To find Fluid Outlet Pressure (bar/psi) at a specific fluid flow (lpm/gpm) and operating air pressure (bar/psi):

1.Locate desired flow along bottom of chart.

2.Follow vertical line up to intersection with selected fluid outlet pres- sure curve (black). Follow left to scale to read fluid outlet pressure.

To 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 consumption curve (gray). Follow right to scale to read air consumption.
