Goulds Pumps ANSI FAMILY IOM (ATEX Compliant) - Manual (Page 29)

After satisfactory slinging has been achieved, the
Polyshield
® ANSI Combo may be hoisted onto its
foundation. Take care not to bump the unit against
fixed objects or induce any unnecessary shock loads.
Lower the unit slowly over the foundation using care
to center the unit over the rebar cage. Place shim
packs or wedges under the Polyshield
®
unit at a
minimum of eight total (or four [4] locations on each
side) to allow for the removal of the slings. Twelve
(12) total shim locations (or six [6] shim locations each
side) are required for Polyshield
®
units exceeding 6
feet in length.
Installation
General Description of the Polyshield
®
ANSI
Combo
The Polyshield
®
ANSI Combo is a solid, polymer
concrete foundation and baseplate shell that is
manufactured in versions that conform to
accommodate ASME/ANSI B73.1 pumps.
Polyshield ® ANSI Combo units are manufactured in
five primary sizes with integral catch basins and
removable motor mounting blocks.
Metallic thread inserts are provided in the mounting
surface for the particular combination of pump and
motor that the Combo is intended. The metallic thread
inserts on the pump end are available in 316SS (18.8
CrNi stainless steel), Alloy 20 (A744, CN-7M) and
Hastelloy C 276 (A494, CW-6M). Multiple motor
insert patterns are also available to accommodate
more than one NEMA frame size. The standard
thread insert material for the motor end is 316SS
(18.8 CrNi stainless steel).
Optional alloy pads are available instead of metallic
inserts for requirements that call for 0.002”/ft. and or
process temperatures between 301° F and 500° F.
Polyadjust Motor Block Adjuster System
The Polyshield
®
ANSI Combo utilizes as standard the
unique Polyshield
®
Polyadjust motor mounting system
(Fig. B). This system is comprised of a one-piece
polymer concrete motor mounting block having
surface flatness and parallelism equivalent to machine
steel blocks. The Polyadjust motor mounting block
system incorporates the Polyloc Transverse Jack Bolt
system. The Polyloc system provides transverse
motor adjustment. The side-mounted adjusters allow
for shaft alignment to critical tolerances with minimal
disturbance of indicators. The adjusters make contact
with a solid motor mounting block not the foot of the
motor.

Installation Procedures (NEW CONSTRUCTION)
1. Remove laitance and form grease and oil from
area where the Polyshield
® ANSI Combo will be
located using mechanical means, abrasive
blasting, or water blasting. Remove any loose
debris including fins, aggregate, or any protruding
objects around the perimeter of the area where
the Polyshield ANSI Combo will rest.
2. Measure the outside dimensions of the
Polyshield
® ANSI Combo and subtract 8” from
both the width and length to determine the rebar
maximum dimension, thus providing clearance
from the side of the walls of the ANSI Combo.
3. Drill holes in the existing slab a minimum of four
inches deep for doweling in the vertical rebar rods
allowing a minimum of one inch clearance from
the top of the interior of the Polyshield
®
ANSI
Combo. Space the rebar rods of 12” centers.
Remove dust and debris from dowel holes and fill
with epoxy adhesive for anchoring the rebar.
4. Allow the epoxy adhesive to cure, and then install
horizontal rebar rods, tying in place with wire.
5. Place the Polyshield ® ANSI Combo over the rebar
cage, making adjustments for proper elevation,
orientation relative to piping centerlines. A
qualified millwright should field verify proper
position of the pump mounting pads relative to the
centerline of the suction piping. Appropriate
shims may be placed along the bottom edge of
the Polyshield
® ANSI Combo to aid in leveling.
Place shim packs or wedges under the
Polyshield
®
unit at a minimum of eight total (or
four [4] locations on each side) to allow for the
removal of the slings and metal lifting straps from
each end. A minimum of twelve (12) total shim
locations (or six [6] shim locations each side) are
recommended for Polyshield
®
units exceeding
7 feet in length.
