When I built our watermaker I installed a pulsation damper in the high pressure feed line. It's a pressure vessel with a diaphragm in the middle and high pressure gas on one side and the fluid on the other side. The gas acts to damp out the pulsation from the high pressure pump. Similar to the accumulator in the pressure water system, just much higher pressure.
