Fluid Outlet Pressure – Black Curves
Air Consumption – Gray Curves
A
6.2 bar (0.62 MPa, 90 psi) Air Pressure
B
4.9 bar (0.49 MPa, 70 psi) Air Pressure
C
2.8 bar (0.28 MPa, 40 psi) Air Pressure
To find fluid outlet pressure (bar/MPa/psi) at a
specific fluid flow (lpm/gpm) and operating air
pressure (bar/MPa/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 read fluid outlet pressure.
To find pump air consumption (m
#/min or scfm)
at a specific fluid flow (lpm/gpm) and air pressure
(bar/MPa/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.
