Wilo-Yonos MAXO 65/0,5-9 PN6/10 circulation pump 2120653

Wilo-Yonos MAXO 65/0.5-9 Circulation Pump – an efficient solution for modern installations

The Wilo-Yonos MAXO 65/0.5-9 pump is an advanced device designed for circulating water in heating, air conditioning and cooling systems. It is characterized by high energy efficiency (EEI 0.2) and intelligent control, which translates into lower operating costs and greater user comfort. The pump design allows for direct mounting in place of older models without the need for additional modules.

Construction and application

The pump was designed with reliability and ease of use in mind. Made of cast iron GG 25 (GJL-250) with a polypropylene (PP-GF) impeller, it ensures durability even in harsh working conditions. Designed for use with installations with a nominal diameter of DN 65, it has flanged connections in accordance with EN 1092-2. A wide range of medium temperatures (-20°C to +110°C) and ambient temperatures (-20°C to +40°C) make it a universal solution for various applications – from domestic heating systems to industrial circulation installations.

Advantages and benefits

• High efficiency: Thanks to the EEI index of 0.2, the pump minimizes electricity consumption, which translates into financial savings. The motor power consumption is only 0.6 kW, and the minimum power consumption is 5W.
• Intelligent control: Stepless speed control allows for precise adjustment of the pump's performance to the current system needs, both in constant pressure (p-c) and variable pressure (p-v) mode.
• Reliability and safety: Integrated full motor protection and automatic venting of the impeller chamber ensure long-term and trouble-free operation of the device. The built-in fault indicator informs about any problems in the installation.
• Easy installation and operation: 1:1 dimensional interchangeability with older Wilo-Stratos pumps facilitates the modernization of existing installations. Simple operation using the red Wilo knob and a convenient plug with a pull-out protection further increase user comfort.
• Durability and corrosion protection: The pump body coated with a cataphoresis coating (KTL) protects against corrosion, even in the event of condensation.
• Automatic return to settings: After a power failure, the pump automatically returns to its previous parameters, eliminating the need for reconfiguration. The impeller unlocking function after a period of inactivity prevents it from locking and facilitates restarting the pump.
• LED display: The built-in LED display shows the current head and fault messages, making it easier to monitor the pump's operation.

The Wilo-Yonos MAXO 65/0.5-9 pump is an investment in the comfort, savings and reliability of a heating or air conditioning system.
