CP Centrifugal pumps 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. As a result of their reliability and the fact that they are easy to use, these pumps are widely used in civil, agricultural and industrial applications such as for supplying water, in conditioning and cooling systems, for irrigation, etc. The pump should be installed in an enclosed environment, or at least sheltered from inclement weather. Flow rate up to 900 l/min (54 m³/h) Head up to 74 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 10 bar Continuous service S1 PATENTS - TRADE MARKS - MODELS • Registered Italian model n° 72753 for CP 220, CP 230, CP250 CONSTRUCTION AND SAFETY STANDARDS EN 60034-1 IEC 60034-1 CEI 2-3 CERTIFICATIONS OPTIONALS AVAILABLE ON REQUEST • • • • Special mechanical seal EN 10088-3 - 1.4401 (AISI 316) stainless steel motor shaft for CP 220, CP 230, CP250 Other voltages or 60 Hz frequency IP55 class protection for CP 220, CP 230, CP250 GUARANTEE 2 years subject to terms and conditions 44
