5.3 Foundations
Most pumps give more satisfactory service when a rigid foundation is used. Foundations are usually made of concrete,
but can also be made of structural steel, in either case 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 must be fastened to this foundation by means of suitable anchor bolts to avoid possible vibrations
due to operation.
5.4 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 Nº 4.

Once the process is completed, it is advisable to mount a locknut on the bolt nuts to prevent them from loosening during
operation of the equipment.
