PRO-NGA Stainless steel pumps with open impeller PERFORMANCE RANGE INSTALLATION AND USE • • Suitable for use with clean water and liquids that are not chemically aggressive towards the materials from which the pump is made. The open impeller design allows liquids containing relatively high levels of impurities to be pumped without the risk of the impeller clogging. All of the components in contact with the pumped liquid are constructed in stainless steel AISI 316. As a result of these characteristics the PRO-NGA series pumps find specific use in assemblies for washing fruit, vegetables, fish and shellfish, in industrial assemblies for washing metallic objects and glass containers, as well as for the circulation of cooling liquids. The pump should be installed in an enclosed environment, or at least sheltered from inclement weather. Flow rate up to 350 l/min (21 m³/h) Head up to 20 m APPLICATION LIMITS • • • • • • Manometric suction lift up to 7 m Liquid temperature between -10 °C and +90 °C Ambient temperature between -10 °C and +40 °C Max. working pressure 6 bar Passage of suspended solids up to Ø 10 mm Continuous service S1 CONSTRUCTION AND SAFETY STANDARDS OPTIONALS AVAILABLE ON REQUEST EN 60034-1 IEC 60034-1 CEI 2-3 • • CERTIFICATIONS GUARANTEE Special mechanical seal Other voltages or 60 Hz frequency 2 years subject to terms and conditions 70
