A "Leader" ofPumps for IndustryGruppo AturiaAUDOLI &BERTOLAARISCHIAPPA

A LONG HISTORY RICH OF IMPORTANT EXPERIENCES1927: Aturia starts its activity in Milano, operating in the field of centrifugal water pumps.1946: The availability of electric power and underground water in the Milano area givesAturia the opportunity to develop the submersible pumpsets.1960: Aturia improves the performance and the reliability of the submersible pumpsets andextends its market area from Italy to Mediterranean Countries, America, Asia.1990: With the aim of enlarging the production range, Aturia takes over the pumpsbusiness of “Rotos” and “Marelli”.2003: Acquires "Audoli & Bertola".2006: Aturia, in order to achieve more competence and to gain experience in highdemanding applications (Chemical, Petrochemical, Nuclear), acquires "Gruppe Rutschi".Rutschi, the "Pioneer" of Canned Motor Pumps, operates with two companies:Rutschi Fluid AG in Brugg (Switzerland) and Pompes Rutschi SA in Mulhouse(France).2009: Acquires the pump business of “Aris-Chiappa”.Gruppo Aturia: HISTORYAUDOLI &BERTOLAARISCHIAPPA1919: Rotos starts the production of electric motors, monobloc, single, multistage andvertical pumps in Milano. The company develops all water applications in the field ofagriculture, building and industry.1962: Rotos joins "Guinard Group" and becomes the “Development Center” of multistagepumps for the French Group. Gaining the Guinard experience, Rotos starts theproduction of cast steel pumps for the process industry (ISO 2858 and API 610).1978: The company moves to the plant located in Pozzo d’Adda (Milano).1980: Rotos enters the “Marelli Group”.2005: Start up of the Plant in Taglio di Po (Rovigo) dedicated to the Developmentand Production of Magnetic Drive Sealless Pumps.1891: Marelli is founded in Sesto San Giovanni (Milano).1898: It starts the production of electric motors.1905: Marelli starts the production of centrifugal pumps coupled to electric motors anddevelops different types of pumps for various applications: from agriculture to navy,from tool machines to chemical industries.1979: The monobloc pumpsets business is transferred to "Ercole Marelli Componenti" (EMC)and the business of vertical pumps with large flows and split case pumps aretransferred to the Engineering Company "Impianti Tecnologici Ercole Marelli" (ITEM).1984: GIEM (Gruppo Industriale Ercole Marelli) controls EMC,ITEM and ROTOS.1990: All pump activities of GIEM are transferred to "Gruppo Aturia".1890: Audoli & Bertola starts in Torino the production of vertical pumps for agriculture application.In the following years Audoli & Bertola develops the supply of "turn-keys" waterdistribution plants both in Italy and in other Mediterranean countries.1993: The "Gruppe Rutschi" acquires the company and improves the design of verticalpumps for heavy industrial applications (steel mills, cooling systems, power plants,marine) and Fire Fighting systems.2003: "Gruppo Aturia", in order to improve its presence in the industrial field,acquires "Audoli & Bertola". During the year the activities on the vertical pumps aremoved to Gessate (Milano), whilst the Fire Fighting business remains in Torino.1921: G.Chiappa Fonderie is set up in Torino and starts the production of castingsin bronze, aluminium and cast iron.1940: The company starts the production of centrifugal pumps for industrial applications1950: The name of the company is changed in A.R.I.S. (Acquedotti Ricerche Idriche Sottosuolo)1954: The company changes the name in Aris Chiappa1970: Aris Chiappa starts the production of vertical turbine pumps.In co-operation with gas turbine manufacturers (Fiat Avio, Nuovo Pignone) developsa range of lube oil pumps.2009: "Gruppo Aturia", with the aim to increase its production program in the Industrysector acquires the pump business of “Aris Chiappa”.

APPLICATIONSThe installation of submersible electric pumps,for more than 60 years, has allowedGruppo Aturia to acquire countless appliedexperiences in practically all fields in whichthese pumps are required.Submersible pumps, simply born to lift wellwater, have first replaceddeep well vertical pumps.Through the use of different materials suchas bronze, cast stainless steel and Duplexthey are now successfully used in heavyapplications where a high reliability is required,such as Mine, Off-Shore, Industry, Navy.The installation of submersible pumps insuitable vertical or horizontal cylindrical tanksallows silent- operating pressure liftingsystems in a more reduced space comparedto the traditional solutions with surface pumps.In order to offer customers hydrauliccharacteristics with best efficiency, the widerange of capacities and heads is covered byover five hundred types of submersiblepumpsets.In the last years, adopting a new design,Aturia has introduced a range ofmotors suitable for hot waters.
