A selectively bonded two-ply diaphragm for a diaphragm pump having adjacent first and second layers of the diaphragm which are selectively bonded at the interface between the layers in at least one attachment portion, which is adapted for attachment to a pump. A working portion is provided in which the first and second layers are free to move relative to one another at the interface. The attachment portion may include a central portion which is adapted for attachment to a diaphragm rod of a pump and a peripheral portion surrounding the central portion which is adapted for stationary attachment to a pump housing. The working portion joins the peripheral portion and the central portion. Selective bonding of the diaphragm is by at least partially bonding or substantially bonding the first and second layers at the interface in the peripheral portion, the central portion, or both.
A selectively bonded two-ply diaphragm for a diaphragm pump, the diaphragm having adjacent first and second layers having an interface therebetween, comprising:
