Baseplate Shims or wedges Foundation Sleeve Dam Bolt 1. 2. 3. 4. 5. Baseplate Shims or wedges Foundation Dam Bolt J-type bolts Baseplate-mounting procedures Prepare the baseplate for mounting This procedure assumes you have a basic knowledge of baseplate and foundation design and installation methods.
Installation 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.
Installation 2. Adjust the leveling jackscrews, located adjacent to the foundation bolt holes, until the baseplate rests 1 to 2 in. (25 to 50 mm) above the foundation in order to allow for adequate grouting. This provides even support for the baseplate after grouting. 3. Level the baseplate to within 0.002 in./ft. (0.167 mm/m) of the length or width of the baseplate by adjusting the jackscrews. • The maximum total variation from one end or side of the baseplate to the other is 0.015 in. (0.38 mm).
Installation 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 Initial alignment (cold alignment) check Final alignment (hot alignment) check When it is used Prior to operation when the pump and the driver are at ambient temperature. After operation when the pump and the driver are at operating temperature.
Installation Guideline Make sure that the hold-down bolts for the driver feet are tight when you take indicator measurements. Make sure that the hold-down bolts for the driver feet are loose before you make alignment corrections. Check the alignment again after any mechanical adjustments. Explanation This keeps the driver stationary since movement causes incorrect measurement. This makes it possible to move the driver when you make alignment corrections.
Installation 1. Shims Figure 7: Example of incorrect vertical alignment (side view) 4. Repeat the previous steps until the permitted reading value is achieved. Perform angular alignment for a horizontal correction 1. Set the angular alignment indicator (A) to zero on 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.
Installation When the reading value is... Negative Positive Then... 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. 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 Figure 9: Example of incorrect vertical alignment (side view) 4.
Installation 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.
