PERFORMANCE CURVE SPECIFICATIONS V4 PERFORMANCE CURVE SPECIFICATIONS The specifications below qualify the curves shown on the following pages. Tolerances according to ISO 9906 Annex A The curves refer to effective speed of asynchronous motors at Measurements were carried out with clean water at 20 C of temperature and with a kinematic viscosity of = mm 2 /s ( cst) The NPSH curve is an average curve obtained in the same conditions of performance curves. The continuous curves indicate the recommended working range. The dotted curve is only a guide. In order to avoid the risk of over-heating, the pumps should not be used at a flow rate below 0% of best efficiency point. Symbols explanation: Q = volume flow rate H = total head P 2 = pump power input (shaft power) = pump efficiency NPSH = net positive suction head required by the pump MEI = minimum efficiency index The minimun efficiency index (MEI) is a measure of the quality of a pump size in respect to its mean efficiency. The minimum efficiency index is based on the hydraulic efficiency and on the head at the best efficiency point. The efficiency of a pump with trimmed impeller is usually lower than that of a pump with the full impeller diameter. The 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. The operation of these water pumps with variabile duty points may be more efficient end economic when controlled, for example, by the use of a variable speed drive that matches the pump duty to the system. 200
