Abstract: Illustrative embodiments of diaphragm assemblies for diaphragm pumps and methods for manufacturing such diaphragm assemblies are disclosed. In at least one illustrative embodiment, a diaphragm pump may include an inflexible central core and a flexible diaphragm body surrounding the inflexible central core. The inflexible central core may include a reinforced thermoplastic and the flexible diaphragm body may include a thermoplastic elastomer. The flexible diaphragm body is bonded directly to the inflexible central core. The diaphragm assembly may include a mounting bolt having a head end and a threaded end. The inflexible central core surrounds the head end of the mounting bolt and the threaded end of the mounting bolt extends outside of the inflexible central core. The inflexible central core may include multiple raised features that cooperate to define cavities in the inflexible central core. The flexible diaphragm body fills the cavities of the inflexible central core.
