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 efficiency curves for MAGI series pumps:
•
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
efficiency 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)
BETA 2 25-60/180
BETA 2 25-60/130
BETA 2 25-40/180
The reference criterion for the most energy-efficient circulators is EEI ≤ 0.20. For the BETA 2 pump, EEI≤0.23,
this means that the BETA pump is an energy-saving pump

In order to protect the control panel and the pump stator against water steam condensation, always keep the temperature of the
heating medium higher than the ambient temperature.
