FLUID FLOW
(Pump tested in No. 10 weight oil with inlet submerged)
How to use this chart:
Step 1: Locate the required fluid flow rate along
bottom axis of chart.
Step 2: Follow vertical line to the intersection with
the solid curve (A, B, C or D – based on your air
inlet pressure).
Step 3: Follow to left axis to read fluid outlet
pressure.
Step 4: From Step 2, follow vertical line up or down
to the intersection with the dotted line
(A, B or C or D– based on your air inlet pressure)
then follow to right axis to read air
consumption.
Example
To obtain 3 gpm (11.4 lpm) at approximately 150 psi
(10.3 bar, 1.0 MPa) you will need 100 psi (7 bar, 0.7 MPa) of air
pressure. The air consumption will be approximately 7 scfm.
