To find Outlet Pressure
(MPa/bar/psi) at a specific
delivery (liter/min or gpm) and operating air pressure
(MPa/bar/psi):
1. Locate desired delivery along bottom of chart.
2. Read vertical line up to intersection with
selected fluid outlet pressure curve (black
curves). Curve slopes from left to right.
Follow left to scale and read outlet pressure.
To find Pump Air Consumption

/min or
CFM/min) at a specific delivery (liter/min or gpm)
and operating air pressure (MPa/bar/psi):
1. Locate desired delivery along bottom of chart.
2. Read vertical line up to intersection with
selected air consumption curve (gray curves).
Curve slopes from right to left. Follow right to
scale and read air consumption.
