LOST MOTION PUMP lost motion 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.

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.

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.
