To find Fluid Outlet Pressure (MPa/bar/psi) at a specific fluid flow
(lpm/gpm) and operating hydraulic oil pressure (MPa/bar/psi):
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 Pump Hydraulic Oil Consumption (lpm or gpm) at a specific
fluid flow (lpm/gpm) and hydraulic oil pressure (MPa/bar/psi):
1. Locate desired flow along bottom of chart.
2. Read vertical line up to intersection with oil consumption curve
(gray). Follow right to scale to read oil consumption.
