FIGURE 5 – Stilt Mounted
The foundation -mounted style utilizes grout to
add rigidity to the structure. Because the
ChemBasePlus™ by nature offers excellent
rigidity, the Stilt-mounted style can be
employed without sacrificing on reliability
whatsoever. The Stilt-mounted base offers a
free-standing rigid foundation void of any
additional grouting needs.
The ChemBasePlus™ performs the proper
function of a reliable baseplate foundation for a
pump and motor. Those basic functions are as
follows:
1) To provide adequate rigidity to assure
the pump/motor assembly can be
shipped and installed without damage
and to withstand the operating loads of
the given assembly. The solid
structure of the ChemBasePlus™
offers superior dampening to vibration
associated with the rotating
pump/motor assembly.
2) To provide a flat mounting surface for
the pump and motor assembly. The
ChemBasePlus™ product is designed
to hold under a .005 inch flatness
specification (end-to-end). The
aforementioned flatness specifications
are measured across the diagonal
corners of the baseplate top surface.
These excellent flatness specifications
are achieved by the superior Epoxy
Resin Aggregate Material utilized in
the construction of these baseplates.
3) To allow the end user to perform final
field alignment to their respective
tolerance standards.
4.2 MOTOR MOUNTING SYSTEM
The Goulds ChemBasePlus™ utilizes as
standard the polymer block mounting system.
This system is comprised of corrosion resistant
polymer composite mounting blocks which
have surface flatness to .005”. Motor mounting
blocks incorporate a counterbore / jam nut
feature for secure attachment to the
ChemBasePlus™

Optional Bi-Directional motor adjusters provide
both axial and transverse motor adjustment.
The top mounted adjusters assist with precise
shaft alignment when critical tolerances are
trying to be achieved as they do not disturb
indicator equipment.
4.3 FOUNDATON MOUNTED BASEPLATES
1) The baseplate should be positioned as
close to the liquid supply source as
possible. There should be an
adequate amount of space for
personnel to install, operate and
maintain the pump/motor assembly.
As mentioned above, the end result of
the grouted in baseplate should offer
excellent rigidity and dampen any
vibration associated with the operating
pump/motor assembly.
