INTENSIFIER PUMP intensifier symbol

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.

The Systems Response:
frequency chart

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 = 1.3

intensifier symbol
Fluid driven differential area pressure intensifiers generally have two features which result in lower levels of discharge pulsation than might otherwise be expected.
A). The ratio of stroke length to diameter is wide. This results in minimal dead volume. B). The return stroke is normally faster than the discharge stroke, so the volume necessary to sustain flow in less than would be required for an equal discharge and return stroke machine. Hydraulically driven versions are highly energy efficient also.
That is why the F factor in better, causing a smaller damper selection

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.
