Wilo Yonos PICO1.0 25/1-4 circulating pump

The Wilo Yonos PICO1.0 25/1-4 circulator pump, reference 4248082, is a high-efficiency pump designed for heating and air conditioning systems in residential and commercial applications. With an advanced EC motor and electronic control, it offers optimal and efficient performance, adapting to the specific needs of each installation. This model is distinguished by its maintenance-free design, making it an ideal solution for radiator or underfloor heating systems.

Electronic control and adjustment modes:
The Wilo Yonos PICO1.0 allows users to adjust the pump according to the specific requirements of the installation, thanks to its preselectable control modes. Users can choose between two control modes:

1. Constant differential pressure (Δp-c): ideal for maintaining a constant pressure throughout the system, ensuring efficient and stable operation.
2. Variable differential pressure (Δp-v): automatically adjusts the pressure based on system demand, optimizing energy consumption and reducing wear on components.

These control modes ensure that the pump always operates optimally, adapting to changes in the heating or air conditioning system load.

LED indicator and advanced functions:
One of the strengths of the Wilo Yonos PICO1.0 25/1-4 is its integrated LED indicator, which provides real-time information about the pump's performance. This indicator displays the head height during adjustment, the current energy consumption in watts, and, in case of faults, provides error codes that facilitate troubleshooting. This allows users and technicians to make precise adjustments and ensure the proper functioning of the system.

Additionally, the pump includes a manual purge function, which helps remove air from the motor compartment, improving operational efficiency and extending the equipment's lifespan. The automatic unlocking function is also an important feature that prevents the motor from locking up in adverse situations, keeping the system running continuously.

High-efficiency EC motor:
The EC motor (electronically commutated) of the Wilo Yonos PICO1.0 is designed to be highly efficient, with an energy efficiency index (EEI) of ≤0.20, complying with the strictest energy efficiency regulations, such as ErP. This motor not only offers low energy consumption but is also lock-resistant, ensuring reliable operation even under challenging working conditions.

With a maximum power consumption of only 20 W, this circulator pump significantly contributes to reducing energy consumption in heating systems, making it a cost-effective and eco-friendly option for any installation.

High-quality materials and durability:
The pump housing is made of gray cast iron, providing exceptional strength and durability, even in demanding working conditions. The impeller, made of PP-GF40, ensures high wear resistance, while the stainless steel shaft and metal-impregnated carbon bearings guarantee a long lifespan and smooth operation. These materials have been specifically selected to ensure that the pump can handle temperatures of up to 95 °C, making it suitable for most heating and air conditioning systems.

Ease of installation and maintenance:
The Wilo Yonos PICO1.0 25/1-4 is designed for easy installation, with 1½ inch threaded connections on both the inlet and outlet, allowing for quick and simple integration into existing systems. Additionally, its compact design with an installation length of 180 mm makes it easy to install in tight spaces.

Thanks to its integrated motor protection and purge function, maintenance of this pump is minimal, reducing long-term operating costs and improving system reliability. The IPX4D protection ensures that the pump is protected against water splashes, making it suitable for use in damp environments or in installations where exposure to liquids is common.

Ideal applications:
The Wilo Yonos PICO1.0 is suitable for a wide variety of applications, including radiator heating and underfloor heating systems, as well as for air conditioning in residential and commercial environments. Its high energy efficiency and ability to adapt to changing installation demands make it ideal for enhancing the performance and reliability of any modern heating system.

In summary, the Wilo Yonos PICO1.0 25/1-4 circulator pump is a high-efficiency solution, featuring advanced characteristics such as electronic control, LED indicator, and purge and unlocking functions, all designed to provide optimal operation in heating and air conditioning systems.
