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 38 mm (1-1/2
″
) pump operating at 5.5 bar (80 psig) air inlet pressure and 4.8 bar (70 psig) head
pressure varies between 1.2 bar (18 psig) and 5.1 bar (74 psig) resulting in a total pressure fluctuation of 3.9 bar (56
psig) for each stroke. When an ISD420/SZSS/TBL dampener is installed in the application, the head pressure varies
between 3.9 bar (56 psig) and 2.4 bar (35 psig) resulting in a pressure fluctuation of only 1.4 bar (21 psig).
