Performance curve:


All performance curves are based on the measured values when a motor works under power of 380V, at a constant speed of 2900r/min.
The capability of flow and head conforms to ISO9001.
Measurement is done in 20oC air-free water of which viscosity is 1mm2/s.

The operation of pump shall refer to the performance range marked in thickened curve so as to avoid damages caused by over-load.
