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.

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)
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).

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.
