Title (EN) DIAPHRAGM WITH EDGE SEAL
(FR) MEMBRANE AVEC JOINT D'ÉTANCHÉITÉ DE BORD
Abstract:
(EN) A diaphragm (18) includes a disk-shaped center planar portion (40) and a first lip (42) and a second lip (44) on the outermost edge of the disk shaped portion (40) and extending transversely to the planar disk portion (40). The first lip (42) is on a first side of the diaphragm (18) and the second lip (44) is on an opposite side of the diaphragm (18). A mounting portion (38) extends outward from the center of the face of the planar portion (40) on the first side of the diaphragm (18). For metering pump applications pumping harsh fluids, the diaphragm (18) is typically made from a fiuoropolymer and in particular may be made from polytetrafluoroethylene (PTFE).
(FR) L'invention concerne une membrane (18) qui comprend une portion plane (40) centrale en forme de disque et une première lèvre (42) ainsi qu'une deuxième lèvre (44) sur le bord le plus à l'extérieur de la portion (40) en forme de disque et qui s'étend transversalement par rapport à la portion plane (40) en forme de disque. La première lèvre (42) se trouve sur un premier côté de la membrane (18) et la deuxième lèvre (44) se trouve sur un côté opposé de la membrane (18). Une portion de montage (38) s'étend vers l'extérieur à partir du centre de la face de la portion plane (40) sur le premier côté de la membrane (18). Pour les applications de pompe de pompage qui pompent des fluides agressifs, la membrane (18) est généralement fabriquée à partir d'un fluoropolymère et peut notamment être fabriquée en polytétrafluoroéthylène (PTFE).
