Pump performance
Ability of pump to deliver material is based
on pressure (psi/bar) and quantity (cfm/lpm)
of air supplied to motor and amount of fluid
discharge backpressure to be overcome
within system.
Fig. 2 contains curves based on three
different air pressures. 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).
