Make a note of this pump's F number, also known as its Flow Fluctuation Figure. Use the F number with the % residual fluctuation required figure from the smoothness shown for each type of application. These two figures, the F figure and the % figure, applied to the size selection formula give you the smallest practicable damper size.

Find the "F" Valve of Your Pump - "F" is a correction Factor on the square of number of diplacers.
Example, Centrifugals are intrinsically good - have a high F, Sandwich diaphragm metering pumps have a low F.

F = 0.4

quintuplex plunger pump cross sectional view
A quintuplex plunger pump turned at 880 rpm, generates 60+ M3 per 8 Hr shift
2000 gals per hour x 3,800 ml per gallon / 60 minutes per Hr. x 5 piston per rev x 880 rpm = 28.8 ml/stroke
@73.5 Hz.

Selecting Pulsation Dampeners for Different Pump Systems.
Flow through pulsation dampers are at least 3 times more efficient than T off line accumulators.
Dampeners that do, flow goes through, but pressure pulsation does not.
