Pump performance
Ability of pump to deliver material is based
on pressure (psi/bars) and quantity (cfm/
lpm) of air supplied to motor and amount of
fluid discharge backpressure to be overcome
within system
Pump performance contains curves based
on three different air pressures Curves
relate delivery in gallons (liters) per minute

(X axis) to air consumption in cubic feet
(liters) per minute (right Y axis) and to mate-
rial discharge pressure in psi (bars) (left Y
axis)
