3.2.5 Building up the foundation
The foundation procedure has three steps:
1. pouring of foundation
2. shimming of base frame
3. grouting.
Pouring of foundation
We recommend the following procedure to ensure a
good foundation:
1. Pour the foundation without interruptions to within
19-32 mm of the final level. Use vibrators to
ensure that the concrete is evenly distributed. The
top surface must be well scored and grooved
before the concrete sets. This provides a bonding
surface for the grout.
2. Embed anchor bolts in the concrete as shown in
figures below. Allow enough bolt length to reach
through grout, shims, lower base frame, nuts and
washers.

TM074091
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.
