Pump performance
Pump's ability 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 (page 7) contains
curves based on three different air pres-
sures. 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).
