Wilo-Yonos MAXO-Z 40/0.5-12 PN6/10 circulation pump 2175543

Circulation pump for heating and air conditioning systems

The Wilo-Yonos MAXO-Z 40/0.5-12 is a high-efficiency circulation pump with electronic control, designed for closed circuits in heating, air conditioning and ventilation systems. Its design and parameters make it ideal for both new installations and modernization of existing ones. Thanks to the use of an EC motor with automatic performance adjustment, the pump provides significant energy savings compared to traditional pumps.

Construction and application

The Wilo-Yonos MAXO-Z 40/0.5-12 is characterized by a housing made of bronze (Rg 5), which ensures high corrosion resistance and long life. The polypropylene (PP-GF) impeller is resistant to the action of the pumped medium. Flanged connections (DN 40) with a pressure class of PN 6/10 allow easy installation in various installation configurations. The pump is adapted to work in an ambient temperature from 0 to 40°C and medium from 0 to 80°C. It finds application in:

• Hot water heating installations
• Air conditioning systems
• Closed ventilation circuits
• Industrial circulation installations

Key features and benefits

• High energy efficiency: Energy efficiency class A and EEI index at 0.23 guarantee significant savings in electricity consumption. The EC motor automatically adjusts the performance to the current system needs, minimizing energy consumption.
• Durable construction: The bronze housing and polypropylene impeller provide corrosion resistance and long pump life. The cathodic coating additionally protects against corrosion in the event of condensation.
• Easy operation and installation: The terminal box located at the front of the device facilitates access during installation and maintenance. The possibility of mounting in various positions and the position-independent display increase installation flexibility.
• Precise regulation: The built-in motor speed controller allows precise adjustment of the pump performance to the system requirements, ensuring optimal operating conditions and user comfort.
• Expandability: The pump can be equipped with additional communication modules (Modbus, BACnet, CAN, LON), which enables integration with building automation systems and remote control.
• Performance: The maximum pump capacity is 24.83 m³/h at a head of up to 12.58 m, and the nominal flow rate (BEP) is 12.85 m³/h at a head of 79.23 kPa. The motor power consumption (P1) is 0.55 kW at a rated current of 2.4 A and a voltage of 230 V.
