Performance

• Applicable Standard of Test: ISO 9006:2012 - Grade 3B
• Test Conditions: Curves refer to effective speed of asynchronous motors at 60 Hz, 2 poles. Measurements were carried out with clean water at 20 °C temperature and with a kinematic viscosity of ν = 1 mm²/s (1 cSt).
• Operating Range: Continuous curves indicate the recommended working range. The dotted curve is for guidance only. To prevent overheating, pumps should not be used at a flow rate below 10% of the best efficiency point.
• Performance Range and Selection Chart: Performance data including capacity (l/min, m³/h) and total manometric head (m) are tabulated for various models. See the official PDF for exact tabulated values and performance curves.
