Azmec was established in Genoa in 1960, as a company specialising in machining for third parties. In 1964 Azmec began manufacturing vacuum pumps and liquid ring compressors for the paper/making industry, working almost exclusively at national level, standing out for the quality of its machines. In 1988 the company stock was sold to a group already operating in the pump industry and the company expanded its objectives from a technical and commercial viewpoint, by investing in new markets in the chemical, petrochemical, steel, tannery, pharmaceutical, textile, food, sugar, cellulose, cement, synthetic leather, and plastics sectors.
In 2018 it completed its move from Voltri, Genoa to Arenzano, to a larger, recently completed factory building, and now Azmec works from a production unit in Arenzano, province of Genoa, as well as from Verderio, in the province of Lecco. This latter was opened in 1993 and then expanded in 1998, designing and manufacturing liquid ring vacuum pumps using the most cutting-edge technologies and dedicated 2D and 3D software.
