Electronic circulation pumps EVOSTA2 SOL with a synchronous permanent-magnet motor and  frequency converter, designed for solar systems. This 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. All models have a single sequential  control button, 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. A version controlled by an external PWM signal is available (1.5 m power cable).
