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 appropriate for the foot bolt
holes. Use anchor bolts of accepted standards and
sufficient length so that they may be clamped safely
in the grout.
NF E 27 811
Provide sufficient space in the foundation to
accommodate the anchor bolts. If necessary,
provide concrete gullets.
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 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.
