Since Grupo Industrial Ercole Marelli SA's beginnings in 1963 at Illescas, Toledo, Spain, the Marelli Group's founding goal has been to create a Spanish industry for centrifugal pumps developed under high customer requirements.

Marelli has two main facilities at Illescas and Cedillo in Spain, and another one located in Morocco. It also incorporates a specialised company focusing on the latest technology in engineered pumping: Bombas Ercole Marelli.

The company's four economic years since 2002 represented a period of high growth in product and economic figures, reinforced by Marelli's company strategy, called Investment for Growing.
