Circulation Pump WILO YONOS MAXO 40/0.5-12 PN6/10 — 2120647

The WILO YONOS MAXO 40/0.5-12 PN6/10 is a compact circulation pump engineered for heating and hot-water systems. Designed with a 40 mm flange connection and a hydraulic performance range suitable for typical domestic and light commercial applications, this circulator supports reliable fluid movement in closed-loop HVAC and boiler circuits. The pump combines compact dimensions with features intended to optimize operational efficiency and maintain steady circulation under varying hydraulic conditions.

Advantages

The pump delivers stable hydraulic performance across a wide operating range, enabling consistent heat distribution and reduced temperature fluctuations. Its energy-efficient motor and hydraulic design reduce electrical consumption compared with older generation circulators. Built for PN6/10 pressure classes, the unit offers compatibility with common system pressures in residential and small commercial installations. The compact construction and standardized flange connection simplify installation and replacement in existing pump stations.

Suitable for

• Central heating circulation in single-family homes and apartment buildings
• Domestic hot-water recirculation
• Boiler system circulation and secondary loop pumping
• Light commercial HVAC systems with moderate flow and head requirements

Key specifications

• Flange diameter: 40 mm
• Hydraulic performance range: approximately 0.5 to 12 (head/flow range as specified by manufacturer)
• Designed for PN6/10 system pressure ratings
• Axial and hydraulic dimensions suitable for standard pump stations and retrofit applications
• Compact footprint for tight installation spaces

How to use

Install the pump in a closed heating or hot-water circulation circuit following local regulations and manufacturer installation instructions. Ensure correct flange alignment, appropriate sealing between connections, and that the system is filled and vented before operation. Connect electrical supply in accordance with the pump’s wiring specifications and applicable electrical codes. Adjust system balancing and control settings to match the hydraulic performance range of the pump for optimal circulation and energy use. Periodic inspection of connections, seals and motor function is recommended as part of routine system maintenance.

Usage recommendations

Select this circulation pump when replacing an existing 40 mm flange unit or when designing systems that require moderate head and flow capability within PN6/10 pressure classes. Verify compatibility with system controls and perform professional hydraulic balancing to maximize energy efficiency and maintain stable system temperatures.
