Stand mounted pump

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.

Diaphragm pump

A pump configured to move fluid from one location to another location is provided. The pump includes a pump housing. The pump housing is composed of a wall structure. The wall structure includes a first laminar portion of a thickness of the wall structure composed of a resin that does not include any reinforcing fibers. The wall structure also includes a second laminar portion of the thickness of the wall structure that is composed a resin with reinforcing fibers dispersed through the resin.

Filled resin layer separated pump housing

A diaphragm for use in a pump is provided. The diaphragm includes a flexible disc-shaped body having a first surface and an outer edge. The flexible disc-shaped body is made of an elastomer material. The fabric is applied on the first surface of the flexible disc-shaped body. And the fabric is composed of woven aramid based fibers.

Abrasion and puncture resistant diaphragm

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.
