Pump Performance Charts (see pages 28-33)
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 operat-
ing 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.
