3.2 - HOW TO USE THE PERFORMANCE CURVES
Example :
AD60 - 30 l/minute against a discharge pressure of 2.0 bar.
Pump selection
Find the required flow (30 l/min) along the horizontal axis. Go vertical to the intersection with 2 bar fluid
outlet and read the air pressure required, ~ 3,5 bar.
Air consumption
Again - find the required flow (30 l/min) along the horizontal axis. Go vertical to the intersection with the
required air pressure (3,5 bar) and read the air consumption to the left.
In the example, ~ 180 l/min.
