Is this pool new to you?
Your IFCS has valves that cycle through different zones of pop-up heads in your pool. And your filter pressure can vary depending on which IFCS cleaning zone is active.
I don't understand what you mean by "he pump have the waterfall type of circulation."
Do you have specific problems?

Does it seem like to pressure increase and drop is related to the pump itself - like a surging sound? Or does the pump sound good and steady, but the pressure gauge is just changing on its own? Do you notice any pressure difference at the return jets?
As the distribution valve changes between zones all ports are closed for just an instant before the next opens. Essentially a slight "dead head" condition. Pressure goes up as the water has nowhere to go for just a second.

Who is the manufacturer of your IFCS?
Does the pool also have a separate set of returns?
Explain this " waterfall type ofcirculation".
The change of pitch is related to the pressure change and the water flow thru the water distribution valve as itcycles thru the zones.
Post another pic of the equipment from a little further away so we can see all the plumbing.
In the water distribution valve, as one zone valve is almost closed another valve starts to open. Due to the restricted flow, the pressure increases. When a zone valve is fully open there is less restriction and the pressure decreases.
This is totally normal. In reality, no "dead heading" should occur. There should always be a valve that is partially open as the gearset rotates - near the end of one zone, the next zone starts.
