(Solved) I bought a high-pressure plunger pump, and the pressure gauge at the outlet fluctuates between 4 Mpa and 6 Mpa. Is this normal?

How can the outlet pressure of a plunger pump be kept constant? Actually, the problem is quite simple: the pressure gauge used at first was not shock-resistant, so a shock-resistant pressure gauge (the kind that contains liquid) was installed, and the problem was resolved. Thank you all.
Installing an air chamber or accumulator can reduce pulsation.
The plunger pump I bought is the kind used for portable car washing; it has only one water inlet, one water outlet, and a knob for adjusting pressure – there’s no mechanism for regulating backflow Please make it explicit. Thank you
I’m a water pump. Where can I find information on what you’re referring to? Thank you

Ask the pump manufacturer about this; they might have relevant products or recommendations
Install a buffer with an air bag at the outlet.
