12.2 Base Leveling
Check if the base plate is equally resting on its chock blocks. If it is OK, place and tighten uniformly the nuts on the
foundation bolts. With the help of a precision level, check the leveling of the base longitudinally and transversally.
If the base is out of level, loosen the foundation bolts nuts and insert shims, as necessary, between the metallic chock block
and the base, so as to correct the leveling. See fig. 10.

12.3 Grouting
For secure and fastening vibration-free, the pump base must be filled.
Grout should be composed of specific compounds available in the construction appliance market which prevent shrinkage
through grout setting as well as full base filling and do not allow blanks or gapes. See fig. 11.

12.4 Coupling alignment
The useful lift of the turning assembly and its operation free of irregular vibrations will rely on the perfect alignment between
the pump and the driver.
The alignment performed at the factory must be remade because during transportation and handling, the motor-pump
assembly is subjected to deformations, which affect the initial alignment.
After the complete set of the grout, perform the alignment, if possible, with the suction and discharge pipe lines already
connected.
This alignment should be performed with the help of a dial indicator for the control of the radial and axial displacements.
Fix the bottom of the instrument to the periphery of one the coupling halves, adjust the position of the feeler perpendicular to
the periphery of the other half of the coupling. Move the dial to zero and move manually the coupling half in which the
instrument basis is fixed, making the dial complete a 360 degrees turn. See Fig. 12. The same procedure should be
performed to control the axial displacement.
See fig. 13.
