3. Set baseplate with pump on shims and/or leveling screws, bending anchor bolts as necessary
to align them with holes in baseplate.
NOTE
Pump feet and their holddown bolts are inaccessible with
lagging in place.
4. Remove insulation covers, if installed, from top half of pump.
5. To eliminate any torsional affect that the pump might exert on baseplate, loosen holddown
bolts at each pump foot.
6. Thoroughly clean exposed edges of pad at each pump foot and surface of all mounting pads.
7. Level and anchor baseplate according to instructions that apply to your circumstance.
a. First method (using optical alignment equipment), level baseplate using optical alignment
equipment on shims and/or leveling screws within nominal leveling gradient of 0.001
inch per 12 inches (0.03 mm per 305 mm). Then tighten down anchor nuts and recheck
for nominal gradient. If baseplate is not level, loosen anchor nuts, relevel it, retighten
nuts, and recheck for nominal gradient. Continue this process until the baseplate is
anchored and level.
b. Second method (using machinist level) proceed as follows:
1). Determine high end of baseplate. Then start leveling across pads on high end by
adding or removing shims at, or adjusting leveling screws at, anchor bolts adjacent to
the pad that you are leveling. For example, when leveling driver pads A and B in
crosswise direction, level at anchor points 1 and 5 (see BASEPLATE TOP VIEW
figure), with level positioned as shown in LEVELING DRIVER END CROSSWISE
figure. Continue leveling until baseplate is level in crosswise direction at places
illustrated by LEVELING PUMP END CROSSWISE and LEVELING DRIVER
END CROSSWISE figures; further, verify level of all mounting pads on your
baseplate across their middles and ends, particularly those ends nearest pump.
2). Level both sides of baseplate in lengthwise direction by adding or removing shims at,
or adjusting leveling screws at, anchor bolts adjacent to pad that you are leveling. For
example, if leveling driver pad A, level at anchor points 2, 3 and 4 (see BASEPLATE
TOP VIEW figure), with level positioned as shown in LEVELING DRIVER END
LENGTHWISE figure. Continue leveling until all pads on both sides of your
baseplate are level in lengthwise direction at places shown in LEVELING DRIVER
END LENGTHWISE and LEVELING PUMP END LENGTHWISE figures.
