End Suction Centrifugal
5. Suction systems:
- The bottom end of the suction pipe must remain submerged and at a depth of at least twice the
diameter of the pipe (2D) and at a distance from the bottom of 1 time to 1 and a half times the diameter
(1~1.5 D).
- Fit a bottom valve with a filter at the beginning of the suction pipe to prevent the entry of any foreign
bodies.
-The suction pipe will be installed with an upward gradient towards the pump (of more than 1%) to avoid
the formation of air bubbles. The pipes and other accessories must be connected in such a way so as
not to create any air intake between the different elements.
- Make sure that the suction pipe is as short and straight as possible and try to avoid any unnecessary
curves or additional length. Do not install any shut-off valve in this section.
- Unless the installation project indicates something different, use the dimensions for the suction pipe
and eccentric reduction recommended in this Table. The eccentric reduction will be installed with an
upward gradient towards the pump to avoid the formation of air bubbles.
6. In systems where a booster pump is present:
- The installation of a shut-off valve is recommended in the suction pipe to facilitate dismantling and
overhauls.
- Install the suction pipe with an upward gradient towards the pump to avoid the formation of air bubbles.
