Noise levels measured with the pump mounted on the floor,
using Rubber Foot Kit 819.4333. Sound power measured
per ISO Standard 9216.
Example of Finding Pump Air Consumption and Air Pressure at a Specific Fluid Delivery and Discharge Head:
To supply 20 gpm (76 liters) fluid flow (horizontal scale) at 40 psi (0.28 MPa, 2.8 bar) discharge head pressure (vertical scale) requires
approximately 20 scfm (0.56 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.
