Grout baseplate in completely and allow grout to dry thoroughly before attaching
piping to pump (24 hours is sufficient time with approved grouting procedure).
3.6 Grouting procedure
Grout compensates for uneven foundation, distributes weight of unit and prevents
shifting. Use an approved, non-shrinking grout as follows, after setting and leveling
unit See Fig. 2.
a) Build strong form around foundation to content grout.
b) Soak top of concrete foundation thoroughly, then remove surface water.
c) Baseplate should be completely filled with grout and, if necessary, drill vent holes
to remove trapped air.
d) After grout has thoroughly hardened, check the foundation bolts and tighten if
necessary.
e) Check the alignment after the foundation bolts are tightened.
f) Approximately 14 days after the grout has been poured or when the Grout has
thoroughly dried, apply an oil base paint to the exposed edges of the grout to
prevent air and moisture from coming in contact with the grout.
3.7 Alignment procedure
The pump driver, if supplied, is correctly aligned on its base plate at the factory. A
certain amount of deformation of the base plate is possible during transit and it is
therefore essential to check alignment, prior to final grouting.
A flexible coupling will only compensate for small amount of misalignment and
should not be used to compensate for excessive misalignment of the pump and
driver shafts.
Inaccurate alignment results in vibration and excessive wear on the bearings, sleeve
or shaft and wear rings.
Coupling alignment can be checked with dial gauge Indicator also. Alignment should
be performed after the base plate has been properly set and grout has dried
