The specifications below qualify the curves shown on the following pages.

Tolerances according to ISO 9906:2012The curves refer to effective speed of asynchronous motors at 60 HzMeasurements were carried out with clean water at 20°C of temperature and with a kinematic viscosityof ν = 1 mm2/s (1 cSt) 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 10% of bestefficiency point.
