Xylem IMVIC R01 Model VIC Vertical Industrial Turbine Can Pumps - Manual (Page 9)

Installation – SECTION 3
When pumping unit is installed in a potentially
explosive environment, the instruction after
the symbol must be followed. Personal
injury and/or equipment damage may occur if these
instructions are not followed. If there is any question
regarding these requirements or equipment is to be
modified, please contact a Goulds Water Technology
representative before proceeding.
FOUNDATION AND PIPING
SUB BASE (SOLE PLATE) OR BARREL FLANGE
INSPECTION
Sub base and sole plate are terms in common use to
describe a general class of solid steel plates mounted
in grout (or bolted to steel structures) at the pump-
foundation interface.
1. Remove the sub base from the pump discharge head
or barrel flange, when shipped assembled.
2. Completely clean the underside of the sub base. It is
sometimes necessary to coat the underside of the sub
base with an epoxy primer. (This is available as an
option.)
3. Remove the rust preventative solution from the
machined topside with an appropriate solution.
SITE WITH CONCRETE FOUNDATION
1. A pump should have adequate space for operation,
maintenance, and inspection.
2. Sub base mounted pumps are normally grouted
on a concrete foundation, which has been poured
on a solid footing. The foundation must be able to
absorb any vibration and to form a permanent, rigid
support for the pumping unit.
3. The foundation must be of adequate strength to
support the complete weight of the pump, plus the
weight of the liquid passing through it. A typical
installation will have bolts with a pipe sleeve 2 ½
times the bolt diameter embedded in the concrete.
Figure 3
Bolts should be sized and located in accordance
with the dimensions given on the Certified Pump
Outline Drawing, if provided. The pipe sleeve
allows movement for the final positioning of the
foundation bolts to conform to the holes in the sub
base flange. See Figure 3.
All equipment being installed must be properly
grounded to prevent unexpected static electrical
discharge. If not, a static electric discharge may
occur when the pump is drained and disassembled for
maintenance purpose.
4. Remove water and/or debris from anchor bolt holes/
sleeves prior to grouting. If the sleeve type bolts are
being used, fill the sleeves with packing or rags to
prevent grout from entering.
5. Carefully lower the sub base onto the foundation
bolts. Hand tighten the nuts.
6. Leveling the sub base may be done by several
methods. Two common methods are:
A. Using leveling wedges. This is shown in Figure 4.
B. Leveling nuts on the anchor bolts.
Regardless of the method, a machinist level must be
used for leveling.
NOTE: When using a machinist level, it is important
that the surface being leveled is free of all
contaminants, such as dust, to ensure an
accurate reading.
7. Level the sub base in two directions at 90º on the
machined surface. The levelness tolerance is 0.005
inches per foot for commercial, and 0.001 inches
per foot for API.

SUB BASE OR BARREL FLANGE GROUTING
1. Inspect foundation for dust, dirt, oil, chips, water,
etc. and remove any contaminants. Do not use oil-
based cleaners as grout will not bond to it. Refer to
grout manufacturer’s instructions.
2. Build dam around foundation (See Figure 4).
Thoroughly wet foundation.
