To find Fluid Outlet Pressure (psi/MPa/bar) at a spe-
cific fluid flow (lpm/gpm) and operating hydraulic pres-
sure (psi/MPa/bar):
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.
See Models on page 3 for your pump part number.
Key:
A 10.3 MPa, 103 bar (1500 psi)
hydraulic pressure
B 7.2 MPa, 72.4 bar (1050 psi)
hydraulic pressure
C 4.1 MPa, 41 bar (600 psi)
hydraulic pressure
NOTE: The shaded area within
the table shows the recom-
mended range for continuous
duty circulation applications.

To find Motor Hydraulic Oil Consumption (l/min. or
gpm) at a specific fluid flow (l/min. or gpm):
1. Locate desired flow along bottom of chart.
2. Read vertical line up to intersection with hydraulic oil
consumption curve (dashes). Follow right to scale to
read hydraulic oil consumption.
