Pump membrane for diaphragm pump

A pump membrane for a diaphragm pump comprising:

• an elastic body composed of a rubber material and shaped as a plate, the elastic body having a peripheral clamping edge configured for fastening with the diaphragm pump;
• a core composed of a thermoplastic material and at least partially embedded into the elastic body;
• and
• a connection member configured for operatively connecting with a drive rod of the diaphragm pump;
• wherein, during production of the diaphragm pump, the rubber material of the elastic body is vulcanized on the thermoplastic material of the core such the rubber material and the thermoplastic material are covalently cross linked at a boundary layer formed between the elastic body and the core, and
• wherein the thermoplastic material and the rubber material are selected such that the thermoplastic material and the rubber material are covalently cross-linked with one another at the boundary layer free of adhesive.

• a core composed of a thermoplastic material and at least partially embedded into the elastic body;
• a peg extending upwardly from a surface of the core;
• and
• a connection member arranged at an end of the peg away from the surface of the core, the connection member configured for operatively connecting with a drive rod of the diaphragm pump;
• wherein, during production of the diaphragm pump, the rubber material of the elastic body is vulcanized on the thermoplastic material of the core such the rubber material and the thermoplastic material are covalently cross linked at a boundary layer formed between the elastic body and the core.
