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.
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).
Pump performance
Delivery versus discharge pressure and air consumption.
