Circulation pump WILO Yonos Para Z 25/7

The WILO Yonos Para Z 25/7 circulation pump is a modern, energy-efficient, and technologically advanced solution for heating, cooling, and water circulation systems in residential and commercial buildings. This model represents a new generation of electronically controlled pumps, delivering maximum performance with minimal energy consumption — starting from just 3 W, making it one of the most economical in its class.

The pump is equipped with a synchronous ECM-type motor, resistant to blocking currents and impurities, and features an integrated electronic power control unit that ensures smooth pressure adjustment according to system demands. Thanks to the wet-rotor technology, the pump operates almost silently and requires no maintenance throughout its lifetime.

Design and Control Features:

▪️ Electronic control with a rotary knob on the front panel for easy mode selection.
▪️ Automatic Δp-v mode (variable pressure difference) — the pump adjusts automatically to system conditions.
▪️ Option to select fixed speeds I, II, III for flexible operation.
▪️ Control modes for radiator and underfloor heating, optimizing flow and pressure.
▪️ Ventilation function for removing air from the system and preventing air locks.
▪️ Quick electrical connection via the Wilo-Connector for simplified installation.
▪️ Solid particle filter and motor protection from dirt for extended service life.
▪️ Durable housing with threaded connection, resistant to corrosion and pressure fluctuations.

Energy Efficiency and Standards Compliance:

The pump fully complies with the ErP (Energy-related Products) Directive, ensuring high energy efficiency and reduced operating costs. The ECM technology enables energy savings of up to 80% compared to standard circulation pumps.

Advantages of WILO Yonos Para Z 25/7:

▪️ Minimal energy consumption — from 3 W.
▪️ Suitable for all standard heating, cooling, and circulation systems.
▪️ Reliable and durable synchronous motor with anti-blocking protection.
▪️ Smooth power regulation and automatic load adaptation.
▪️ Easy operation, installation, and maintenance.
▪️ Silent operation thanks to the wet rotor.
▪️ Compatibility with various automatic control systems.
▪️ Manufactured in accordance with European quality and environmental standards.

Applications:

▪️ Water-based heating systems (radiator, underfloor, or combined).
▪️ Air conditioning and cooling systems.
▪️ Industrial installations with controlled liquid circulation.
▪️ Private homes, apartment buildings, and small commercial facilities.

The WILO Yonos Para Z 25/7 combines high energy efficiency, intelligent control, durability, and reliability. It is ideal both for retrofitting existing systems and for new energy-efficient installations, where stability, quiet operation, and minimal running costs are essential.
