Large range of materials for many applications available as a standard. Extended selection chart with additional pump sizes for small flow rates Easy to dismantle with forcing screws provided at the interface of casing cover and bearing bracket Product Information as per Regulation No. 547/12 (for Water Pumps with a Maximum Shaft Power of 1 kw) Implementing "Ecodesign" Directive 09/125/EC Minimum efficiency index: see data sheet The benchmark for most efficient water pumps is MEI Year of construction: see data sheet Manufacturer s name or trade mark, commercial registration number and place of manufacture: see data sheet or order documentation Product s type and size identificator: see data sheet Hydraulic pump efficiency (%) with trimmed impeller: see data sheet Pump performance curves, including efficiency characteristics: see documented characteristic curve The efficiency of a pump with a trimmed impeller is usually lower than that of a pump with full impeller diameter. Trimming of the impeller will adapt the pump to a fixed duty point, leading to reduced energy consumption. The minimum efficiency index (MEI) is based on the full impeller diameter. >Operation of this water pump with variable duty points may be more efficient and economic when controlled, for example, by the use of a variable speed drive that matches the pump duty to the system. Information relevant for disassembly, recycling or disposal at end of life: see installation/operating manual Information on benchmark efficiency or benchmark efficiency graph for MEI = 0.7 (0.4) for the pump based on the model shown in the Figure are available at: Etanorm 7
