The power curve presents the input power of each stage, which is divided into integrate impeller type (1/1) and the type with small impeller (2/3)

Pump Q-H curve, the thickened line presents recomendedperformance region

Eta curve presents efficiency of the pump. For the pump equipped with small impeller, its efficiency will be 2% lower than that shown by the curve.

NPSH curve expresses the average value of all curves of this series. A safety margin of 0.5m shall be taken into consideration when making selection.

Following conditions are applied to the performance curves shown in this catalogue:1. All the performance curves are based on the

measured values of a motor at a constant speed of 2900 min-1 for 50Hz and 3500 min-1 for 60Hz.

2.Curve tolerance in conformity with ISO9906, appendix A.

3. Measurement is done with 20℃ air-free water, kinematic viscosity of 1mm2 /sec.

4. The operat ion of pump shal l re fer to the performance region indicated by the solid line to prevent overheating due to too small flow rate or overload of motor due to too large flow rate.
