4 INSTALLATION
4.1 Location
The pump should be located to allow room for
access, ventilation, maintenance and inspection with
ample headroom for lifting and should be as close as
practicable to the supply of liquid to be pumped, and
to the venting system.
Disconnect the switching enclosure support from the
pump support by removing the fastening bolts. The
switching enclosure support must be off-set with
respect to the pump motor base.
4.2 Foundation
There are many methods of installing
pump units to their foundations. The correct method
depends on the size of the pump unit, its location
and noise vibration limitations. Non-compliance with
the provision of correct foundation and installation
may lead to failure of the pump and, as such, would
be outside the terms of the warranty. The base plate
should be mounted onto a firm foundation, either an
appropriate thickness of quality concrete or sturdy
steel framework. It should NOT be distorted or pulled
down onto the surface of the foundation, but should
be supported to maintain the original alignment.
Anchor bolts must be in accordance with the foot
bolt holes. Use anchor bolts of accepted standards
and sufficient to ensure safe fitting in the foundation.
Particularly, this applies to individual plates where
the anchor bolts have to withstand the driving
torque.
NF E 27 811
Provide sufficient space in the foundation to
accommodate the anchor bolts. If necessary,
provide concrete risers.
4.2.1 Setting the base plate for anchoring
- Clean the foundation surface thoroughly.
- Put shims on the foundation surface (approx 20-25
mm thick), one on each side of the bolt hole (as an
alternative, leveling screws can be used).
- 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.
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
Prepare the site for grouting. Before grouting clean
the foundation surface thoroughly and provide
external barriers as shown:
