• Applicable Standard of Test: ISO 9906 – Annex A
• 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 temperature and with a kinematic viscosity of ν = 1 mm²/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.
  • To avoid the risk of overheating, pumps should not be used at a flow rate below 10% of the best efficiency point.
  • The minimum efficiency index (MEI) is a measure of the quality of a pump size in respect to its mean efficiency, based on hydraulic efficiency and head at the best efficiency point.
  • The efficiency of a pump with a trimmed impeller is usually lower than that of a pump with the full impeller diameter. The MEI is based on the full impeller diameter.
  • Operation of these water pumps with variable duty points may be more efficient and economic when controlled, for example, by the use of a variable speed drive that matches the pump duty to the system.
