Installation with isolation base
When using an isolation base, flexible piping should be used on both suction and
discharge sides to reduce the strain on the flanges.
Install the pump, driver, and coupling
Perform these steps only if the unit was not installed at the factory.
1. Mount and fasten the pump on the baseplate. Use applicable bolts.
2. Mount the driver on the baseplate. Use applicable bolts and hand tighten.
3. Install the coupling.
See the installation instructions from the coupling manufacturer.
Level the base on a concrete foundation
Before leveling and grouting the base, perform an initial alignment. See Pump-to-driver
alignment.
1. Place the pump on its concrete foundation.
2. Place 1.00 in./(25.40 mm) thick steel shims or wedges on both sides of each anchor
bolt in order to support the pump .
This also provides a means of leveling the base.

Grout the baseplate
Required equipment:
• Cleaners: Do not use an oil-based cleaner because the grout will not bond to it. See
the instructions provided by the grout manufacturer.
• Grout: Non-shrink grout is required.
1. Clean all the areas of the baseplate that will come into contact with the grout.
2. Build a dam around the foundation.
3. Thoroughly wet the foundation that will come into contact with the grout.
4. Pour grout into the baseplate up to top of the base rails.
