Test Conditions: Pump tested in water with inlet submerged
To find Fluid Outlet Pressure
(psi/MPa/bar) at a specific fluid flow (gpm/lpm) and
operating air pressure (psi/MPa/bar):
1. Locate fluid flow rate along bottom of chart.
2. Follow vertical line up to intersection with selected
fluid outlet pressure curve.
3.Follow left to scale to read fluid outlet pressure.
To find Pump Air Pressure
(scfm or m
3
/min) at a specific fluid flow (gpm/lpm) and
operating air pressure (psi/MPa/bar):
1. Locate fluid flow rate along bottom of chart.
2. Read vertical line up to intersection with selected air
consumption curve.
3. Follow left to scale to read fluid outlet pressure.
