• Performance Curve Specifications:
  • Tolerances according to ISO 9906:2012 - Grade 3B.
  • Curves refer to effective speed of asynchronous motors at 50 Hz, 2 poles.
  • Measurements were carried out with clean water at 20 °C and with a kinematic viscosity of ν = 1 mm²/s (1 cSt).
  • NPSH curve is an average curve obtained in the same conditions of performance curves.
  • Continuous curves indicate the recommended working range; dotted curves are a guide.
  • Symbols: Q = volume flow rate, H = total head, P₂ = pump power input (shaft power), η = pump efficiency, NPSH = net positive suction head required by the pump.
• Thermal Insulation: Insulation of the pump casing is available ON REQUEST.
• Dimensions and Weight: Detailed tables for pump dimensions and weights are available in the official PDF (pages 400-401).
