PERFORMANCE 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 60 Hz
Measurements were carried out with clean water at 20°C of temperature and with a kinematic viscosity

of  = 1 mm
/s (1 cSt)
The NPSH curve is an average curve obtained in the same conditions of performance curves.
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 best
efficiency point.
Symbols explanation:
Q = volume flow rate
H = total head
P = pump power input (shaft power)

 = pump efficiency
NPSH = net positive suction head required by the pump
