Your advantages
Wilo-Stratos MAXO-Z

Superior intelligence, unparalleled quality.

The Wilo-Stratos MAXO-Z has specifically been developed for drinking water applications and combines the innovative characteristics of the Wilo-Stratos MAXO with a stainless steel housing. The durable and hygienic material sets it apart from other domestic hot water circulators on the market.



Your advantages

  • Intuitive operation by application-guided settings with the Setup Guide plus the combination of a new display and operating button using the Green Button Technology
  • Highest standard of drinking water hygiene and energy efficiency with the new, intelligent T-const. control function.
  • Optimum hygiene support thanks to the detection of thermal disinfection
  • Latest communication interfaces (e.g. Bluetooth) for connecting to mobile terminal devices and direct pump networking using Wilo Net for multiple pump control
  • Maximum convenience in electrical installation thanks to a clearly arranged and spacious terminal box and the optimised Wilo-Connector

Environmentally friendly features

  • Combination of optimised and innovative control modes provides maximum energy efficiency
  • Sustainable and carbon-neutral production and processes in our European factories
  • Full transparency of the pump's operating status via remote access to save resources compared to on-site assessments
