Diaphragm pump calculation for sizing - Pump engineering ...

Dec 16, 2009  2. Discharge side. You have to intersect your pump performance curve (head vs flow rate) with the system response curve for your rated flow. Be aware that positive displacement pumps have a practically a vertical performance curve, so flow is nearly constant.
