Low outlet pressure of magnetic pump

The flow rate of the magnetic pump is normal, but the pressure indicated by the pressure gauge doesn’t increase; the sound of the pump while it’s running is also normal. Three different pressure gauges have been tried, but the problem persists.
Should I install a backpressure valve?
Please provide the head of the pump, the density of the medium, the inlet pressure, and the reading on the pressure gauge. Just providing these figures alone doesn’t give any reference point, making it difficult to conduct an analysis. Magnetic pumps can also become decoupled.
I didn’t press it; I’ve been using it for several years, and it worked fine all that time
I’ve been using it for several years; it only started acting like this recently
