Wilo-Rexa UNI
For the sewage disposal of small commercially used buildings.
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. The low weight, the capacitor integrated in the single-phase AC motor and the fixings integrated in the flange provide easy installation. Direct access to the most important components makes maintenance very easy. Due to double seals 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.
