Wilo-Yonos MAXO-D Circulation Pump – Efficiency and Reliability in Every System

The Wilo-Yonos MAXO-D 32/0.5-7 PN6/10 circulation pump is an advanced solution for circulating water in heating, ventilation and air conditioning systems. Its construction, based on a synchronous motor with ECM technology, guarantees a high level of energy efficiency (EEI 0.23) and minimal power consumption – even 5W. This translates into real operating savings and a reduced environmental impact. The pump is designed to operate in a wide range of medium temperatures (-20 to +110°C) and ambient temperatures (-20 to +40°C), making it a versatile choice for various applications.

Construction and application – robustness and versatility

Wilo-Yonos MAXO-D is a twin pump, which means it can operate in main/reserve mode, increasing the reliability of the entire system. The pump body made of cast iron GG 25 (GJL-250) ensures durability and corrosion resistance, and the polypropylene (PP-GF) impeller guarantees efficient operation even with contaminated media. Flanged connections DN 32 (EN 1092-2) facilitate installation and integration with existing infrastructure. The pump is ideal for central heating installations, domestic hot water systems and industrial applications requiring precise flow control.

Functions and advantages – user comfort and ease of operation

The Wilo-Yonos MAXO-D pump offers a range of functions to facilitate its configuration and operation:

• Stepless performance control: Smooth adjustment to current system needs by selecting a p-c (constant pressure) or p-v (variable pressure) operating characteristic.
• Automatic venting: Eliminates the problem of air accumulating in the impeller chamber, ensuring stable pump operation.
• Integrated motor protection: Protects the motor from overload and short circuit, increasing its lifespan.
• Impeller unblocking function: Allows easy starting of the pump after a long period of inactivity.
• LED display: Intuitive display shows the current head and messages about any failures.
• WILO plug: Convenient plug with pull-out protection facilitates electrical connection.
• Automatic return to settings: After restoring the voltage, the pump automatically returns to previous operating parameters.
• Fault signaling: Built-in visual signaling and a collective fault signaling contact inform about problems with pump operation.

Additionally, the pump is fully compatible with standard circulation pumps, allowing replacement without the need to modify the installation. The KTL coating on the housing provides corrosion protection even in humid environments.
