2) Using the recommended slinging
procedures shown in Figures 2 and 3,
hoist the ChemBasePlus™ unit off its
shipping pallet.
3) Lower the ChemBasePlus™ into
position over the foundation. Proceed
to engage the anchor bolts in the four
holes provided. As seen in Figure 7,
protective sleeves should be placed
over the anchor bolts to prevent grout
adhesion to the bolts.

4) The baseplate assembly should be
properly leveled. It is suggested to
utilize the pump suction and discharge
flanges as reference points for leveling
purposes. If the ChemBasePlus™ is
equipped with the recommended
optional leveling screw inserts, install
the leveling screws and thread them
far enough to provide the desired
grouting clearance underneath. Apply
wax to screws to allow for their
eventual removal.
5) If the ChemBasePlus™ is not
equipped with leveling screws, shim
under the baseplate to bring the
discharge flange into proper level.
Never stress the baseplate under any
condition to bring the assembly into
the desired level. Hold off bolting the
pump’s flanges until the baseplate is
completely installed. A proper
practice is to shim under all baseplate
anchor bolt locations. Apply wax to
shims to allow for their eventual
removal.
6) Install the flat washers and nuts to the
anchor bolts and snug them down but
do not torque them at this point.
7) Alignment should now be done in
accordance with procedures identified
in Appendix IV.
8) The baseplate should now be properly
grouted. Grout the baseplate in
accordance with the grout
manufacturer’s recommended
procedures. Mask off areas not
intended to be grouted. Good
procedure is to utilize a non-shrinking
grout material. Pour or trowel the
grout into the desired area until the
proper level is reached. Immediately
wipe away any spills as this must be
done before the grout sets. Allow at
least two days for the grout to fully
cure.
9) Check for voids after the grout has
properly cured. Remove the forms
and withdraw the leveling screws or
shims used for leveling. Remove the
masking from all surfaces.
10) Fill the leveling screw holes (if
provided) with a flexible sealer.
11) Lubricate the anchor bolt threads and
tighten the nuts to the following torque
values: ½” bolt – 22 lb/ft or ¾” – 65
lb/ft.
12) Connect piping to the flanges of the
pump. Assure that no adverse piping
loads are transmitted to the pump
flanges. Perform a final alignment
check for verification that there are no
significant piping loads.
13) Final alignment of the pump/motor
assembly should now be brought into
the tolerances as specified in
Appendix IV.
14) It is possible that a realignment may
be deemed necessary should the
temperature of the process conditions
cause suspect thermal expansion of
the piping.
