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 (black). Follow left to scale to read
fluid outlet pressure.
To find Pump Air Consumption (m
/min or scfm) at a spe-
cific 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 con-
sumption curve (gray). Follow right to scale to read air
consumption.
