Pump Package Performance Charts

Calculate Fluid Outlet Pressure

To calculate fluid outlet pressure (psi/MPa/bar) at a spe-cific fluid flow (gpm/lpm) and operating air pressure (psi/MPa/bar), use the following instructions and pump data charts.

1. Locate desired flow along bottom of chart.

2. Follow vertical line up to intersection with selected fluid outlet pressure curve. Follow left to scale to read fluid outlet pressure.

Calculate Pump Air Flow/Consumption

To calculate pump air flow/consumption (scfm or

m3/min) at a specific fluid flow (gpm/lpm) and air pres-sure (psi/MPa/bar), use the following instructions and pump data charts.

1. Locate desired flow along bottom of chart.

2. Follow vertical line up to intersection with selected air flow/consumption curve. Follow right to scale to read air flow/consumption.
