Wilo-Padus UNI

The flexible drainage pump for a diverse range of fluids.

Your advantages
Wilo-Padus UNI

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 as a portable device or in a pump chamber for a diverse range of fluids. The hydraulics with corrosion-free composite and its smooth surface offers high reliability and makes the pump universal for use in diverse fluids. The installation of the pump is significantly easier due to the low weight, the integration of its capacitor in the single-phase motor and the threaded connection. Especially the maintenance is comfortable due to the direct access to the main components. The service intervals are long thanks to the double mechanical seal and the large sealing chamber. The Wilo-Padus UNI can be combined with the Wilo-Control and can be integrated into building management systems.


Your advantages

  • Exceptional reliability owing to corrosion-free hydraulics for universal applications and various fluids
  • Low weight, integrated capacitor at the AC motor and threaded connection allows for easy installation
  • Quick maintenance facilitated by direct access to the sealing chamber and pump housing
  • Long maintenance intervals resulting from a double mechanical seal and large volume sealing chamber
  • The integrated strainer ensures no clogging
