1. A laminate membrane for membrane pumps, comprising:
an elastomer body configured as a circular plate that has a plate edge with a clamping surface, a bottom and a flexible membrane segment that connects the plate with the bottom and is turned up with each stroke movement of the bottom;
a contact layer applied to the elastomer body and made of polytetrafluoroethylene (PTFE); and
a barrier layer configured as a permeation barrier,
wherein the barrier layer is made of a perfluoroalkoxy copolymer (PFA) and is applied to a side of the contact layer that faces away from the elastomer body.
2. A laminate membrane according to claim 1, wherein the bottom of the elastomer body contains a vulcanized core having a connector device for a piston rod, or contains a central opening for connection to a piston rod.
3. A laminate membrane according to claim 1, wherein the elastomer body contains a textile reinforcement insert.
4. A laminate membrane for membrane pumps comprising:
an elastomer body configured as a circular plate that has a plate edge with a clamping surface, a bottom and a flexible membrane segment that connects the plate with the bottom and is turned up with each stroke movement of the bottom;
a product-side contact layer made of polytetrafluoroethylene (PTFE);
an intermediate layer made of polytetrafluoroethylene (PTFE) and abutting the elastomer body; and
a barrier layer configured as a permeation barrier disposed between the contact layer and the intermediate layer, wherein the barrier layer consists of a perfluoroalkoxy copolymer (PFA) and abuts against the product-side contact layer and the intermediate layer so that said product-side contact layer, said barrier layer and said intermediate layer form a three-layered structure of PTFEPFAPTFE on said elastomer body.
