EFFICIENCY CURVE

Efficiency curve guidance
Any pump setting will have a proper efficiency curve (Q / H curve). The AUTO (auto-adaptation) mode covers the
efficiency scope. The input power curve (P1 curve) belongs to each Q/H curve. The power curve represents the
pump power consumption (P1) in Watt for the given Q/H curve.
Conditions to obtain the curve
The description below regards
• Pumped medium: water without gas.
• The water density for which the curves were created was ρ= 983.2 kg / m3, temperature: + 60 °
• All values expressed with curves are means, they cannot be treated as guaranteed curves. If a specific
ef ficiency is required, carry out a separate measurement for the given pump.
• The curves were created using pumped water kinematic viscosity υ = 0,474 mm2 / s (0,474CcST)
The reference criterion for the most energy-efficient circulators is EEI ≤ 0.20. For the MAGI 2 pump, EEI≤0.23,
