Leveling of Canned Vertical Turbine Pumps with the suction barrel (also referred as Canned VTP Pumps)

Leveling of Vertical Turbine Pumps with suction barrel mounted on a soleplate:

soleplate with the help of a machinist’s level to within 0.025 mm/0.31 m (0.001 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 0.025 mm/0.31 m (0.001 in./ft). The level should not exceed 0.125 mm (0.005 in.) elevation difference taken on any two points on the soleplate. The Vertical Turbine Pump [101] is now lowered into the suction barrel and installed. Make sure that the discharge head flange is still in level within 0.025 mm/0.31 m (0.001 in./ft) with respect to the suction barrel [315].

Leveling of Vertical Turbine Pumps with the suction barrel (also referred as Canned VTP Pumps)

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 0.025 mm/0.31 m (0.001 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 Vertical Turbine Pump assembly into the pit and align the discharge head flange bolt holes to the anchor bolts [372].

Check and adjust the Vertical Turbine Pump level with respect to the barrel flange to within 0.025 mm/0.31 m (0.001 in./ft) and final torque the nuts [373]. The leveling data to be recorded for future reference.
