• Performance Curve Specifications:
  • Tolerances according to ISO 9906 Annex A.
  • Curves refer to effective speed of asynchronous motors at 50 Hz.
  • Measurements were carried out with clean water at 20 °C and with a kinematic viscosity of ν = 1 mm²/s (1 cSt).
  • The NPSH curve is an average curve.
  • The continuous curves indicate the recommended working range. The dotted curve is only a guide.
  • Pumps should not be used at a flow rate below 10% of best efficiency point to avoid the risk of over-heating.
  • Minimum Efficiency Index (MEI) for all listed models is > 0.40.
