PUMP DELIVERY (Test Fluid: No. 10 Motor Oil)

A10.3 MPa, 103 bar (1500 psi) hydraulic oil pressure

B6.9 MPa, 69 bar (1000 psi)

hydraulic oil pressure

C3.4 MPa, 34 bar (500 psi) hydraulic oil pressure

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.
