Wilo-Yonos MAXO-Z 25/0.5-10 PN10 circulation pump 2175539

Circulation pump for DHW and heating systems

The Wilo-Yonos MAXO-Z 25/0,5-10 PN10 pump is an advanced solution for circulating domestic hot water and in heating systems. It is characterized by high energy efficiency (EEI 0.2) thanks to the use of a synchronous motor with ECM technology, which translates into lower operating costs.

The non-clogging design minimizes the risk of pump blockage and simplifies servicing.

Construction and application in installations

The pump is designed for operation in circulating circuits of domestic hot water in residential buildings, public utility buildings and industrial facilities. It will work well both in new installations and in the modernization of existing systems, especially where stabilization of the pressure difference or flow regulation is required. The body made of bronze (Rg 5) and the impeller made of polypropylene (PP-GF) ensure durability and corrosion resistance. Threaded connections 1 1/2 inch (BSPP) facilitate installation and integration with the existing hydraulic infrastructure. The maximum head is 10.92 m, and the maximum capacity is 9.522 m³/h – these parameters allow the pump to be adapted to various installation needs.

Functionality and benefits for the installer and user

• Electronic control: Allows precise adjustment of the pump operation to current demand, which translates into energy savings and user comfort. Possibility of choosing the operating characteristic: constant pressure difference, variable pressure difference or constant rotational speed (3 stages).
• High energy efficiency: EEI class 0.2 guarantees minimal power consumption (0.19 kW) while maintaining optimal efficiency – important both for the end user due to lower energy bills, and for the installer implementing energy-saving projects.
• Non-clogging design: Eliminates the risk of pump blockage by impurities, which reduces the frequency of failures and service costs.
• LED display: Facilitates pump configuration and monitoring of its operating status – quick reading of parameters facilitates diagnostics and allows for continuous optimization of the system.
• Built-in protective functions: Overheat and overload protection ensures reliable pump operation in various working conditions. Automatic unblocking after standstill facilitates starting after a longer period of inactivity and manual venting of the impeller chamber allows for quick removal of air from the system.
• Durable construction: Bronze body and polypropylene impeller ensure corrosion resistance and long device life – solid materials are a guarantee of reliability even in difficult operating conditions.
• Protection class IPX4D: Provides protection against splashing water, which allows the pump to be mounted in various locations inside the building.
• Connection length 180 mm: Allows easy installation in most standard hydraulic installations without the need to modify the existing infrastructure.
