A diaphragm assembly for a fluid driven diaphragm pump includes a piston having an inflexible core. This core includes a hub with a plate extending radially from about the periphery of the hub. The piston further includes a unitary diaphragm body molded with the inflexible core in situ. The unitary diaphragm body has a plurality of connective tendons extending through the plate. A thermoplastic coating extends about the inflexible core between the core and the molded unitary diaphragm body having a thermally miscible surface with the thermoplastic coating. An inflexible backing plate extends in juxtaposition with the diaphragm.
