Leveling of pumps with the suction barrel 4.3.3
(also referred as “Can” VTPs)
The suction barrel [315] is first lowered into the pit and
aligned with the anchor bolts [372]. The suction barrel
flange is leveled by using a master level or a precision
machinist’s level. Levels should be taken on the
equipment mounting surfaces. The suction barrel
flange mounting surface needs to be leveled to within
0.16 mm/m (0.002 in./ft) using shims and grouted.
Allow the grout to set for at least 72~80 hours before
the pump is installed. Check the barrel mounting
surface level after the grout is set and then proceed
with the pump installation. Lower the pump assembly
into the pit and align the discharge head flange bolt
holes to the anchor bolts [372].
Check and adjust the pump level with respect to the
barrel flange to within 0.16 mm/m (0.002 in./ft) and
final torque the nuts [373]. The leveling data to be
recorded for future reference.

Leveling of pumps with suction barrel 4.3.4
mounted on a soleplate
The soleplate [23] is installed on the foundation and
aligned with the anchor bolts [372]. Level the
soleplate with the help of a machinist’s level to within
0.16 mm/m (0.002 in./ft). Tighten the nuts [373] and
grout. Cure and allow grout to set for 72~80 hours.
Lower the suction barrel into the pit and level again
with respect to the soleplate [23] to within 0.16 mm/m
(0.002 in./ft). The level should not exceed 0.125 mm
(0.005 in.) elevation difference taken on any two
points on the soleplate. The pump [101] is now
lowered into the suction barrel and installed. Make
sure that the discharge head flange is still in level
within 0.16 mm/m (0.002 in./ft) with respect to the
suction barrel [315].

Grouting 4.4
Where applicable, grout in the foundation bolts.
After adding pipe work connections and re-checking
the coupling alignment, the mounting plate/soleplate
should then be grouted in accordance with good
engineering practice. If in any doubt, please contact
Flowserve service center for advice.
Grouting provides solid contact between the pump
unit and foundation that prevents lateral movement of
running equipment and dampens resonant vibrations.
Care should be taken to ensure maximum surface
contact with grout between the pump base, sole
plate, suction can and foundation (no voids).
Foundation bolts should only be fully
tightened after the grout has been cured.
