PUMP PERFORMANCE CHART
To find Outlet Pressure
(bar/psi) at a specific delivery (liter/min–
GPM) and operating air pressure (bar/psi):
1. Locate desired delivery along bottom of chart.
2. Read vertical line up to intersection with selected fluid outlet pres-
sure curve. Curve slopes from left to right. Follow left to scale and
read outlet pressure.
To find Pump Air Consumption
(m3/min–CFM) specific delivery
(liter/min–GPM) and operating air pressure
(bar/psi):
1. Locate desired delivery along bottom of chart.
2. Read vertical line up to intersection with selected air consumption
curve. Curve slopes from right to left. Follow right to scale and
read air consumption. Follow left to scale and read outlet pres-
sure.
