  • Publication number: 20220099082
    Abstract: A diaphragm for a pump has a one-piece elastomeric body centered on an axis and formed with an annular outer clamping edge, an annular flexible web extending radially inward from the outer edge, and a core joined by the web to the outer edge and formed in turn by an upper wall and a lower wall axially spaced therefrom. This lower wall is formed on the axis with a throughgoing hole. An insert between the walls extends through the hole, and interengaging formations on the insert and on the lower wall radially couple the insert to the lower wall at an inner edge of the hole.

  • Patent number: 6923108
    Abstract: A composite diaphragm for diaphragm pumps comprises an elastomer body and a polytetrafluoroethylene (PTFE) coating on its back side. The elastomer body has a shape of a circular dish that has an edge region with a clamping area, a bottom and a flexible section of the diaphragm that connects the edge of the dish with the bottom. The flexible section of the diaphragm comprises a multitude of naps forming elevations on the elastomer backside of the elastomer body. The PTFE coating is a plane ring surface with the area of the flexible section of the diaphragm.
