Product Description
The variable speed pumps adapt the water flow rate to the system requirements, allowing,consequently, the energy consumption control and a better management of the plant.
In terms of efficiency, there are several reasons why variable speed pumps are undoubtedly beneficial.
Synchronous permanent magnet motors with minimum efficiency IE4
The Blulogica variable speed pumps are built with permanent magnet motors whose efficiency is significantly higher, IE4 at least, than the efficiency of the electric pumps that use standard squirrel cage induction motors (IE3 max in case of three-phase motors), so than, with the same working cycle, the absorbed power from a permanent magnet motor will be less than that the one absorbed by an induction motor.
Standard (IEC60034-30) Energy efficiency level for electric motors 2 poles 0,75Kw
The efficiency difference among a standard motor single-phase and one with permanent magnets can exceed 10%

Dynamic system management
Do to the centrifugal pumps operation principles a lower rotational speed leads to a reduction in power absorbed by the network, therefore, adapting the speed of the pump, through the ECOLINK system, to the functions required by the system, will allow the motor to absorb the minimum power necessary to provide the requested service, generatingsignificant energy savings.
