Wilo Yonos PICO circulation pump 25/1-6 130 mm

The Wilo Yonos PICO is an IPX4D-rated circulation pump that ensures continuous water movement within a closed system, such as a central heating installation or underfloor heating. Equipped with an LED control panel that allows easy adjustment of the desired setting in 0.1 m increments, the PICO circulation pump provides the ideal solution for efficient and reliable water circulation.

Advantages and features

IPX4D rating: The IPX4D classification guarantees the pump is protected against splashing water from all directions, ensuring safe operation in damp installation environments.
≤0.20 Energy Efficiency Index: The pump ranks among the most energy-efficient circulation pumps on the market, compliant with the ErP directive, resulting in lower energy costs.
Integrated motor protection: Automatic protection against overload and blockage, providing maximum operational reliability and extending the pump’s service life.
Automatic unblock function: Prevents rotor seizure after standstill and ensures reliable, low-maintenance operation of the pump.
Manual venting function: Easily vents the rotor chamber for quiet, trouble-free operation without air entrapment.

Applications and usage

The Wilo Yonos PICO 25/1-6 130 mm is versatile, suitable for both new builds and renovation projects. The pump is ideal for use in detached houses, apartments, and smaller commercial buildings where efficient and reliable circulation of heating water is required. The circulation pump can be applied in various heating systems, such as:

Central heating systems: For circulating warm water to radiators or convectors.
Underfloor heating systems: For even heat distribution at low flow temperatures.
Heat pump circuits: Suitable as a circulation pump between the heat pump and buffer tank, or in the secondary distribution circuit of a heat pump system.
