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 pres-
sure (vertical scale) requires approximately 50 scfm (1.4 m
3
/min) air consumption at 70 psi (0.49 MPa, 4.9 bar) inlet
air pressure.
Test Conditions: Pump tested in water with
PTFE diaphragm and inlet submerged
