NOTICE:
Final tightening of foundation bolts is done after grout has set 48 hours.
Figure 3:
5. Grouting Unit on Foundation:
a) Build wood dam around foundation as shown in Figure 2: Foundation on page 10 . Wet top sur-
face of concrete foundation thoroughly.
b) Pour grout in hole provided in the top of the bedplate. Use of a non-shrink grout is recommend-
ed. The grout should be thin enough to flow out under the bedplate. A mixture of one part Port-
land cement to three parts sharp sand may also be used. Cement grout should not be so thin
that the cement will separate from the sand.
c) The grout should be puddled continuously as it is poured to expel the air and completely fill the
space under the bedplate, to the level of the grout hole in the top of the bedplate.
d) With a trowel, strike along the top of the wood dam to give a neat, finished appearance at this
point.
e) Allow grout to harden at least 48 hours.
2.3 Alignment - initial
Alignment of the pump and driver through the flexible coupling is of extreme importance for trouble-free
mechanical operation.
If the driver was mounted at the factory, the unit was in alignment before it left our assembly department.
However, in transit and subsequent handling, this factory alignment was probably destroyed; and, it is
now necessary to reestablish the alignment. As directed in Foundation (Step 4, Mounting unit on founda-
tion), only approximate alignment was obtained by wedging under bedplate before grouting.
The following are suggested steps to establish the initial alignment of the pumping unit.
NOTICE:
This is an initial alignment. The final alignment is done after the unit has been run under actual
operating conditions. The final alignment procedure is outlined in
4.3 Alignment - final on page
21 and must be followed.
1. Be sure coupling halves are disconnected as previously instructed, except spider-insert type.
2. Tighten foundation bolts.
