Performance Curve 

Following conditions are suitable for the performance curves shown bellow:

1. All curves are based on the measured values of 50Hz: constant motor speed 2900rpm or 2950rpm.

2. Curve tolerance in conformity with 1SO9006 Annex A.

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

4. The operation of pump shall refer to the performance region indicated by the thickened curve to prevent overheating due to too small flow rate or overload of motor due to too large flow rate.
