SIMPLEX PACKED PLUNGER PUMP

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. See below for figures

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

F = 1.15

 Packed plunger pumps generally have the least dead space within the pump head and the smallest check valve pocket dead volume, they therefore have the best volumetric efficiency . Accordingly the accelerate the liquid into the system form the beginning of stroke. The gradual acceleration produces the lowest level of pipe reaction and so the least level of pressure pulsation. For this reason the F factor number is highest of all rotary drive motion reciprocating machines.

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.
