How to Read Pump Performance Flow Rate

Charts below are for example only.
See pump model web pages for their performance charts.

如何读图表

Use your discharge pressure and desired flow rate to estimate required air pressure, resultant air usage, and cycle rate.

步骤1

Draw a horizontal line at your discharge pressure.
(e.g. 30 psi / 2 Bar)

步骤2

Draw a vertical line at your desired flow rate.
(e.g. 90 lpm / 5.4 m3/hr / 23.8 gpm)

步骤3

At line intersect, estimate required air pressure.
(e.g. 70 psi / 4.8 Bar)

步骤4

At line intersect, estimate resultant air consumption.
(e.g. 28 SCFM)

步骤5

At line intersect, estimate resultant cycle rate (e.g. 190 CPM).
