Wilo YONOS PICO1.0 25/1-8-130 circulating pump

The Wilo YONOS PICO1.0 25/1-8-130 circulator pump (reference: 4248087) is a highly efficient and state-of-the-art solution for heating and air conditioning systems. This maintenance-free wet rotor pump is equipped with advanced technology and a robust design that ensures reliable and efficient operation for many years, making it ideal for both residential and commercial applications.

The high-efficiency EC motor is one of the main attributes of this pump. This motor is not only block-resistant, but it is also accompanied by an electronic control system that continuously adjusts the pump's power according to the system's needs, thus optimizing energy consumption. With an energy efficiency index (EEI) ≤ 0.23, the Wilo YONOS PICO1.0 is a pump that meets the highest energy efficiency standards, contributing to reduced energy consumption and operational costs over time.

The system allows for the selection of different control modes to adapt to the specific application, whether it be a underfloor heating system or radiators. The two main control modes are:

• Constant differential pressure (Δp-c): Maintains a constant pressure, ideal for systems with stable demand.
• Variable differential pressure (Δp-v): Adjusts the pressure according to variations in system demand, improving efficiency in applications with fluctuations.

The integrated LED indicator provides key information about the pump's operation. You can visualize the head height during adjustment, the current power consumption in watts, and possible fault indications through error codes, making system management and maintenance easier. It also includes a purge function that can be manually activated to remove air from the motor compartment, improving performance and preventing operational issues.

Thanks to its robust design, the pump is protected against electromagnetic interference according to EN 61800-3 standards, and features an integrated motor protection to prevent overheating and other damage. Additionally, the pump has an automatic unlocking function, which facilitates maintenance and ensures that the pump continues to operate optimally.

The material of the pump housing is gray cast iron, while the impeller is made of PP-GF40, a strong and durable material. The shaft is made of stainless steel, ensuring corrosion resistance and long-term durability. The bearings are made of metal-impregnated carbon, providing smooth and quiet operation.

Regarding hydraulic specifications, the maximum head height is 7.6 meters and the maximum flow rate is 4.4 m³/h, ensuring powerful and consistent performance even in more demanding systems. Additionally, it supports a maximum working pressure of 10 bar.

The pump is easy to install thanks to its thread length of 130 mm and G 1½ threaded connections, making it compatible with a variety of systems. Its IPX4D protection ensures that it is protected against water splashes, making it an ideal option for humid or challenging environments.
