FLUID FLOW––gpm (lpm)

Test Fluid: No. 10 weight oil at 75_ F (23.9_ C)

To find fluid outlet pressure at a specific fluid flow and operating air pressure:

1.Locate desired fluid flow along bottom of chart.

2.Follow vertical line up to intersection with selected fluid outlet pressure curve (black).

3.Follow left to scale to read fluid outlet pressure.

To find pump air consumption at a specific fluid flow and air pressure:

1.Locate desired flow along bottom of chart.

2.Read vertical line up to intersection with selected air consumption curve (gray).

2. Follow right to scale to read air consumption.
