Pump Performance Charts (see pages 25-27)
Fluid Outlet Pressure
To find fluid outlet pressure (MPa/bar/psi) at a specific
flow (lpm/gpm) and operating pressure (A/B/C):
1. Locate desired flow at bottom of chart.
2. Follow vertical line up to intersection with selected
operating pressure curve (solid line). Follow left to
scale to read fluid outlet pressure.
Pump Air or Hydraulic Oil Consumption
To find air or hydraulic oil consumption at a specific flow
(lpm/gpm) and operating pressure (A/B/C):
1. Locate desired flow at bottom of chart.
2. Follow vertical line up to intersection with selected
operating pressure curve (dashed line). Follow left
to scale to read air or oil consumption.
