Performance Chart
Example of Finding Pump Air Consumption and Air Pressure at a Specific Fluid Delivery and Discharge Head:
To supply 60 gpm (227 liters) fluid flow (horizontal scale) at 40 psi (0.28 MPa, 2.8 bar) discharge head pressure (vertical scale) re- quires approximately 50 scfm (1.40 m#/min) air consumption at 70 psi (0.49 MPa, 4.9 bar) inlet air pressure.
