II. Installation
A. Foundation and Mounting
caution
A hoist or suitable lifting device should
be used to lift the pumping unit. Do NOT
lift the complete unit by the driver, the
pump shafts or the driver lifting eyes.
Hydraulic Institute (HI) recommends a
foundation capable of absorbing vibration at
least five times the weight of the pumping unit
and to form a permanent, rigid support for the
base plate. Consequently, maintaining the
alignment is important for a flexible coupled unit.
Refer to Figure 5 and Figure 6 illustrating
alignment. A concrete foundation on a solid
base is recommended. Use foundation bolts of
the proper size embedded into the concrete. A
pipe sleeve larger in diameter than the bolt
should be used. This allows movement for final
positioning of the bolts. Refer to Figure 3,
Grouting and Foundation Bolting.
As soon as the pump and driver, mounted on a
base plate, is placed on the foundation, remove
the coupling guard and disconnect coupling
halves. Reconnect the coupling after alignment
operations have been completed. The base
plate should be supported on either rectangular
metal blocks with shims or on metal wedges
having a small taper. The support pieces should
be placed close to the foundation bolts. Refer to
Figure 4, Unit Leveling. Place supports directly
under the part of the base plate, which carries
the greatest weight. Space the supports closely
enough to provide uniform support of the base
plate. Adjust the metal supports or wedges until
the pump and driver shafts are level. Check
coupling faces, as well as, suction and
discharge flanges of the pump for horizontal or
vertical positioning by means of a level. Make
corrections, as necessary, by adjusting the
supports or wedges under the base plate.
B. Grouting
After the pumping unit has been leveled and the
alignment is correct, grout the unit to the
foundation using a high-grade, non-shrinking
grout. Proceed grouting using the following
procedure:
1. Lightly tighten foundation bolts evenly
but not fully. Refer to Figure 3, Grouting
and Foundation Bolting.
2. Build a wooden dam around the base
plate to retain the grout.
3. Pour grout through grouting holes
provided in base plate. This should be
done until the entire space under base
plate is filled. While filling the holes,
make sure there are no voids or air
pockets.
4. Insert a stiff wire through the grouting
holes to work the grout and release any
voids or air pockets.
5. After grout has hardened (usually 48
hours), remove the dam and shims or
wedges under the base plate, if desired.
Fill remaining holes by the shims with
grout.
6. Tighten foundation bolts loosely. Allow
the grout to fully cure before firmly
tightening the foundation bolts.
