Performance curves
Ability of pump to deliver material is based
on pressure (psi/bar) and quantity (cfm/lpm)
of air supplied to motor and amount of
material discharge (back-pressure) to be
overcome within system.
This chart contains curves based on three
different air pressures. These curves relate
delivery in gallons (liters) 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).
