To find Outlet Pressure (MPa/bar/psi) at
a specific delivery (liter/min or gpm) and
operating hydraulic pressure (MPa/bar/
psi):
1. Locate desired delivery along bottom
of chart.
2. Read vertical line up to intersection
with selected fluid outlet pressure
curve (black curves). Curve slopes
down from left to right. Follow left to
scale and read outlet pressure.
To find Motor Hydraulic Oil
Consumption (liter/min or gpm) at a
specific delivery (liter/min or gpm) :
1. Locate desired delivery along bottom
of chart.
2. Read vertical line up to intersection
with hydraulic oil consumption curve
(gray curve). Curve slopes up from
left to right. Follow right to scale and
read hydraulic oil consumption.
