5.4 Foundations
Most pumps give the most satisfactory service when a rigid foundation is used. Foundations are usually made of
concrete, but can also be made of structural steel, in both cases they must be sturdy and non-vibrating.
If the foundation surface is concrete, it must be set horizontal and flat before the pumping equipment is placed. The
space required for a pumping unit and the placement of anchor bolts are defined by the drawings supplied by the
manufacturer.
The unit can be supported on a generously dimensioned foundation. This foundation must be completely flat, smooth
and level. The unit shall be fastened to this foundation by means of suitable anchor bolts to avoid possible vibrations
due to operation.
5.5 Anchor Bolts
VOGT S.A. supplies the pumping equipment with bases, these must be anchored to the foundation by means of anchor
bolts, as shown in figure 7 and applying the tightening torque according to table N° 4.

Once the process has been completed, it is advisable to mount a locknut on the bolt nuts to prevent them from loosening
during operation of the equipment.
5.6 Joints to Rigid Pipe System
For optimum operation of the motor-pump equipment, the piping should not exert stresses on it. The equipment can be
deformed, broken or misaligned when the piping is not aligned with the suction and discharge axes of the pump. The
position of the suction and discharge ports must be completely parallel, with their concentric axes, in order to minimize
stresses on the pump necks that could deform the pump or cause misalignment of the axes.
Do not use the pump as an installation fastening point. The suction and delivery piping must not produce stresses on the
suction and discharge ports of the pump that may exceed their maximum values. The pipes must be fixed to the walls or
floors of the pump room in such a way that the pump is not subjected to their weight, see figure 8.
