These charts show discharge head fluctuations for a
diaphragm pump with and without a dampener. By
reviewing the variation in pressure, the level of dampening
can be estimated for an application. For example, the head
pressure generated by a 25 mm (1”) pump operating at
6.89 bar (100 psig) air inlet pressure and 6.2 bar (90 psig)
head pressure varies between 1.7 bar (25 psig) and 7.2 bar (104 psig) resulting in a total pressure fluctuation of
5.5 bar (79 psig) for each stroke. When an XSD1/AAAA/
TNU/TF dampener is installed in the application, the
head pressure varies between 4.8 bar (69 psig) and 6.6
bar (96 psig) resulting in a pressure fluctuation of only
1.9 bar (27 psig). This results in a 67% reduction in head
pressure fluctuation.
