The pressure gauge of the power compressed air used in the pneumatic diaphragm pump fluctuates; is the minimum value of this fluctuation achieved when the diaphragm is in a stretched state or in its natural state?

Excuse me, sir: why is the power supply for pneumatic diaphragm pumps – a type of diaphragm pump – unstable? Why does the pressure gauge on them keep fluctuating? For example, if the range of vibration is 0.35–0.45 MPa, is this value of 0.35 MPa applied when the bellows are stretched, or is it the value in the bellows’ natural state? Please help me understand this. Thank you
It seems not to be closely related to this; the fluctuations in the pressure gauge are caused by the back-and-forth movement of air, as well as the exhaust of air when the air holes on the left and right are connected. This is just my personal opinion.
