Abstract
A diaphragm pump including at least one diaphragm having an inner diaphragm surface, an outer diaphragm surface, and a projecting rim, the rim projecting from the inner diaphragm surface and having an inner circumferential surface and an outer circumferential surface, a hub positioned to lie within the inner circumferential surface of the projecting rim, a ring positioned around the outer circumferential surface of the projecting rim, where the hub and ring secure the projecting rim there between, and a reciprocating rod coupled to at least one of the hub and the ring.
Claims38
A method of assembling a diaphragm pump, the method comprising:
- providing a diaphragm including a substantially orthogonal rim projecting from the diaphragm, the rim having an inner circumferential surface and an outer circumferential surface;
- inserting a hub into the rim to engage the inner circumferential surface;
- inserting a ring over the rim to engage the outer circumferential surface;
- coupling a reciprocating rod with the hub;
- and
- pinching the ring between the hub and a shoulder adjacent an end of the rod.

A diaphragm pump comprising:
- at least one diaphragm having an inner diaphragm surface, an outer diaphragm surface, and a projecting rim, the rim projecting from the inner diaphragm surface and having an inner circumferential surface and an outer circumferential surface;
- a hub positioned to lie within the inner circumferential surface of the projecting rim;
- a ring positioned around the outer circumferential surface of the projecting rim, wherein the hub and ring secure the projecting rim there between;
- and
- a reciprocating rod coupled to at least one of the hub and the ring;
- wherein the inner circumferential surface forms an acute angle with the inner diaphragm surface.

A diaphragm pump comprising:
- at least one diaphragm having an inner diaphragm surface, an outer diaphragm surface, and a projecting rim, the rim projecting from the inner diaphragm surface and having an inner circumferential surface and an outer circumferential surface;
- a hub positioned to lie within the inner circumferential surface of the projecting rim;
- a ring positioned around the outer circumferential surface of the projecting rim, wherein the hub and ring secure the projecting rim there between;
- and
- a reciprocating rod coupled to at least one of the hub and the ring;
- wherein the rim includes a base portion coupled to the inner diaphragm surface and a distal portion, the distal portion having a larger thickness than the base portion;
- wherein the rim includes a proximal portion between the base portion and distal portion, the proximal portion having a larger thickness than the base portion and a smaller thickness than the distal portion.

A diaphragm pump comprising:
- a diaphragm having a tapered projecting rim projecting from an inner surface of the diaphragm;
- a tapered hub having a circumferential outer surface mating with the tapered projecting rim;
- a reciprocating rod coupled to the hub;
- and
- a ring coupled to the rod and positioned around the projecting rim;
- wherein the rod includes a shoulder adjacent an end of the rod, and wherein the ring is pinched between the shoulder and the hub.
3 more elements
A diaphragm pump comprising:
- a diaphragm having a projecting rim, the rim defining a base portion coupled to the diaphragm and a distal portion, the distal portion having a larger thickness than the base portion;
- a hub having a first end and a second end, the hub tapering from the first end to the second end, the first end being adjacent to the base portion of the rim and the second end being adjacent to the distal portion of the rim;
- a ring engaging an outer circumferential surface of the rim, such that the projecting rim is pinched between the hub and the ring;
- and
- a reciprocating rod coupled to the hub, wherein the ring is secured to the hub between the rod and the hub.
