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 urves). Curve slopes
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 from right
to left. Follow right to scale and read
hydraulic oil consumption.
