3.1.3 Foundation
We recommend that you install the pump on a
concrete foundation which is heavy enough to
provide permanent and rigid support for the entire
pump. The foundation must be capable of absorbing
any vibration, normal strain or shock. The concrete
foundation must have an absolutely level and even
surface.
Place the pump on the foundation, and fasten it. The
base plate must be supported on the whole area.
The following instruction applies when mounting the
pump in both vertical and horizontal position. Place
the pump on the foundation, and fasten it. See fig.
16.

Fig. 17 Foundation, vertical mounting
The recommended length and width of the
foundation are shown in fig. 17. Note that for pumps
with motor size below or equal to 30 kW, the length
and width of the foundation must be 200 mm larger
than the base plate.
For pumps with motor size equal to 37 kW or above,
the length and width must always be 1.5 x 1.5 (Lf x
Wf) m.
Fig. 18 Foundation, horizontal mounting
The foundation length and width must always be 200
mm larger than the length and width of the pump.
See fig. 18.
The mass of the foundation must be at least 1.5
times the total mass of the pump. The minimum
height of the foundation (hf) can then be calculated:
The density (δ) of concrete is usually taken as 2200
kg/m
3
.
In installations where noiseless operation is
particularly important, we recommend that you use a
foundation with a mass up to 5 times that of the
pump.
The foundation must be provided with anchor bolts
for fixing the base plate. See fig. 19.
Fig. 19 Bolt in foundation
When the anchor bolts are in position, place the
pump on the foundation. Then align the base plate
using shims, if necessary, so that it is completely
horizontal. See fig. 20.
