Leveling mounted on a soleplate and the soleplate of Vertical Turbine Pumps is grouted

Some Vertical Turbine Pumps are mounted on a separate plate known as soleplate [23]. In such cases, the level shall be set with a master level or a precision machinist’s level. The mounting surface needs to be leveled to within 0.025 mm per 0.31 m (0.001 in. per one ft).

The level should not exceed 0.125 mm (0.005 in.) elevation difference taken on any two points on the individual soleplate. Accurate shimming and grouting of the soleplate is very important. Record the leveling data for future reference. Grout the soleplate and allow to set at least 72~80 hours (cure as required) before the pump is lowered into the pit. Align the discharge head boltholes with the anchor bolts [372]. Check and adjust the Vertical Turbine Pump level to within 0.025 mm/0.31 m (0.001 in./ft) with respect to the soleplate and torque the nuts [373] to the required level.
