Wilo-Yonos MAXO 40/0.5-16

Finding the right pump for a commercial setup can be a challenge. A proper solution must be powerful, smart, reliable, and not drive up energy costs. The Wilo-Yonos MAXO excels in this role. It is the dependable workhorse for your heating, air-conditioning, or industrial system, expertly designed to make operations more efficient.

The Perfect Balance of Power and Intelligence

When managing a large-scale system, you need equipment that works reliably. The Wilo-Yonos MAXO is one of the smartest commercial circulators on the market, engineered by the experts at Wilo for set-and-forget reliability. Its glandless design means low maintenance, while its intelligent EC motor automatically adjusts to the system's needs, saving energy and lowering costs. Whether running hot-water heating with our commercial boilers, an air-conditioning system, a closed cooling circuit, or an industrial circulation setup, this pump is designed to be the heart of your operation.

Total Control at Your Fingertips

The Yonos MAXO’s true strength is its flexibility. It offers multiple operating modes to match your requirements. For steady pressure, the Δp-c (constant differential pressure) mode is ideal. For systems with changing demands, the Δp-v (variable differential pressure) mode intelligently adapts. You can also select one of three manual speed stages for straightforward jobs.

Control is simplified by the intuitive LED display, which shows the delivery head, speed stage, and any fault codes, removing guesswork from diagnostics. For seamless integration, a collective fault signal (a potential-free NC contact) communicates with your wider building management system. At National Pumps and Boilers, we recommend this pump for its blend of advanced features and simple operation.

Built for the Real World

Wilo understands commercial demands. The Yonos MAXO includes automatic functions like a soft start to reduce electrical stress and integrated motor protection to guard against power issues. Installation is also simple. The pump body has a wrench attachment point, and the Wilo-Connector allows for a quick, tool-free electrical hook-up. This balance of smart technology, robust protection, and user-friendly design makes it a professional favourite.
