Foundation bolts are located according to the bolt hole
dimensions shown on the installation drawing. Bolt
size is based on hole size, they should be 1/8” to ¼”
under the sub-base hole size. For information on
spring mounted sub-bases, see the following section
under spring mounted bases.
SUB-BASE INSTALLATIONS
GROUTED BASE
When the unit is received with the pump and driver
mounted to the sub-base, it should be placed on the
foundation and the coupling halves or V-belts
disconnected (Fig. 6). The coupling should not be
reconnected until all realignment operations have been
completed. A recommended coupling alignment
procedure is included in the following sections.
1. The sub-base should be supported on rectangular
metal blocks or on metal wedges having a slight
taper. There should be support blocks or wedges
on both sides of each foundation bolt. A gap of
about 3/4" to 1-1/2' should be allowed between the
sub-base and the foundation for grouting (Fig. 7).
2. Adjust the metal supports or wedges until the
shafts of the pump and driver and sub-base are
level. Check the coupling faces, as well as the
suction and discharge flanges of the pump, for
horizontal and vertical position by means of a
level. Check also for any internal rubbing in the
pump. Correct, if necessary, by adjusting the
supports or wedges under the sub-base as
required. In most cases, factory alignment will be
regained by shimming under the sub-base alone.
Provisions must be made to support the discharge
piping independently from the pump to prevent
excessive loads and maintain pump-driver alignment.
3. The sub-base should be level to within .125 in. (3
mm) over the length of the base and .0875 in. (1.5
mm) over the width of the base. Bases anchored
with conventional foundation bolts use shims on
both sides of the anchor bolts to level the base.
The bolts which secure the pump sub-base to the
foundation should be 1/8” - ¼” less in diameter
than the holes in the sub-base (hole size is shown
on the certified installation drawing).
4. Clean outside areas of sub-base that will contact
grout. Do not use oil-based cleaners because
grout will not bond to it. Refer to grout
manufacturer's instructions.
5. Build a dam around foundation and thoroughly wet
the foundation (Fig. 8)
