TEST CONDITIONS
The pump had a 2–piece PTFE diaphragm and was tested
in water with the inlet submerged.
Example of Finding Pump Air Consumption and Air Pressure at a Specific Fluid Delivery and Discharge Head:
To supply 38 liters fluid flow (horizontal scale) at 1.4 bar discharge head pressure (vertical scale) requires approximately
0.28 N m
