Performance curves
A pump's ability to deliver fluid is based on
the pressure (psi (bar)) and quantity (cfm (lpm))
of air supplied to the motor and the amount
of fluid discharge (back) pressure to be over-
come within the system

This chart contains curves based on three
different air pressures The curves relate
delivery in gallons (liters) per minute (X axis)
to air consumption in cubic feet (liters) per
minute (right Y axis) and to fluid discharge
pressure in psi/bar (left Y axis)
