Legend: ND = No Dampener; WD = With Dampener
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 76 mm (3
″
) 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 7.8 bar (113 psig) resulting in a total pressure fluctuation of 6.1 bar (88
psig) for each stroke. When an ISD1520/SZSS/TBL dampener is installed in the application, the head pressure varies
between 4.3 bar (62 psig) and 5.6 bar (81 psig) resulting in a pressure fluctuation of only 1.3 bar (19 psig).
