Shimming of base frame
Shimming of base frame and levelling of pump
1. Lift or jack up the base frame to the final level
19-32 mm above the concrete foundation, and
support the base frame by means of blocks and
shims, both at the anchor bolts and midway
between bolts. See figure above .
2. Level the base frame by adding or removing
shims under the base frame. See figure above.
3. Tighten the anchor bolt nuts against the base
frame. Make sure the pipes can be aligned to the
pump flanges without putting strain on the pipes
or flanges.

Grouting
Grouting compensates for uneven foundation,
distributes the weight of the unit, dampens vibrations
and prevents shifting. Use an approved, non-
shrinking grout. If you have questions or doubts about
the grouting, consult an expert on grouting.
Proceed as follows:
1. Build a strong formwork around the foundation to
contain the grout.
2. Soak the top of the concrete foundation
thoroughly, then remove surface water.
3. Fill the formwork with grout up to the bottom edge
of the base frame. See figure below. Allow the
grout to dry thoroughly before attaching the pipe
to the pump. 24 hours is sufficient time with
approved grouting procedure.
4. When the grout has thoroughly hardened, check
the anchor bolt nuts and tighten them if
necessary.
5. Approximately two weeks after the grout has been
poured, or when the grout has thoroughly dried,
apply an oil-based paint to the exposed edges of
the grout to prevent air and moisture from getting
in contact with the grout.
