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
pressure curve. Follow left to scale and read fluid outlet pressure.
To find Pump Air Consumption (m#/min or scfm) 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 air consump-
tion curve. Follow left to scale and read air consumption.
