practice is to confirm in our shop that the pump
assembly can be accurately aligned. Before
shipment, the factory verifies that there is
enough horizontal movement capability at the
motor to obtain a “perfect” final alignment when
the installer puts the baseplate assembly into
its original, top levelled, unstressed condition.
4.3.3 Stilt and spring mounted baseplates
Flowserve offers stilt and spring mounted
baseplates. (See Figure 4-2 for stilt mounted
option.) The low vibration levels of TB-MA
G™
pumps allow the use of these baseplates - provided
they are of a rigid design. The baseplate is set on
a flat surface with no tie down bolts or other means
of anchoring it to the floor.
General instructions for assembling these
baseplates are given below. For dimensional
information, please refer to the appropriate
Flowserve “Sales print.”
4.3.3.1 Stilt mounted baseplate assembly
instructions
Refer to Figure 4-3.
a)
Raise or block up baseplate/pump above the
floor to allow for the assembly of the stilts.
b) Predetermine or measure the approximate
desired height for the baseplate above the
floor.
c) Set the bottom nuts [2] above the stilt bolt
head [1] to the desired height.
d) Assemble lock washer [3] down over the stilt
bolt.
e) Assemble the stilt bolt up through hole in the
bottom plate and hold in place.
f) Assemble the lock washer [3] and nut [2] on
the stilt bolt. Tighten the nut down on the lock
washer.
g) After all four stilts have been assembled,
position the baseplate in place, over the floor
cups [4] under each stilt location, and lower
the baseplate to the floor.
h) Level and make final height adjustments to the
suction and discharge pipe by first loosening
the top nuts and turning the bottom nuts to
raise or lower the baseplate.
i) Tighten the top and bottom nuts at the lock
washer [3] first then tighten the other nuts.
j) It should be noted that the connecting
pipelines must be individually supported, and
that the stilt mounted baseplate is not intended
to support total static pipe load.

4.3.3.2 Stilt/spring mounted baseplate
assembly instructions
Refer to Figure 4-4.
a)
Raise or block up baseplate/pump above the
floor to allow for the assembly of the stilts.
b) Set the bottom nuts [4] above the stilt bolt head
[1]. This allows for 51 mm (2 in.) upward
movement for the final height adjustment of the
suction/discharge flange.
c) Assemble the lock washer [6] flat washer [5]
and bottom spring/cup assembly [2] down over
the stilt bolt [1].
d) Assemble the stilt bolt/bottom spring up
through hole in the bottom plate and hold in
place.
e) Assemble top spring/cup assembly [3] down
over stilt bolt.
f) Assemble flat washer [5], lock washer [6] and
nuts [4] on the stilt bolt.
g) Tighten down top nuts, compressing the top
spring approximately 13 mm (0.5 in.).
Additional compression may be required to
stabilize the baseplate.
h) After all four stilts have been assembled,
position the baseplate in place, over the floor
cups [7] under each stilt location, and lower
the baseplate down to the floor.
i) Level and make final height adjustments to the
suction and discharge pipe by first loosening
the top nuts, and turning the bottom nuts to
raise or lower the baseplate.
j) Recompress the top spring to the compression
established in step g, and lock the nuts in
place.
k) It should be noted that the connecting
pipelines must be individually supported, and
that the spring mounted baseplate is not
intended to support total static pipe loads.
