dial indicators for alignment
You must have two dial indicators in order to complete this procedure.
1.Attach two dial indicators on the pump coupling half (X):
a)Attach one indicator (P) so that the indicator rod comes into contact with the perimeter of the driver coupling half (Y).
This indicator is used to measure parallel misalignment.
b)Attach the other indicator (A) so that the indicator rod comes into contact with the inner end of the driver coupling half.
This indicator is used to measure angular misalignment.

Refer to the alignment table in "Permitted indicator values for alignment checks" (see Table of Contents for location of table) for the proper cold alignment value based on the motor temperature rise and the pump operating temperature.
Before you start this procedure, make sure that the dial indicators are correctly set up. A unit is in parallel alignment when the parallel indicator (P) does not vary by more than 0.002 in. (0.05 mm) as measured at four points 90° apart at the operating temperature.
1.Set the parallel alignment indicator (P) to zero at the top-center position (12 o’clock) of the driver coupling half (Y).
2.Rotate the indicator to the bottom-center position (6 o’clock).
3.Record the indicator reading.
When the reading value is... |
Then... |
Negative |
The pump coupling half (X) is lower than the |
|
driver coupling half (Y). Remove shims of a |
|
thickness equal to half of the indicator reading |
|
value under each driver foot. |
Positive |
The pump coupling half (X) is higher than the |
|
driver coupling half (Y). Add shims of a thickness |
|
equal to half of the indicator reading value to each |
|
driver foot. |
NOTICE:
1. Shims

4. Repeat the previous steps until the permitted reading value is achieved.
Perform parallel alignment for a horizontal correction
A unit is in parallel alignment when the parallel indicator (P) does not vary by more than 0.002 in. (0.05 mm) as measured at four points 90° apart at the operating temperature.
1.Set the parallel alignment indicator (P) to zero on the left side of the driver coupling half (Y), 90° from the top-center position (9 o’clock).
2.Rotate the indicator through the top-center position to the right side, 180° from the start position (3 o’clock).
3.Record the indicator reading.

5. Repeat the previous steps until the permitted reading value is achieved.
Perform complete alignment for a vertical correction
A unit is in complete alignment when both the angular indicator (A) and the parallel indicator (P) do not vary by more than 0.002 in. (0.05 mm) as measured at four points 90° apart.
1.Set the angular and parallel dial indicators to zero at the top-center position (12 o’clock) of the driver coupling half (Y).
2.Rotate the indicators to the bottom-center position (6 o’clock).
3.Record the indicator readings.
4.Make corrections according to the separate instructions for angular and parallel alignment until you obtain the permitted reading values.

Grout the baseplate
Required equipment:
•Cleaners: Do not use an oil-based cleaner because the grout will not bond to it. See the instructions provided by the grout manufacturer.
•Grout: Non-shrink grout is recommended.
NOTICE:
It is assumed that the installer who grouts the baseplate has knowledge of acceptable methods. More detailed procedures are described in various publications, including API Standard 610, latest edition, Appendix L; API RP 686, Chapter 5; and other industry standards.
1. Clean all the areas of the baseplate that will come into contact with the grout.

2.Build a dam around the foundation.
3.Thoroughly wet the foundation that will come into contact with the grout.
4.Pour grout through the grout hole into the baseplate up to the level of the dam. When you pour the grout, remove air bubbles from it by using one of these methods:
•Puddle with a vibrator.
•Pump the grout into place.
5.Allow the grout to set.
