6. INSTALLATION
6.1 INSTALLATION POINT
(1) Install the e quipment in an easily accessible place in order to carry out overhauls and maintenance.
(2) Prohibit access to unauthorized persons by using related closure points.
(3) Place the equipment as close as possible to the water supply, making sure that the difference in
height between the water surface and the pump shaft is minimal and that the length of the suction
pipe is as short as possible.
(4) The sum between t he suction pressure and the gauge pressure of the pump must always be
less than the minimum permissible pressure (see section 4 - Specifications).
6.2 LIFTING
In order to move the electric pump or the individual pump you must lift the load by means of straps, creating
an angle of less than 60 degrees, as shown in the figure:
6.3 CEMENTED BASE
One should note that electric pump units must be fixed in a stable and durable manner to a solid cemented
base so that the axes of the pumps and the motors always remain correctly and securely aligned. The
cement base must be sufficiently rigid, permanent and aligned, as well as being located on ground capable
of bearing a permitted load of adequate support facilities. The top part of the unit must rest completely
on the cemented base; once the top part has been secured, the alignment of the coupling needs to be
checked again.
If you need to limit, as much as possible, the vibrations of the equipment by using elastic dampers, the
latter should not be placed directly under the metal profiles, but instead, you will need to produce a solid
plate with a weight of one and a half times or two times the overall weight of the unit, arranging the dampers
under the assembly that combines the top part with the plate. There are several valid methods although
this plate is typically made with concrete and its dimensions exceed those of the top by about 1.875” (0.2
meters) on all four sides.
Ensure that there are no personnel exposed to
danger during the operation. To lift the assembly,
do not use the attachment points of the motor or the
pump because they may not have been designed
to bear the combined weight of the pump, motor
and base.
