Performance Curves
A pump’s ability to deliver material is based on the pressure (psi/Bars) and quantity
(cfm/lpm) of air supplied to the motor and the amount of material discharge [back] pressure to
be overcome within the system. This chart contains curves based on three different air
pressures. The curves relate delivery in pounds (kilograms) per minute (X axis) to air
consumption in cubic feet (liters) per minute (right Y axis) and to material discharge pressure in
psi/Bars (left Y axis).
