Macerator Gerios® 2-in-1 sewage disposal unit with high-performance cutting system

2

Basement extensions are a good way to create additional living space. Unused areas in the basement can be easily converted into appartments or hobby rooms using sewage lifting units. The Gerios® not only pumps wastewater from the toilet and urinal, but also wastewater from the bidet, washbasin and shower thanks to its versatile connection options. Furthermore, the installation of an additional toilet in rooms with a long distance to the main sewage pipe or sewer can be realized with the Gerios®. For installations below the backflow level, the system also serves to protect against backflow from the sewer and always remains ready for action.

Flexible application

The Gerios® made by Zehnder Pumpen in Germany covers both installation option within one device. Both the classic direct connec-tion to a free-standing toilet and the modern, invisible installation within an in-wall element using a wall-mounted toilet can be real-ised thanks to its compact dimensions. All the necessary parts for using the various connections are included in the scope of delivery.

The Gerios® in detail

Even though wet wipes and toiletries must not be disposed in a toi-let, experience has shown that this regulation is often disregarded on purpose or unintentionally. In order to ensure operational safety even in this exceptional situation, the Gerios® has a unique and extremely powerful cutting system.

Precise cuttingThe special construction of the cutting blade with 3 cutting edges and the cutting plate in combination with a cutting gap of less than 0,05 mm ensures reliable cutting of more solid materials and fibres. The design guarantees maximum comminution of solid materials with 1,200 cutting operations per second.

High-quality materialsThe high-performance cutting system is made of corrosion-resistant special steel 1.4112 with extreme hardness (67 HRC). The used ma-terials provide very high wear-resistance and guarantee correspond-ingly optimal cutting performance in the long-term.
