Performance Chart - 1590
Test Conditions: Pump tested in water with inlet submerged
Fluid Pressure Curves
A
at 120 psi (0.7 MPa, 7 bar) operating air pressure
B
at 100 psi (0.7 MPa, 7 bar) operating air pressure
C
at 70 psi (0.48 MPa, 4.8 bar) operating air pressure
D
at 40 psi (0.28 MPa, 2.8 bar) operating air pressure
T
o find Fluid Outlet Pressure
(
psi/MPa/bar) at a specific fluid flow (gpm/lpm) and
o
perating air pressure (psi/MPa/bar):
1. Locate fluid flow rate along bottom of chart.
2
. Follow vertical line up to intersection with selected
operating air pressure curve.
3
. Follow left to scale to read fluid outlet pressure.
Air Consumption Curves
A at 120 psi (0.7 MPa, 7 bar) operating air pressure
B at 100 psi (0.7 MPa, 7 bar) operating air pressure
C at 70 psi (0.48 MPa, 4.8 bar) operating air pres-
sure
D at 40 psi (0.28 MPa, 2.8 bar) operating air pres-

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
operating air pressure.
3. Follow left to scale to read air consumption.
