Specific electrical parameters (Nominal power P2, Absorbed power P1, Voltage, Current, Capacitor) are detailed in the performance tables for each model series (Multi EVO-A 3, 5, and 8).
Mechanical / hydraulic
The pumps are self-priming multi-stage centrifugal horizontal pumps. Hydraulic performance is according to ISO 9906:2012 - Grade 3B. Hydraulic performance curves (Q vs. H and efficiency) are available in the official PDF for Multi EVO-A 3, 5, and 8 series. Performance tables detailing flow rates (Q in l/min and m³/h) and total head (H in water column metres) for specific models are also provided.
