Illustrative embodiments of diaphragm pumps including a sensor mount are disclosed. In one illustrative embodiment, a diaphragm pump may include a shaft disposed within a pump housing and coupled to at least one diaphragm, a mount removably attached to the pump housing and having a sensor receptacle, and a proximity sensor received in the sensor receptacle of the mount such that a sensing end of the proximity sensor is flush with an end of the sensor receptacle nearest the shaft.

Diaphragm pump with sensor mount

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.

One piece diaphragm

Illustrative embodiments of diaphragm pumps including a muffler-mounted sensor are disclosed. In one illustrative embodiment, a diaphragm pump includes a shaft coupled to at least one diaphragm, an exhaust chamber configured to receive a motive fluid that has driven reciprocation of the at least one diaphragm and the shaft, a muffler disposed at least partially within the exhaust chamber, the muffler having a sensor mounting chamber defined therein, and a proximity sensor disposed in the sensor mounting chamber, a sensing end of the proximity sensor being flush with an end of the sensor mounting chamber nearest the shaft.
