Calculate Fluid Outlet Pressure (black curves)

To calculate fluid outlet pressure (MPa/bar/psi) at a specific fluid flow (lpm/gpm) and operating air pressure (MPa/bar/psi), use the following instructions and pump data chart.

1.Locate desired fluid flow along bottom of chart.

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

Calculate Pump Air Consumption (gray curves)

To calculate pump air consumption (m3/min or scfm) at a specific fluid flow (lpm/gpm) and air pressure (MPa/bar/psi), use the following instructions and pump data chart.

1.Locate desired fluid flow along bottom of chart.

2.Follow vertical line up to intersection with selected air pressure curve (gray). Follow horizontally right to read air consumption.
