INVENT made a major contribution by introducing hyperboloid agitation technology to the water and wastewater treatment market more than 25 years ago.

Product Information

The HYPERCLASSIC®-Mixer is the optimum mixer for all suspending and homogenization tasks required for water and wastewater treatment.

The rotation of the hyperboloid-shaped agitator body close to the bottom generates high-speed and turbulence at the bottom of the basin. This reliably prevents the settling of sludge particles.

Eight transport ribs generate a three-dimensional main flow with a high circulation rate. This ensures excellent, uniform mixing.

Because of the low speeds, the energy input is low in shear force. Sludge flocculation is thus subjected mechanically to minimal stress loads.

Low speed at the water surface reliably prevents aerosol formation and oxygen transfer.

Efficient design and the use of rugged materials minimize operating and maintenance costs.

    Applications of the INVENT HYPERCLASSIC®-Mixer


    With denitrification, it is crucial that the entire tank content is homogenized and that oxygen entry on the surface is avoided. The HYPERCLASSIC®-Mixer is suitable for this, which generates a bottom flow directed radially outwards via transport ribs optimized in terms of flow mechanics. The particles are transported upwards along the pool wall. At the water surface, the speed has reduced to such an extent that no oxygen is introduced.


    For the destabilization of the colloidal state, a high energy input and a long contact time between the flocculant and the colloid are required for the formation of micro flocs. The CYBERPITCH®-Mixer combines these aspects with its flow-optimized agitator blade shape and its design for high speeds.


    Crucial for the success of the development of Markoflocking is a gentle agitation with simultaneous complete circulation of the entire tank content and the flocculation aids within the dwell time.

    The HYPERCLASSIC®-Mixer has low shear forces due to its hyperboloidal agitator body shape and low speeds and at the same time ensures complete mixing of the container. This leads to frequent particle interactions, which enables maximum floc growth.


    When conditioning the water, chemicals are added, which should be distributed as quickly and homogeneously as possible in the tank.

    If high energy inputs are required, the CYBERPITCH®-Mixer is suitable due to its high speeds and its robust design made of high-quality stainless steel. The INVENT HYPERCLASSIC®-Mixer is used to adjust the pH value and water hardness when energy-efficient mixing of the tank contents is sufficient.


    The CYBERPITCH®-Mixer is suitable for quickly and efficiently stirring in the activated carbon and mixing it during the reaction time (adsorption) if a high local energy input is required. The HYPERCLASSIC®-Mixer is used for applications with low shear forces, as it ensures complete mixing that is much more gentle on the particles thanks to the lower speeds, a larger agitator diameter and the design of the agitator body close to the bottom.
