Griffco Valve Pulsation Dampener Sizing Calculator

 

Imperial Metric

 

Pulsation Dampener

Step #1: Calculate the Volume per Stroke.


Volume / Stroke (in³) = (GPH / Strokes/Min) x 231


Step #2: Fill in the remaining values and calculate.


Dampener Size (C) = (V) x (K) x (SP/ Pmin)y
1 – (SP/ Pmax)y
Where V = Volume / Stroke (in3)
SP = Mean System Pressure (Pmin + Pmax) /2
Pmin = Minimum Discharge Pressure in PSI
Pmax = Maximum Discharge Pressure in PSI
K = Constant from the Pump-type Table shown in menu
Y = 1 (if charged with Compressed Air); 0.714 (if charged with Nitrogen)
