determining suction and delivery lines of centrifuagal pump
(OP)
For a centrifugal pump
what significant signs I can see from outside of a real pump mounted in a system in order to differentiate between suction and delivery lines of centrifugal pump ?

are you sure ? I thought that was for the compressor only.
The only thing I can think about now is that the discharge might have a check valve while suction not . Maybe the discharge might have a flow control valve and suction not as well . Is there another sign we could tell ?

This is something you would normally recognize in pumping stations (booster pumps).

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

It is easy to identify the the suction and discharge for an end suction pump. But not that simple for
vertical inline pump, Multistage, axial split case, VS6 type. Here the OP mentioned about a complete mounted system.

If the suction and discharge flanges are different sizes, the larger one is the suction.
If there is a check valve in one of the lines, that is probably the discharge.
