Wilo-Atmos PICO 25/1-4 Universal Circulation Pump – Efficiency and Reliability in Every System

Wilo-Atmos PICO is a wet-rotor circulation pump designed for easy installation and operation. It is suitable for both new installations and as a replacement for older models. Its versatility will be appreciated by both professionals and end-users looking for an efficient solution for heating and air conditioning. The pump is characterized by high energy efficiency thanks to the use of an EC motor resistant to blocked current.

User Comfort and Advanced Features

Pump operation is intuitive thanks to the "green button" technology and a clear user interface. This allows easy setting of operating parameters tailored to the specifics of the installation. Wilo-Atmos PICO offers several operating modes: variable differential pressure (with three defined pump characteristics) and constant rotational speed (with three stages). Additionally, it has automatic functions, such as automatic restart after a power failure. LED signaling informs about the correct operation of the device and any malfunctions – a green diode indicates normal operation, and a flashing or glowing one indicates a problem.

Construction and Application

The Wilo-Atmos PICO 25/1-4 pump has a threaded connection Rp 1” and a mounting length of 180 mm, which facilitates its integration with existing installations. It is intended for use in heating, air conditioning and industrial circulation systems. Thanks to its high corrosion resistance and durability of components, it ensures reliable operation for a long time. The ECM motor used is characterized by low power consumption (from 4W to 20W) and high energy efficiency (EEI ≤ 0.20), which translates into lower operating costs. Thanks to the minimum inlet pressure of only 0.3 bar at a temperature of 95°C, the pump will work even in difficult installation conditions.
