4 INSTALLATION
Equipment operated in hazardous locations
must comply with the relevant explosion protection
regulations. See section 1.6.4, Products used in
potentially explosive atmospheres.
All equipment must be grounded.
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.
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 seave 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.
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 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.
d) If anchor bolts have been pre-cast in the
foundation slightly tighten the anchor bolts.
Otherwise let them hang in the foundation holes.
