## Long description

The WILO Yonos Maxo 40/0.5-8 is a high-efficiency circulation pump engineered for central heating and domestic hot-water recirculation systems. Designed with a flange connection and an adjustable head range, this single-pump model provides continuous fluid movement to maintain even heat distribution and stable system operation in residential and light-commercial installations.

Key specifications
Connection type: flange connection (DN 40)
Adjustable hydraulic head range: approximately 0.5–8 m
Application: circulation for heating and hot-water systems
Design: single-pump, continuous-duty construction
Flow control: adjustable to system resistance for optimized circulation
How to use
Install the pump in the return or delivery line of the heating circuit according to piping and flow direction markings. Ensure correct flange alignment, tighten bolted connections to the recommended torque, and follow local regulations for electrical connection by a qualified electrician. Adjust the pump head to the required setting based on system design and measured pressure/flow characteristics. After installation, purge air from the system and perform functional checks to verify stable flow, correct direction, and absence of leaks.
Usage recommendations
For energy-efficient operation, set the pump to the lowest head that meets system performance requirements and use automatic control strategies where available. Regularly check for air in the circuit and appropriate system water quality to prevent cavitation and corrosion. Service intervals should follow manufacturer guidance and local regulations; when replacing an existing unit, compare hydraulic curves and connection dimensions to ensure compatibility.
