Circulation pump WILO Yonos PICO1.0 25/1-8 180, DN 25, 4248086
Wilo-Yonos PICO1.0 25/1-8 circulation pump, DN25, 180 mm
Wilo-Yonos PICO1.0 25/1-8 is a high-efficiency wet-rotor circulation pump with integrated electronic power control. It is designed for hot water heating systems, air-conditioning systems and other circulation applications where reliable, stable and energy-efficient water circulation is required.
The pump is equipped with an EC motor, electronic control and continuously variable differential pressure regulation. Two control modes are available: constant differential pressure Δp-c and variable differential pressure Δp-v, allowing the pump to be adapted for radiator heating or underfloor heating systems.
The LED display shows the set delivery head, current power consumption in watts, fault codes and the air venting function status. The pump includes a manual air venting function, automatic deblocking, integrated motor protection and quick electrical connection via Wilo-Connector.
