Azmec was established in Genoa in 1960, as a company specialising in machining for third parties. In 1964, it began manufacturing vacuum pumps and liquid ring compressors. In 1988, after selling its shareholding, the company expanded its aims, investing in new markets. In 1998, the new premises in Verderio were completed to become the new home for all production and design of liquid ring vacuum pumps using state-of-the-art technology and 2D and 3D software.

In 2018 the move was completed from Voltri, Genoa to Arenzano to a larger, recently completed factory building. In 2022, Azmec completed its acquisition of RIVA TECNOIMPIANTI SRL, a company specialising in making metal carpentry components and hydraulic power units.
