Electronic circulation pumps EVOSTA3 with a synchronous permanent-magnet motor and frequency converter, designed for  heating and air-conditioning systems. The EVOSTA3 range of circulation pumps ensures high efficiency in all applications and brings  significant energy savings. The pump includes an electronic device for detecting pressure changes in the system and automatically adapts its output,  which ensures maximum efficiency with minimal energy consumption. The circulation pump EVOSTA 3 is also suitable for replacing old  three-speed circulation pumps, as it has the same overall length and connection. All models have an air-vent plug and  allow manual release of the motor shaft. The cast-iron body has a cataphoretic coating, the casing is made of stainless steel. Waterproof electronics with  IPX5 protection class.

EVOSTA3 has a display showing the selected operating mode, speed level, instantaneous power  consumption, instantaneous head and flow rate. Thanks to the new standard, the EVOSTA3  connector is interchangeable with connectors from other brands without the need for a new  electrical connection.
