Wilo-Stratos PICO-Z 25/0.5-6 threaded circulation pump. 4255434

Circulation pump for efficient heating and air conditioning systems

The Wilo-Stratos PICO-Z 25/0,5-6 circulation pump is an advanced solution for modern heating and air conditioning systems. Designed for high energy efficiency, reliability and ease of use, it is ideal for both new installations and modernization of existing ones. Equipped with a synchronous motor with ECM technology, it allows for significant reduction of operating costs compared to traditional, unregulated pumps. Its construction, based on a stainless steel housing and a PP-GF material impeller, guarantees long life and corrosion resistance.

Functionality and user comfort

The Wilo-Stratos PICO-Z pump offers a wide range of adjustment options tailored to different types of installations. Thanks to the built-in controller, you can choose the optimal operating mode - from constant rotational speed, through variable pressure difference (Δp-c), to automatic adjustment of performance to system needs (Wilo-Dynamic Adapt plus). A clear LCD display makes configuration and monitoring of operating parameters easier. In addition, the pump has functions such as automatic venting of the impeller chamber, key lock and dry-running detection, which increases safety and reliability. A five-year warranty demonstrates the high quality of the product and the manufacturer's confidence in its durability.

Design and application

The pump has been designed for easy installation and maintenance. Threaded connections (G 1½ inch on both the suction and discharge sides) ensure a tight connection to the installation. Compact dimensions (built-in length 180 mm) allow installation in limited space. The device is intended for circulating water in heating installations (temperature from 2°C to 95°C) and air conditioning installations (ambient temperature from -10°C to 40°C). The maximum pump capacity is 3.748 m³/h, and the maximum head is 6.411 m. Thanks to the insulation class F and protection degree IPX4D, the pump is resistant to harsh environmental conditions. The rated current of the pump is 0.44 A at a voltage of 230 V and a frequency of 50/60 Hz.
