Add or remove shims under the base to level the pump-shaft. The base plate itself does not have to
be level.
Grout base plate in completely and allow grout to dry thoroughly before attaching piping to pump (24
hours is sufficient time with the approved grouting procedure).
The suction and discharge piping should be installed after the pump unit, ensuring that no pipe strain
is placed on either flange and that both pump and pipe flanges are square to each other.
GROUTING PROCEDURE
Grouting compensates for uneven foundations, distributes weight of unit and prevents shifting. Use
an approved, non-shrinking grout as follows, after setting and leveling unit:
Build strong form work around foundation to contain grout.
Soak top of concrete foundation thoroughly, then remove surface water.
Completely fill base plate with grout.
After grout has thoroughly hardened, torque down foundation bolts, then re-check alignment. Flat
plain washers should be used on top of the base plate.
Approximately 14 days after the grout has been poured or when the grout has thoroughly dried, apply
an oil based paint to the exposed faces of the grout to prevent air and moisture from coming into
contact.
2.6.4 INSTALLATION FOR BOX SECTION AND CAST IRON BASE PLATES.
Foundation concrete should be prepared in line with the General recommendations and allowed to
cure for several days. Height should be only slightly below finished to allow for shimming.
Suction piping may be installed in advance and the pump unit positioned and shimmed to align with it,
taking care that no strain is put onto the pump flange. Once positioned, holes can be drilled directly
