Provide sufficient space in the foundation to
accommodate the anchor bolts. If necessary,
provide concrete risers.
Usually the pump and its drive are mounted on a
common base plate. If not, individual base plates
underneath each machine foot shall be installed.
Base plates are to be fully grouted.
4.2.1 Setting the base plate for anchoring
a) Clean the foundation surface thoroughly.
b) Put shims on the foundation surface [approx 20-
25 mm (0.79-0.98 in.) thick], one on each side of
the bolt hole (as an alternative, leveling screws
can be used).
c) Lay the base plate and level in both directions
with extra shims. The base plate should be level
to within 0.5 mm per 1 m (0.02 in. per 3.3 ft).
.
d) If anchor bolts have been pre-cast in the
foundation slightly tighten the anchor bolts.
Otherwise let them hang in the foundation holes.
4.3 Grouting
4.3.1 Base plate grouting
a) Prepare the site for grouting. Before grouting
clean the foundation surface thoroughly and
provide external barriers as shown. The base
plate is provided with holes to be filled with the
concrete.

b) Prepare grouting product (concrete, resin) in
accordance with manufacturers' instructions.
c) Use grouting products with anti-shrinking
components.
d) To grout up to the required level. Polish
surfaces. Take necessary precautions to avoid
air bubbles.
e) Lay-down the barrier, break external angles, and
polish the different surfaces.
f) After grout starts to cure, definitively tighten
anchor bolts.
g) Control the alignment such as described as
follows.
4.4 Initial alignment
Before connecting the couplings
verify the motor rotation direction.
4.4.1 Thermal expansion
The pump and motor will normally
have to be aligned at ambient temperature and
should be corrected to allow for thermal expansion
at operating temperature. In pump installations
involving high liquid temperatures, the unit should be
run at the actual operating temperature, shut down
and the alignment checked immediately.
4.4.2 Alignment methods
Ensure pump and driver are isolated
electrically and the half couplings are disconnected.
Ensure that the pump pipework, suction and
discharge, is disconnected.
