Air Operated Pump Curves
Air Operated Pump Curves
(OP)
Hi,
I am trying to read a pump curve for an air operated pump. The curves are for gallons per minute on the x-axis and total head on the y-axis. The lines are for air inlet psi and air consumption in SCFM. How would I design a system for pumping a number of gallons to a system under 5 psi? How can I find out air consumption? Would head just be suction head-discharge head?
Thanks

RE: Air Operated Pump Curves
Would it be:
Suction head(in)=NPSH(in)
Discharge Head(in)=[Pressure Drop of Discharge Line(psi)/density of liquid (lb/in^3)]+[backpressure(psi)/density(lb/in^3)]
Total Head(in)=Discharge head(in)-Suction Head(in)
Could someone give me the correct calculation scheme if this is incorrect? Thank You.
