High energy-efficient electronically operated recirculation pump that meets the requirements of energy class "A". The E-IBO 15-14 pump is designed for continuous operation aimed at recirculating hot water and small heating systems. It can be used in ventilation and air conditioning systems. By using this recirculation pump, significant water savings can be achieved. Compared to traditional circulation pumps, due to the use of a permanent magnet in the rotor, the energy consumption of the E-IBO pump is very low, reaching up to 3 W, depending on the installation. The pump is equipped with a spherical working rotor at various levels.
