Pump performance
Pump's ability to deliver material is based on
pressure (psi (bar)) and quantity
(ft
3
/min (l/min)) 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
material discharge pressure in psi (bar) (left
Y axis).
