Circulation Pump Wilo Yonos PICO 25/1-8 (Single-phase)

Quantity

Wilo Yonos PICO 25/1-8 is a high-efficiency electronically controlled circulation pump designed for heating and air-conditioning systems. Thanks to its ECM technology synchronous motor and electronic control, the pump provides precise system pressure regulation. The threaded connection allows for quick and easy installation. The pump offers flexible operating modes, including variable and constant differential pressure control and three constant-speed settings, making it suitable for both underfloor heating and conventional radiator heating systems. With a maximum head of 7.6 m, maximum flow rate of 4.4 m³/h, and an EEI ≤ 0.23 energy efficiency index, it provides an efficient and reliable solution for modern heating systems
