Viscosity Adjustment Curve

FTI Air pump curves are based on viscosity of water (1 cP). Higher viscosities have a detrimental effect on the rated capacity. An adjustment must be made when pumping viscous media. Viscous fluids reduce capacity and increase pipe friction.

Use the chart below to adjust pumping capacity. The chart is an approximate guide. Actual pump performance may vary depending upon the actual flow characteristics of the media being pumped.
