Abstract (en)
[origin: EP2921705A1] A diaphragm-plate group for activating a diaphragm pump comprises: a circular membrane (3) made of an elastomer material for delimiting a pump chamber (2), and a circular plate (40) which is able to be moved in alternating motion for activating the membrane (3). The plate (40) is slightly convex with a convexity thereof facing towards the membrane (3), and the plate (40) exhibits, on a whole surface thereof facing towards the membrane (3) and destined to come into contact therewith, a series of lowered parts (42) for avoiding sticking of the membrane to the plate surface.
