Installing grout
After the base plate is at the correct location and leveled with a
precision level, grout the base plate to the foundation. Grout
compensates for unevenness in the foundation and base plate and
minimizes vibrations levels during operations. Also grout prevents
the unit from shifting after mounting and alignment.

Foundation bolt location, anchorage mount and leveling
Use only non-shrinking grout for grouting the base plate to
the foundation. Do not fully tighten the foundation bolts
until the grout cures (usually 48 to 72 hours).
1.
Prepare the foundation surface according to the grout
manufacturer's recommendations.
2.
Locate the foundation bolts by the use of a template frame and
provide anchorage. See the outline drawings furnished with
each pump for the exact location of the foundation bolts.
3.
Build a dam on the foundation, enclosing an area around the
base plate that includes all alignment wedges. Allow for a grout
thickness of 0.75 to 1.50 in (19 to 38 mm).
4.
Pour the grout through the holes provided in the base plate or
through open ends of steel channel base plates. While pouring,
tamp liberally in order to fill all cavities and prevent air pockets.
If tamping does not eliminate all air pockets, drill small vent
holes through the base surface.
5.
Level off the grout to be flush with the top of the dam.
6.
Allow the grout to cure (usually 48 to 72 hours) before
tightening the foundation bolts or starting the pump. Tighten
pipe connections to inlet and outlet flanges.
7.
Check the pump alignment.
8.
After the grout cures, paint the exposed grout edges to protect
the grout from air and moisture.

.6 Pipes and connections

.6.1
Pipe supports, anchors or joints
Inlet and outlet pipes must be anchored, supported and restrained
near the pump to avoid application of forces and moments to the
pump in excess of those permitted by Peerless Pump.
Do not exceed the forces or moments specified on the
outline drawing when connecting pipes to the inlet or
outlet flanges.
Consider vibration dampening of the pump to help achieve optimum
operation and minimize noise and vibration.
Pipes must be arranged and supported so as to avoid
misalignment caused by expansion and contraction due to
temperature change
Noise and vibration are generated by the motor, pump and flow in
pipes and fittings. Minimizing noise and vibration depends on
correct installation and the state of the remaining system.
Eliminating noise and vibrations is best achieved via a concrete
foundation, vibration dampers and expansion joints.
Pipes must be cleaned mechanically and chemically and
flushed before installing the pump. Many issues with
pump packing, seal and seizure are due to improperly
cleaned systems.
Before installation inspect the pump internally for foreign matter that
may have entered the pump during shipping and storage.
