Abstract: A diaphragm structured for use in a diaphragm pump useful to pump a working fluid includes a first non-planar layer and a second non-planar layer. The second non-planar layer is independent from the first non-planar layer, but engaged to the first non-planar layer so that the first non-planar layer and the second non-planar layer form a closed space therebetween and travel together while flexing in an intake direction or a discharge direction within a pumping assembly of a diaphragm pump.
