CAUTION
• Avoid distortions when finally tightening the bolts.
• The nuts of the foot fastening must be loosened so far
that the washers can be moved by light hammer
blows.
5.6 Grouting the baseplate
Prior to grouting the baseplate, carry out the following
preparatory work:
- Check the dimensions with regard to height and
alignment of flanges.
- Re-adjust baseplate, if necessary.
Ram earth-humid concrete under the baseplate or add
shrinkage-free grout until the entire space under the
baseplate is filled. Grouting should be a continuous
process so as to ensure that no air pockets form under the
baseplate.
When the grout is set re-tighten the foundation bolts and
re-check the alignment of the coupling.
5.7 Pump installation in the piping system
CAUTION
• The pipework forces and moments acting on the pump
nozzles must not exceed the permissible pump nozzle
loads.
• The pump must not be used to clean the pipework
with chemicals.
- Remove the protection covers from the pump flanges
and the auxiliary pipeline connections.
- Insert the flange gaskets.
- Connect the suction or feed line.
- Connect the discharge line.
5.8 Hydrostatic test
• If the piping system is to undergo a hydrostatic
pressure test, the pump must be excluded from such
testing.
5.9 Cleaning, flushing and pickling of the
pipework
When the pipework is cleaned, flushed or pickled, the
pump must be excluded.
