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.

4. Remove water and/or debris from anchor bolt holes/
5. Carefully lower the sub base onto the foundation
6. Leveling the sub base may be done by several
Regardless of the method, a machinist level must be
used for leveling.

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.
