Performance Charts
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.
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 left to scale to
read hydraulic oil consumption.
