Wilo-Yonos PICO 1.0 Universal Circulation Pump – Efficiency and User Comfort

The Wilo-Yonos PICO 1.0 25/1-4-130 circulation pump is a modern solution for heating and air conditioning systems, combining high energy efficiency with ease of use. Designed for both professional installers and end-users, it provides reliable operation and optimal performance parameters. Equipped with an ECM synchronous motor resistant to blocked current, it guarantees long-term operation without the risk of damage.

Design and Application

The pump is intended for circulating clean water in closed heating and air conditioning systems. Its compact design facilitates installation even in tight spaces, and the easily accessible control panel allows for quick configuration of operating parameters. The use of high-quality materials, such as gray cast iron (GG 20) in the pump body and polypropylene (PP-GF) in the impeller, ensures durability and corrosion resistance. Threaded connections with a diameter of 1 ½ inches (40 mm) allow for easy connection to the existing installation.

Advantages and Benefits

• High energy efficiency: Thanks to the EC motor and integrated control system, the pump achieves an energy efficiency index EEI ≤ 0.20, which translates to lower electricity bills.
• Intuitive operation: The “green knob” allows easy setting of the pump operating mode – constant or variable differential pressure – adapting it to the specifics of the installation (radiators or underfloor heating).
• Precise adjustment: The ability to precisely adjust the head in increments of 0.1 m allows for optimal adaptation of the pump to the needs of the heating system.
• Built-in diagnostic functions: A clear LED display informs about current energy consumption, head and any failures (error codes).
• Automatic impeller unblocking: The automatic impeller unblocking function prevents it from blocking in the event of a long pump standstill.
• Easy installation: The compact design, easy access to mounting screws and the Wilo-Connector plug facilitate pump installation and servicing.
• Wide operating temperature range: The pump can operate in an ambient temperature range of -10°C to 40°C and a fluid temperature range of -10°C to 95°C.
• Maximum working pressure: 10 bar ensures safe operation in standard central heating installations.

The Wilo-Yonos PICO 1.0 pump is an investment in comfort and savings – a reliable solution for every home and building.
