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

A0.7 MPa, 7 bar (100 psi) air pressure B 0.49 MPa, 4.9 bar (70 psi) air pressure C 0.28 MPa, 2.8 bar (40 psi) air pressure

To find Outlet Pressure (MPa/bar/psi) at a specific delivery (liter/min or gpm) and operating air 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 curves). Curve slopes from left to right. Follow left to scale and read outlet pressure.

To find Pump Air Consumption (m3/min or CFM/min) at a specific delivery (liter/min or gpm) and operating air pressure (MPa/bar/psi):

1.Locate desired delivery along bottom of chart.

2.Read vertical line up to intersection with selected air consumption curve (gray curves). Curve slopes from right to left. Follow right to scale and read air consumption.
