To find Fluid Outlet Pressure (bar/psi/MPa) at a specific fluid flow
(lpm/gpm) and operating air pressure (bar/psi/MPa):
1. Locate desired flow along bottom of chart.
2. Follow vertical line up to intersection with selected fluid outlet
pressure curve (black). Follow left to scale to read fluid outlet
pressure.
T
o find Pump Air Consumption (m  /min or scfm) at a specific fluid
flow (lpm/gpm) and air pressure (bar/psi):
1. Locate desired flow along bottom of chart.
2. Read vertical line up to intersection with selected air consumptio
n
curve (gray). Follow right to scale to read air consumption.
