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 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 (bar) (left Y axis)
