Wilo Atmos PICO 25/1-4 circulation pump 4232691

Energy-efficient circulation pump Wilo Atmos PICO 25/1-4 180 with threaded connection, 220 V

Purpose

The highly efficient Wilo-Atmos PICO pump with electronically controlled wet rotor and threaded connection is used in all heating and air conditioning systems. The devices are maintenance-free. The synchronous electric motor, manufactured using ECM technology, is resistant to blocking currents. The pump has an integrated electronic speed control system for smooth regulation of the differential pressure.

The Wilo-Atmos PICO saves up to 90% of energy compared to a standard pump thanks to automatic regulation of the power consumption. To make the pump more accessible, the user interface and settings have been reduced to the necessary minimum – two operating modes and six curves. The pump is controlled by just one button.
