SUBMERSIBLE PUMPS Gruppo Aturia started developing the Submersible Pump for pumping water in agriculture and for distribution of water in the municipalities. For these applications all the structural parts of the pumps are made of Grey Cast Iron. Grey Cast Iron is a perfect material for clean and deep water, with good resistance to water corrosion. Gruppo Aturia, in the 70s developed a series of Mixed-flow and Radial-flow pumps fully in Bronze, to extend the applications of the Submersible Pumps to brackish, volcanic and sea waters. Bronze material, easy to cast, has excellent resistance to...

PRODUCTION INCLUDES The present range is manufactured for well diameters from 6” to 25”. • The hydraulical design has been oriented to obtain the maximum efficiencies and a stable Q / H performance curve. • In order to optimize the pump life the mechanical design limited the number of wear and tear components. • The impellers are dynamically balanced and splined to the shaft with entrainment key. • The shafts are driven by coaxial bearing bushes and fully protected by sleeves to ease disassembling. • All the pumps are provided with a build-in non-return valve, threaded and/or flanged, and...

REWINDABLE SUBMERSIBLE MOTORS In the Forties Gruppo Aturia started manufacturing electric submersible motors, worldwide patented. The present production is therefore the result of more than 60 years of research and development. CONSTRUCTION Asynchronous, three-phases Motor • Winding: it is made with copper wire coated by a thermoplastic insulating material with high dielectric properties, suitable for operating in water. • Rotor: squirrel cage type, dynamically balanced to guarantee regular operations without vibrations. • Stator: external casing in stainless steel. Stator slots are open...

SELECTION How to select a submersible pumpset In order to correctly select the pump and the materials to be used, it is necessary to consider of the following fac­ ors: t Water characteristics : - Type of water (potable, salty, indu­ strial, thermal, etc.) - Sand contents in PPM [g/m³] - Temperature in °C - pH (acidity or alkanity value) Well type: - Type of well (bored, artesian, tank) - Depth in [m or ft]. - Internal diameter at point where pump will be installed. Use: - Free discharge at ground level - Discharge into an elevated tank - Discharge into a pressure tank - Sprinkler...
