NOTE: Allow sufficient space to be able to dismantle
pump without disturbing the pump inlet and
discharge piping.
Select a dry place above the floor level wherever
possible. Take care to prevent pump from freezing
during cold weather when not in operation. Should
the possibility of freezing exist during a shut-down
period, the pump should be completely drained, and
all passages and pockets where liquid might collect
should be blown out with compressed air.
Make sure there is a suitable power source available
for the pump driver. If motor driven, electrical
characteristics should be identical to those shown
on motor data plate.
Foundation
A substantial foundation and footing should be built
to suit local conditions. It should form a rigid support
to maintain alignment.
Vertical Pumps -
Foundation bolts should be sized and
accurately located. Each foundation bolt should be
located in a bushing two diameters larger than the
bolt to allow free movement of the bolt in conforming
to the mounting holes in the pedestal. When vertical
pumps are used with intermediate shafting, the motor
mount baseplate should be securely attached to the
floor or support structure.
Horizontal Pumps -
The foundation should be poured
without interruption to within 1/2 to 1-1/2 inches of
the finished height. The top surface of the foundation
should be well scored and grooved before the
concrete sets; this provides a bonding surface for
the grout. Foundation bolts should be set in concrete
as shown in Figure 8. A 4-inch long tube around
the bolts at the top of the concrete will allow some
flexibility in bolt alignment to match the holes in
the baseplate. Allow enough bolt length for grout,
shims, lower baseplate flange, nuts and washers. The
foundation should be allowed to cure for several days
before the baseplate is shimmed and grouted.
Baseplate setting:
(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 Water Technology
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 base
plate 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.
5. Check to make sure the piping can be aligned to
the pump flanges without placing pipe strain on
either flange.
6. Grout baseplate in completely (See "Grouting
Procedure") and allow grout to dry thoroughly
before attaching piping to pump. (24 hours is
sufficient time with approved grouting 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 Figure 9)
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.
