Wilo-Yonos MAXO 80/0,5-6 PN10 circulation pump 2120657

Circulation pump for highest efficiency for modern installations

The Wilo-Yonos MAXO 80/0.5-6 PN10 circulation pump is an advanced solution designed for efficient water circulation in heating, ventilation, air conditioning systems, and in closed cooling circuits. Equipped with an energy-saving ECM motor and electronic differential pressure control (Δp), it ensures a stable flow and minimizes energy consumption. The design with a flanged connection (DN 80) facilitates integration with existing infrastructure.

Construction and application

The pump is designed for a wide range of applications – from boiler rooms with condensing boilers and heat pumps, through nodes with plate heat exchangers, to mixing group distributors and cooling circuits. Thanks to the wide range of head (0.5-6 m) and maximum performance of 50.85 m³/h, it is a universal choice for both new installations and modernization of existing systems. PN10 execution ensures compatibility with popular armature standards. The ability to work with circulating water and water-glycol mixtures increases its flexibility.

Advantages and benefits

• Energy saving: The ECM motor and Δp control minimize power consumption – even down to 5W in minimum mode – which translates to lower operating costs. The energy efficiency index (EEI) at 0.2 confirms the high efficiency of the pump.
• Quiet operation: Smooth performance regulation eliminates flow noise and throttling, ensuring acoustic comfort.
• Stable flow: Electronic Δp control maintains a constant differential pressure regardless of the load on the installation, which guarantees uniform flow through heat exchangers and heating/cooling loops.
• Automatic functions: Built-in functions for venting the impeller chamber and automatic unblocking of the impeller after a period of inactivity minimize the risk of failure and downtime. Automatic return to settings after a power failure further increases reliability.
• Durability: The pump housing made of cast iron GG 25 (GJL-250) provides corrosion resistance, and the cathodic coating (KTL) additionally protects against external factors. The impeller made of polypropylene (PP-GF) is resistant to abrasion and chemical corrosion.
• Simple installation and operation: Dimensions allowing 1:1 replacement with older pump models facilitate installation modernization. Intuitive control via the Wilo control knob allows easy setting of operating parameters.
• Fault signaling: Standard built-in fault signaling informs about any problems in the pump operation.

The Wilo-Yonos MAXO 80/0.5-6 PN10 pump is an investment in the comfort, economy and reliability of a heating or air conditioning system – both for professionals involved in installation and for end-users who value effective solutions.
