Each pump must have its own suction pipe; the installation of two or more pumps with a
common suction pipe length causes the pump to work less efficiently.
The length of the suction pipe must be reduced as much as possible to minimize pressure
losses in such segment; higher pressure losses in the discharge line do not adversely affect
the correct operation of the pump (if they do not exceed the delivery limits stamped on rating
plate).
Furthermore, it is necessary to check that siphons are not created in the suction pipe, since
the formation of air pockets generates vibrations and stresses which are not compatible with
the correct operation of the pump and may obstruct the pump priming at startup.
In case of installation below head, the pump does not ensure to be able to intercept the flow
of fluid as a shut-off cock or a proper stop valve.
