Pulsationsdämpfer für die Amplitude der Druckwellen Spitzenwerte

Check the amplitude of any highly excitational pressure spikes in pump literature aka "Velocity Jump" causing "Joukowsky shock"

You can reduce Velocity Jump Shock to a generally insignificant figure in 4 steps:
1. Select a damper with an ID 12 times the diameter of the inlet connection.
2. Have an outlet 1/2 the area of the inlet.
3. Increase the volume by 3 x the in-efficiency.
4. Decrease the cushion pre-fill pressure proportionately to the volume increase, from 80% of system pressure to as low as 50%.
