9. Installation
Our pumps should be installed, leveled and aligned by skilled
and trained personnel. When this service is done incorrectly,
it will originate operational troubles, premature wear and
damage beyond repair.
9.1 Base grouting
Place the foundation bolts in the holes or slots of the
foundation block according to boring design as shown on the
foundation drawing.
Between the base and the foundation block and beside the
foundation bolts, metallic chocks of the same height should
be fixed with grout together with the foundation bolts, to
serve as support for the base.
In order to achieve a perfect adherence to the grout, the
chock blocks and foundation bolts should be free of any
grease or oil residues. After the grout set is completed, place
the base on the foundation block (non-shrinking mortar is
highly recommended). Please see Fig. 4.
Fig. 4 – Base grouting
9.2 Base leveling
Check if the base plate is equally resting on its chock blocks,
if it is correctly set, place and tighten uniformly the nuts on
the foundation bolts. With the help of a precision level, check
the leveling of the base longitudinally and transversally.
If the base plate is out of level, loosen the foundation bolt
nuts and insert shims, as necessary, between the metallic
chock block and the base, in order to correct the leveling.
Please see fig.5.

Note:
After leveling the base and before concrete fulfill, the
motor-pump set must be pre-aligned according to the
instructions of item 9.4.
9.3 Grouting
In order to get a good, vibration-free operation, the pump
base plate must be filled with grout.
Grout should be made of specific compounds available in the
civil construction market, which prevent shrinkage through
grout setting process as well as full base filling and does not
allow blanks or gaps. Please see Fig. 6a
Fig. 6a-Base fulfill with grout
9.3.1 Execution with adjustment screws
When adjustment screws are used under motor side
surrounding areas should be free of concrete. Protecting
tubes should be used, in order permit future adjustments to
align the equipments. See fig.6b.
