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
in reference to XSD2 BNS 100/90, the head pressure
generated by a 51 mm (2") pump operating at 6.89 bar (100
psig) air inlet pressure and 6.2 bar (90 psig) head pressure
varies between 0.4 bar (6 psig) and 7 bar (102 psig)
resulting in a total pressure fluctuation of 6.6 bar (96 psig)
for each stroke. When an XSD2/AAAA/BNS/BN dampener
is installed in the application, the head pressure varies
between 4.7 bar (68 psig) and 6.8 bar (99 psig) resulting in
a pressure fluctuation of only 2.1 bar (31 psig). This results
in a 68% reduction in head pressure fluctuation.
