SVCN 7 INSTALLATION, OPERATION, & MAINTENANCE
Prepare sufficient steel blocks of at least 1 in. (25 mm) thickness to be placed below each baseplate
jacking screw furnished with the baseplate. The purpose of the plate is to spread the load of the screw
without crushing the concrete below, and to provide a minimum of 1 in. (25 mm) grouting space
below the baseplate.
Before leveling the baseplate, loosen the pump hold down bolts to eliminate any baseplate distortion.
The baseplate may be leveled using either the installed jacking screws, or using shims, or wedges as
illustrated in Figure 2-4 below.
Figure 2-4 Leveling Baseplate With Wedges
Level the baseplate by using a machinist’s level on the machined surfaces of the pump and driver
pads. Adjust the baseplate level by adjusting the leveling screws, or by adjusting the shim packs
under the baseplate.
To adjust the shim pack thickness, carefully raise the baseplate by using either the baseplate jacking
screws provided or by levering with a suitable pinch bar or by installing a low level hydraulic jack.
Adjust the shim pack thickness and lower the baseplate.
Repeat this procedure in a logical manner at each bolt position until the baseplate is level. The
baseplate must be level within 0.002 in. per ft. (0.17 mm per m).
When the baseplate is level, pull down the foundation bolts so they are snug. This may disturb the
baseplate, so re-check the levels.
CAUTION
Before grouting, perform a rough shaft alignment. Final
alignment will not be possible if this initial shaft alignment
is not satisfactorily completed prior to grouting the
baseplate.
