Wilo-Stratos PICO 25/0,5-8 circulation pump, 5-year warranty 4244397

Universal circulation pump for heating and air conditioning systems

The Wilo-Stratos PICO 25/0,5-8 circulation pump is an advanced solution for central heating and air conditioning installations. It is characterized by high energy efficiency, reliability and ease of use. It is ideal for both new and modernized systems, especially those equipped with thermostatic valves. Thanks to the use of a synchronous motor with ECM technology, the pump provides significant energy savings – up to 90% compared to traditional fixed-speed pumps. Importantly, the product is covered by a 5-year manufacturer's warranty, which confirms its high quality and durability.

Design and functionality for professionals and users

The Wilo-Stratos PICO has been designed for easy installation and intuitive operation. Compact dimensions (depth 112 mm, width 81 mm) make installation easier even in tight spaces. It is equipped with ISO 228-1 threaded connections with a diameter of 1 1/2 inches (40 mm), which ensures compatibility with most standard installations. The pump body is made of cast iron GG 20 (GJL-200), which guarantees strength and corrosion resistance, and the impeller made of polypropylene (PP-GF) ensures efficient medium flow. The maximum working pressure is 10 bar, and the operating temperature reaches up to 110°C.

The pump has a built-in motor speed controller, allowing you to adjust the performance to the current needs of the system. There are two control modes available: constant differential pressure (dp-c) and variable differential pressure (dp-v). The Dynamic Adapt function automatically optimizes the pump's operating parameters within a few minutes, ensuring maximum energy efficiency. In addition, the pump has integrated motor protection against overload and rotor blocking, as well as automatic venting of the rotor chamber. The LCD display shows the current power consumption and electricity consumption, allowing you to monitor the pump's operation and optimize operating costs.
