Wilo Yonos PICO Circulation Pump 25/1-4 130 mm

The Wilo Yonos PICO is an IPX4D-rated circulation pump designed to keep water continuously moving 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 increments of 0.1 m, the PICO circulation pump offers the ideal solution for efficient and reliable water circulation.

Benefits and Features

IPX4D Rating: The IPX4D classification ensures the pump is protected against splashing water from all directions, guaranteeing safe operation in humid installation environments.
Energy Efficiency Index ≤0.18: This pump exceeds the ErP directive requirements and ranks among the most energy-efficient circulation pumps in its power category.
Integrated Motor Protection: Provides automatic protection against overload and blockage, ensuring maximum operational reliability and extending the pump's service life.
Automatic Unblocking Function: Prevents rotor seizure after standstill, ensuring dependable, low-maintenance operation of the pump.
Manual Venting Function: Simplifies venting of the rotor chamber for quiet, trouble-free operation without air entrapment.

Applications and Usage

The Wilo Yonos PICO 25/1-4 130 mm is versatile and suitable for both new build and refurbishment projects. The pump is ideal for larger residential properties and multi-storey buildings where efficient and reliable circulation of heating water is essential. It can be used in various heating systems, including:

Central Heating Systems: For circulating warm water to radiators or convectors.
Underfloor Heating Systems: Ensures even heat distribution at low supply temperatures.
Heat Pump Circuits: Suitable as a circulation pump between the heat pump and buffer tank, or within the secondary distribution circuit of a heat pump system.
