Lifting units and sewage pumps for every field of application.

It is not possible everywhere to simply dispose of sewage with a free gravitational flow into the sewers. Wilo lifting units or special sewage pumps provide reliable assistance in these cases.

Design
Sewage lifting unit with 2 integrated pumps

 

Application
Sewage lifting unit for drainage of residential housing and commercial buildings (e.g. restaurants, department stores, etc.). Raw sewage that cannot be piped to the sewer system through the use of natural inclines and sewage from toilet systems below the backflow level are to be piped to the public sewer system by means of an automatic lifting unit in accordance with DIN EN 12056/DIN 1986-100. Sewage containing mineral oils or explosive admixtures must be guided through oil precipitators and/or petrol precipitators; those containing fatty substances must go through grease traps and those with sand through sand catchers. In cases where the flow to the lifting unit must not be interrupted during normal operation, one lifting unit must be equipped with a second pumping unit that has the same performance capacity and switches on automatically when needed (DIN EN 12050-1 A1).
