Performance curves

A pump’s ability to deliver material is based on the pressure (psi/bar) 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 four 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/bar (left Y axis).
