Performance Curves and Data (HS=0 m)
Performance curves illustrate the relationship between head (H) and flow rate (Q) for various MK pump models at 60 Hz. The table provides detailed performance data including flow rate (Q) in m³/h and l/min, and head (H) in meters, for different pump types and power ratings.
Note: Performance tolerances are according to EN ISO 9906 Grade 3B.
