  • Bracket: Cast iron - aluminium.
• Performance Range:
  • Tolerances are according to ISO 9006:2012 - Grade 3B.
  • Performance curves refer to effective speed of asynchronous motors at 50 Hz, 4 poles.
  • Measurements were conducted with clean water at 20 °C and a kinematic viscosity of v = 1 mm²/s (1 cSt).
  • The NPSH curve is an average; a safety margin of at least 1 m should be considered during pump selection.
  • Pumps should not be operated at a flow rate below 10% of the best efficiency point to prevent overheating.
  • Symbols: Q = volume flow rate, H = total head, P2 = pump power input (shaft power), ƞ = pump efficiency, NPSH = net positive suction head required by the pump.
  • Detailed performance data, including flow rates, total manometric head, and motor power (kW/HP), are available in selection charts and performance curves for various pump models and impeller diameters. See the official PDF (pages 204-221) for exact tabulated values and performance curves.
