Uprated: Nicolini mark this power as one IEC does not list for the frame. It gives more power in a smaller frame, at lower efficiency.

Pumps rated at this motor's speed that need no more than 3 kW, where this is the smallest motor that does the job.

For an IEC 90 frame with a 24 mm shaft, bolting to the small flange (B14). Pick the one made for your pump series.
