vertical alignment, and by moving the pump for
horizontal alignment.
e) If the fasteners are centered, then the baseplate
may be twisted. Slightly adjust (one turn of the
adjusting nut) the stilts at the driver end of the
baseplate and check for alignment to the above
tolerances. Repeat as necessary while
maintaining a level condition as measured from
the pump discharge flange.
f) Lock the stilt adjusters.
The remaining steps are as listed for new grouted
baseplates.

a) The pump foundation should be located as close
to the source of the fluid to be pumped as
practical.
b) There should be adequate space for workers to
install, operate, and maintain the pump. The
foundation should be sufficient to absorb any
vibration and should provide a rigid support for
the pump and motor.
c) Recommended mass of a concrete foundation
should be three times that of the pump, motor
and base. Refer to figure 4-5.
Foundation bolts are imbedded in the
concrete inside a sleeve to allow some
movement of the bolt.

d) Level the pump baseplate assembly. If the
baseplate has machined coplanar mounting
surfaces, these machined surfaces are to be
referenced when leveling the baseplate. This
may require that the pump and motor be removed
from the baseplate in order to reference the
machined faces. If the baseplate is without
machined coplanar mounting surfaces, the pump
and motor are to be left on the baseplate. The
proper surfaces to reference when leveling the
pump baseplate assembly are the pump suction
and discharge flanges. DO NOT stress the
baseplate.
e) Do not bolt the suction or discharge flanges of the
pump to the piping until the baseplate foundation
is completely installed. If equipped, use leveling
jackscrews to level the baseplate. If jackscrews
are not provided, shims and wedges should be
used. (See Figure 4-5.) Check for levelness in
both the longitudinal and lateral directions.
Shims should be placed at all base anchor bolt
locations, and in the middle edge of the base if
the base is more than 1.5 m (5 ft.) long. Do not
rely on the bottom of the baseplate to be flat.
Standard baseplate bottoms are not machined,
and it is not likely that the field mounting surface
is flat.
f) After leveling the baseplate, tighten the anchor
bolts. If shims were used, make sure that the
baseplate was shimmed near each anchor bolt
before tightening. Failure to do this may result in
a twist of the baseplate, which could make it
impossible to obtain final alignment.
g) Check the level of the baseplate to make sure
that tightening the anchor bolts did not disturb the
level of the baseplate. If the anchor bolts did
change the level, adjust the jackscrews or shims
as needed to level the baseplate.
h) Continue adjusting the jackscrews or shims and
tightening the anchor bolts until the baseplate is
level.
i) Check initial alignment. If the pump and motor
were removed from the baseplate proceed with
step j) first, then the pump and motor should be
reinstalled onto the baseplate using Flowserve’s
factory preliminary alignment procedure as
described in section 4.5, and then continue with
the following. As described above, pumps are
given a preliminary alignment at the factory. This
preliminary alignment is done in a way that ensures
that, if the installer duplicates the factory conditions,
there will be sufficient clearance between the motor
hold down bolts and motor foot holes to move the
motor into final alignment. If the pump and motor
were properly reinstalled to the baseplate or if they
were not removed from the baseplate and there has
been no transit damage, and also if the above steps
where done properly, the pump and driver should
be within 0.38 mm (0.015 in.) FIM (Full Indicator
Movement) parallel, and 0.0025 mm/mm (0.0025
in./in.) FIM angular. If this is not the case, first
check to see if the driver mounting fasteners are
centered in the driver feet holes. If not, re-center
the fasteners and perform a preliminary alignment
to the above tolerances by shimming under the
motor for vertical alignment, and by moving the
pump for horizontal alignment.
