When mounting Gusher’s style ‘CBM’ (base mounted) the
complete unit is lowered into position, being sure the lifting
straps are NOT attached to pump or motor, while align-
ing foundation bolts with mounting holes in base. Locate
leveling wedges as close to foundation bolts as possible
(Fig. 2), adjust unit to desired position, plumb and level
pump suction and discharge with leveling wedges, snug
foundation bolts down hand tight - DO NOT TIGHTEN at
this point.
COUPLING ALIGNMENT
- Must be checked before
and after start-up. Check parallel alignment by placing a
straight edge across the two coupling flanges and mea-
sure the offset at various points around the periphery of
the coupling. DO NOT rotate the coupling.
If offset ex-
ceeds .010” re-align the coupling. See Fig. 3.
Check angular alignment with micrometer or caliper.
Measure from the outside of the one flange to the outside
of the other flange at intervals around the periphery of
the coupling, DO NOT rotate the coupling. The difference
between the maximum and minimum must not exceed
.010”. If a correction is necessary, be sure to recheck par-
allel alignment. See Fig. 4.
GROUTING
Build a form around the base as illustrated
in Fig. 5. Pour grout into form being sure it flows under
the base. Fill to within
3
/
4
” to 1” of bottom of base. Allow
to set 48 hours, recheck coupling alignment, make any
adjustment that may be necessary and tighten founda-
tion bolts securely.
