Suction Pump Vs Pressure Pump at Alan Horace blog

Suction Pump Vs Pressure Pump. End suction pumps are better suited for high flow rate applications, while inline pumps are more suitable for moderate flow rates. The pump produces pressure and the difference in pressure across the pump is the amount of pressure energy available to the system. To avoid cavitation, the value of the suction pressure does not matter. But in a few technical applications, you might also need to calculate the pump's npsh, or net positive suction head. While some pump manufacturers that use pressure (differential pressure which is measure the deviation between suction and discharge flange ~ head) to characterize their pumps, this is not the most “accurate” way to do so (because of friction and loss along the pipe line). It does matter how much higher it is over vapor pressure of. The available npsh a should in general be significant higher than the required npsh r to avoid that head loss in the suction pipe and in the pump casing, local velocity accelerations and pressure.
