Wilo-Yonos MAXO 40/0,5-12 PN6/10 circulation pump 2120647

High-efficiency circulation pump for heating and air conditioning systems

The Wilo-Yonos MAXO 40/0,5-12 PN6/10 pump is an advanced solution for central heating, air conditioning and ventilation installations. It utilizes energy-saving ECM technology, offering stepless performance regulation and significant energy savings. It is a canned motor pump, which translates to quiet operation and minimal maintenance requirements. Thanks to its wide range of operating parameters, it is ideal for both new installations and the modernization of existing systems.

Design and application

The pump is designed for circulating water in closed heating, air conditioning and ventilation installations. Its design based on a synchronous motor with permanent magnets (ECM) ensures high energy efficiency – EEI class 0.2. Equipped with an integrated performance control system, it allows for precise adjustment to the current system needs, minimizing energy consumption. The pump body made of cast iron GG 25 (GJL-250) ensures durability and corrosion resistance, especially thanks to the cathodic dip coating (KTL). The impeller made of polypropylene (PP-GF) is resistant to the action of the heating medium.

Advantages and benefits

• High energy efficiency: EEI class 0.2 allows for significant reduction of operating costs compared to traditional pumps.
• Stepless regulation: Smooth adjustment of performance to system demand ensures optimal comfort and energy savings.
• Wide range of applications: Can be used in heating, air conditioning and ventilation installations with different characteristics.
• Durable construction: Cast iron body and KTL coating provide corrosion resistance and long pump life.
• Quiet operation: Direct coupling of the motor to the impeller eliminates noise associated with pump operation.
• Automatic venting: The impeller chamber is automatically vented, eliminating problems associated with the presence of air in the installation.
• Impeller unblocking function: Prevents the impeller from locking after a prolonged period of inactivity.
• Wide temperature range: The pump operates in an ambient temperature range of -20°C to +40°C and a medium temperature range of -20°C to +110°C.
• Simple installation: Mounting dimensions are compatible with standard circulation pumps, making it easy to replace older devices.

The Wilo-Yonos MAXO 40/0,5-12 PN6/10 pump is an investment in the comfort, savings and reliability of a heating or air conditioning system – both for professionals involved in installations and for end-users looking for effective solutions.
