SELECTION CHART
Curve specifications
The specifications below qualify the curves shown on the following pages.
Tolerances according to ISO 9906 Annex A
The curves refer to effective speed of asynchronous motors at 50 Hz
Measurements were carried out with clean water at 20°C of temperature and with
a kinematic viscosity of n = 1 mm2/s (1 cSt)
In order to avoid the risk of over-heating, the pumps should not be used at a
flow rate below 10% of best efficiency point.
Symbols explanation:
Q = volume flow rate
H = total head
