<p>A head for a diaphragm pump comprising a flat annular base (3) or coupling to a body of the pump, the annular base (13) comprising a groove for receiving a rim of a diaphragm, and four seatings (2) comprising bores for mounting the pump on the body by means of bolts, a hemispheric chamber (4) rising from the flat annular base (3) which hemispheric chamber (4) constitutes a pumping chamber from which an aspirating conduit (41) and a discharge conduit (42) depart. A profiled external wall (5) departs from a top of the hemispheric chamber (4) and is connected to the flat annular base (3) in a direction by the body of the aspirating conduit (41) and the discharge conduit (42), and in a perpendicular direction thereto by two opposite rib structures (52) forming a single unit with the hemispheric chamber (4).</p> |
