This chart shows 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 1.4 bar (20 psig) and 7.9 bar (115 psig) resulting in a total pressure fluctuation of 6.6 bar (95
psig) for each stroke. When an ISD220/SZSS/TBL dampener is installed in the application, the head pressure varies
between 3.6 bar (52 psig) and 6.4 bar (93 psig) resulting in a pressure fluctuation of only 2.8 bar (40 psig).
