2CP. Centrifugal twin-impeller pumps

Transcription

1 CP Centrifugal twin-impeller pumps Clean water Domestic use Civil use Industrial use PERFORMANCE RANGE Flow rate up to l/min (7 m³/h) Head up to m APPLICATION LIMITS Manometric suction lift up to 7 m Liquid temperature between - C and +9 C Ambient temperature between - C and + C Max. working pressure bar ( bar for CP/3N) Continuous service S CONSTRUCTION AND SAFETY STANDARDS EN 33- EN 3- IEC 33- IEC 3- CEI - CEI -3 INSTALLATION AND USE Suitable for use with clean water and with liquids that are not chemically aggressive towards the materials from which the pump is made. The high performance and adaptability to a wide range of applications make them the ideal choice in domestic, civil and industrial applications, in particular for the distribution of water in combination with pressure tanks for boosting pressure in the network and for firefighting sets. The pump should be installed in an enclosed environment or sheltered from inclement weather.
