Wilo-Rexa UNI

For the sewage disposal of small commercially used buildings.

Your advantages
Wilo-Rexa UNI

For the sewage disposal of small commercially used buildings.

The Wilo-Rexa UNI is suitable as an entry level model for smaller commercial buildings for sewage disposal (according to EN 12050-1). For this purpose, the pump can be used in a wide variety of applications, whether portable or in the pump chamber as a Wilo system solution. The new vortex hydraulics with corrosion-resistant composite and a smooth surface provide high reliability and allow the pump to be used universally with various fluids. Installation is very easy due to the low weight, the capacitor integrated in the single-phase motor and the fixings integrated in the flange. Maintenance is very easy thanks to direct access to the most important components. Due to double gaskets and the large sealing chamber, maintenance intervals can be increased. Wilo-Rexa UNI can be controlled via Wilo-Control switchgears and integrated into existing building management systems. With the Wilo-Rexa UNI, Wilo again proves its innovative leadership and underscores its system expertise by integrating single pumps, pump chambers and controls into higher-level systems.


Your advantages

  • Excellent reliability due to corrosion-free hydraulics for universal application and various fluids
  • Easy installation thanks to its light weight, integrated capacitor at the single-phase motor and flange with integrated fixation
  • Optimum efficiency and operational safety thanks to its vortex hydraulics and smooth surfaces
  • Quick maintenance facilitated by direct access to the sealing chamber and pump housing
  • Long maintenance interval thanks to its double seal and a high volume sealing chamber
