Wilo-ATMOS PICO 25/1-8 universal circulation pump 4232696

Universal circulation pump Wilo-Atmos PICO 25/1-8 – efficiency and reliability in every system

The Wilo-Atmos PICO 25/1-8 is a wet-rotor circulation pump with an EC motor, resistant to current blockage, designed for use in heating, air conditioning and cooling systems. Its design combines high energy efficiency, ease of use and reliable operation, making it an ideal solution for both professional installers and end users. The pump is particularly recommended for small heating and cooling systems, as well as for modernizing existing installations.

Functionality and versatility

Wilo-Atmos PICO offers a wide range of adjustment options tailored to different needs. Available operating modes include variable differential pressure (with three defined pump characteristics) and constant rotational speed (with three levels). The intuitive interface with a green button allows easy setting of the operating mode and pump power. Additionally, the pump has automatic functions, such as automatic restart after a failure and automatic unblocking of the impeller if it becomes blocked. An LED signal indicates the correct operation of the device or any problems.

Construction and materials

The pump is made of high-quality materials, guaranteeing its durability and corrosion resistance. The pump housing is made of gray cast iron, the impeller of glass fiber reinforced polypropylene (PP-GF40), and the shaft of stainless steel. This allows the pump to operate in a wide temperature range – from -10°C to 95°C for the medium and from -10°C to 40°C for the environment. The possibility of using glycol mixtures up to 50% expands the range of applications of the pump to cooling and solar systems. Threaded connections with a size of G 1½ facilitate installation in existing installations. The mounting length is 180 mm.

Advantages for installers and users

• Simple installation and operation: The intuitive interface with a single button makes configuration and pump control easy.
• Energy saving: The EC motor provides a high energy efficiency index (EEI ≤ 0.23), which translates into lower operating costs.
• Reliability: Fail-safe design and motor protection guarantee a long service life.
• Versatility: The ability to operate in different modes and with different media (water, glycol) makes the pump suitable for many applications.
• Automatic functions: Automatic restart and impeller unblocking minimize downtime and require less user intervention.
• Clear signaling: The LED indicates the operating status of the pump and any errors.
• Compact dimensions: Allow installation in tight spaces.
• High torque: Ensures smooth start-up of installations even with high flow resistance.

The Wilo-Atmos PICO 25/1-8 pump is an investment in the comfort, economy and reliability of a heating or air conditioning system.
