KEY: Fluid Outlet Pressure – Black Curves
Air Consumption – Gray Curves
NOTE: Recommended pump speed for continuous operation
(to shaded area): 60 cpm
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
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.
