Wilo-Padus UNI
The flexible drainage pump for a diverse range of fluids.
The flexible drainage pump for a diverse range of fluids.
The Wilo-Padus UNI is the ideal entry-level model for wastewater transport in small commercial buildings. The pump can be used flexibly as a portable device or in a pump chamber. Hydraulics made from corrosion-free composite material provide high levels of reliability for universal use in the pumping of a diverse range of fluids. Installation is made very simple due to its low weight, integrated capacitor and threaded connection. A double mechanical seal and the large sealing chamber facilitate long maintenance intervals. Direct access to the most important components make maintenance work very convenient. By utilising Wilo-Control switchgears, the Wilo-Padus UNI can also be integrated into existing building management systems.
