Circulation pump DAB EVOSTA2 40-70/130 mm

The DAB EVOSTA2 40-70/130 mm is a modern electronic circulation pump with ultra-low energy consumption, designed for circulating heat-transfer fluid in all types of residential heating, cooling and air-conditioning systems. It is an ideal solution both for new installations and for replacing old three-speed pumps thanks to its compact body and easy connection.

Advantages of the EVOSTA2 series:

The new DAB EVOSTA2 line combines the reliability of traditional mechanical pumps with the advanced features of electronic control.
A synchronous motor with a permanent magnet, an integrated frequency converter and an energy-efficiency level of EEI ≤ 0,18 significantly reduce electricity consumption while maintaining full performance.

With IPX5 protection, an integrated air-release valve and highly reliable construction, EVOSTA2 stands out for its long service life and operating stability.

An additional benefit is the innovative anti-clogging system, which prevents limescale and dirt buildup, protects the motor from blockage during startup, and ensures smooth, continuous circulation throughout its lifetime.
