Pulsation Dampener Calculator

Measurement

V= Volume per Stroke in Cubic Inches (in*)
GPH = Volume per Stroke in Cubic Inches (in3) = (GPH/60 / Strokes/Min) x 231
GPM = Volume per Stroke in Cubic Inches (in3) = (GPM / Strokes/Min) × 231

Minimum Discharge Pressure

HIDDEN – USED IN FINAL PD SIZING CALCULATION
{System Pressure (psi):4} * (1-{Strokes per Minute:5}/100)

System Pressure

PSI – Input Whole Number

Maximum Discharge Pressure

{System Pressure} *(1+(Strokes per Minute/100))

Desired Dampening

(+/- of system pressure) 1-100 (recommended 2.5% – 5%)

Calculated Dampener Size

V1 – (({Volume per stroke:24}*{Type of Pump:17})* {Strokes per Minute:5})/ 1-{Mean System Pressure value:25}/{Maximum Discharge Pressure:10}

Type of Pump

Calculated Dampener Size

V2 – ((({Volume per stroke:24} * {Type of Pump:17}) * {Strokes per Minute:5}) / (1 – ({Mean System Pressure value:25} / {Maximum Discharge Pressure:10}))) * ((({Volume per stroke:24} * {Type of Pump:17}) * {Strokes per Minute:5}) / (1 – ({Mean System Pressure value:25} / {Maximum Discharge Pressure:10}))) * ((({Volume per stroke:24} * {Type of Pump:17}) * {Strokes per Minute:5}) / (1 – ({Mean System Pressure value:25} / {Maximum Discharge Pressure:10})))

Volume per stroke

GPM – Volume per Stroke in Cubic Inches (in3) = (GPM / Strokes/Min) × 231
GPH – Volume per Stroke in Cubic Inches (in3) = (GPH/60 / Strokes/Min) x 231
value (hidden) used in final PD sizing calculation

Volume per Stroke

Cubic Inches – (({GPH:13}/60 + ({GPM:14} * 60 / 60)) / {Strokes per Minute:5}) * 231
