Goulds Pumps 3498 - IOM - Manual (Page 24)

SETTING THE BASEPLATE (BEFORE PIPING)
NOTE: This procedure assumes that a concrete
foundation has been prepared with anchor or hold
down bolts extending up ready to receive unit. It must
be understood that pump and motor have been
mounted and rough aligned at the factory. If motor is
to be field mounted, consult factory for
recommendations. Goulds Pumps cannot assume
responsibility for final alignment.
1. Use blocks and shims under base for support at anchor
bolts and midway between bolts, to position base
approximately 1" above the concrete foundation with
studs extending through holes in the baseplate.
2. By adding or removing shims under the base, level and
plumb the pump shaft and flanges. The baseplate does
not have to be level.
3. Draw anchor nuts tight against base, and observe pump and
motor shafts or coupling hubs for alignment. (Temporarily
remove coupling guard for checking alignment.)
4. If alignment needs improvement, add shims or wedges at
appropriate positions under base so that retightening of
anchor nuts will shift shafts into closer alignment. Repeat
this procedure until a reasonable alignment is reached.
NOTE: Reasonable alignment is defined as that which
pump contractor and the accepting facility (final
operator) mutually agree upon. Final alignment
procedures are covered under “Alignment Procedure.”
GROUTING PROCEDURE
Grout compensates for uneven foundation, distributes
weight of unit, and prevents shifting. Use an approved,
non-shrinking grout (such as Embeco 636 by Master
Builders, Cleveland, Ohio or equivalent), as follows, after
setting and leveling unit. (See Fig. 8).
1. Build strong form around the foundation to contain
grout.
2. Soak top of concrete foundation thoroughly, then
remove surface water.
3. Baseplate should be completely filled with grout and if
necessary, temporarily use air relief tubing or drill vent
holes to remove trapped air.
4. After the grout has thoroughly hardened, check the
foundation bolts and tighten if necessary.
5. Check the alignment after the foundation bolts are
tightened.
6. Approximately 14 days after the grout has been poured
or when the grout has thoroughly dried, apply an oil
base paint to the exposed edges of the grout to prevent
air and moisture from coming in contact with the
grout.
