assembled to the pump and lined up as detailed in
section 4.5.2 Alignment method.
4.3 Foundation
The foundation may consist of any
material that will afford permanent, rigid support to the
full area of the pump or driver supporting member. It
should be of sufficient size and mass to absorb
expected strains and shocks that may be encountered
in service. Concrete foundations built on solid ground
are desirable.
The purpose of foundation bolts is to anchor the pump
unit securely to the foundation such that the foundation
and pump assembly become a single structural unit.
High strength steel foundation bolts (SAE Gr. 5 or
better) of the specified diameter should be located
according to the elevation drawing provided. Each bolt
should be surrounded by a pipe sleeve two or three
times the diameter of the bolt (see Figure 1). The
sleeves should be securely anchored and designed to
allow the bolts to be adjusted to conform to the holes
in the baseplate. The bolts should be sufficiently long
to allow for wedges or shims or levelling nuts under the
baseplate, and a washer, heavy hex nut and hex jam
nut for retention. Since baseplate levelling is
performed after the foundation has cured, it is best to
use extra-long bolts which can be shortened after the
installation is complete.
Figure 1 – Grout Installation
4.4 Baseplate installation
Position the baseplate and pump next to the
foundation
and clean the foundation surface
thoroughly. Remove the rag packing from the pipe
sleeves and place wedges or shims as close to the
foundation bolts as possible. These may be omitted if
a jacking nut on the foundation anchor bolts is
preferred for levelling. Initial levelling should be within
0.75 mm (0.030 in.).
Remove the flange covers and check inside the pump
nozzles for cleanliness. Kerosene is recommended as
the best solvent for removing factory applied rust
preventative. Ensure that all traces of rust preventative
are removed from the discharge and suction flange
faces, the exposed shafting and all coupling surfaces.
Flush the pump internals of any rust preventative
applied for long term storage.
Lift the baseplate assembly, remove the shipping skids
and clean the underside of the baseplate. Position the
baseplate over the foundation and lower the unit over
the foundation bolts and onto the wedges, shims or
jacking nuts.
With the aid of a machinist's level, adjust the wedges,
shims or jacking nuts to level the pump and driver
mounting pads in each direction. Check to ensure that
the suction and discharge flanges are plumb, level,
and at the correct elevation. It is normal practice to set
the mounting pads slightly low in order to permit
lowering of units which may be required to suit future
piping or minor changes. Place washers over the
foundation bolts and install nuts. Tighten finger tight
only. Check that the rotor turns freely by hand.
Note: Grout shall not be poured until an initial
preliminary alignment of the pump and driver has
been performed.
4.5 Initial alignment
4.5.1 Thermal expansion
The pump and motor will normally have
to be aligned at ambient temperature and should be
corrected to allow for thermal expansion at operating
temperature. In pump installations involving high liquid
temperatures, the unit should be run at the actual
operating temperature, shut down and the alignment
re-checked and re-adjusted as deemed necessary
immediately.
4.5.2 Alignment methods
Ensure pump and driver are isolated
electrically and the half couplings are disconnected .
The alignment MUST be checked.
Although the pump will have been aligned at the
factory it is most likely that this alignment will have
been disturbed during transportation or handling. If
necessary, align the motor to the pump, not the pump
to the motor.
