                  • Chemical & Petrochemical

                  • Variable and diverse

                    Mixing of substances and chemical reactions are closely interconnected. The way in which different reagents are mixed together can have a significant influence on product quality, product yield, or even on the resulting product itself.

                    Stirred reactors are used in the chemical industry for a range of applications. They can be used for reaction, extraction, distillation, crystallization, and other processes. Depending on the reactor process and operating mode (continuous, semi-batch, or batch operation), the agitators used can be subjected to varied demands.

                    In the petrochemical industry, emulsification, absorption, desalination, alkylation, or neutralization processes are commonly found; lubricating oils must be homogenized or sludge oils suspended.

                    For this wide variety of mixing tasks, Geppert offers tailor-made agitators to satisfy operational and customer requirements.

                    Fields of application

                    All stirring and mixing tasks in the chemical and petrochemical industry, for the production of:
                    basic chemicals, hydrofluoric acid chemicals, fine chemicals, specialty chemicals, plastic resins, plastic materials, adhesives, ethoxylation and hydrogenation, chlorination, and many more.

                    Materials

                    We have the ability to construct our agitators from conventional or special materials, in the surface quality desired. We use all available stainless steels, titanium or tantalum, as well as a wide range of plastic coatings. We select materials according to the process requirements and customer preferences.

                  • Paints & Coatings

                  • Dispersion and Homogenization

                    Paints and coatings play a significant role in our lives. Without them, life would be dull and even monotonous. But they don't just provide color. They perform a multitude of other tasks as well. For example, they protect objects or structures from corrosion and deterioration, thus contributing to the sustainable use of resources. Equally, special coatings can contribute to a reduction in flow resistance, or create a pearled finish that makes objects easier to clean and reduces contamination.

                    Paints and coatings generally consist of binders, fillers, pigments, solvents, resins, and perylene, as well as additives. These substances must be mixed together homogeneously during the production process. Various agitators are used to achieve this, for example dissolvers, depending on the process step and according to the boundary conditions.

                    Different agitators can be used for this task. Low-shear mixers in storage tanks ensure that the coating does not separate. Paints and coatings frequently require stirring even during transport to their point of use. Geppert offers optimized mixing concepts for this too.

                    Our product range extends from agitators for drums, roll containers and IBCs¹, through tripod agitators, right up to agitators with retractable stirring elements. Regardless of whether mixing is required in open or closed containers, or during storage or transport of paints and coatings – Geppert has the solution to suit your application.

                  • Pharma & Biotech

                  • Specialized and challenging

                    The pharmaceutical and biotech industry involves a wide range of mixing tasks, for which precision and consistence are of utmost importance.

                    Particles must be evenly suspended and homogenized in liquids for filling processes. In some cases, multiple processes, such as for example heat transfer, rapid mixing, or material transport, must take place simultaneously within one reactor. Specific requirements are often placed on the drives, if for example production is carried out under clean room conditions. The surface quality of the stirring elements must always meet the highest standards; they are therefore usually electropolished.

                    Our agitator solutions for the pharmaceutical and biotech industry are engineered and manufactured to customer-specific requirements. Selection of the agitator, as well as of the drive and sealing concepts, depends on the process and customer specifications. We will provide all the necessary design calculations, or simulate the mixing process.

                    Fields of application

                    All applications in the pharmaceutical and biotech industry, such as pharmaceuticals, enzymes, yeasts, proteins and amino acids, vitamins, cell cultures, substrate production, sterilization of fermentation media, aerobic and anaerobic fermentation, synthesis, cell disruption, product concentration and purification, crystallization, or hydrogenating applications.

                  • Water & Wastewater Treatment

                  • Multifaceted and challenging

                    In the treatment of drinking water, whether done conventionally or via seawater desalination, agitators are used for rapid mix, precipitation and flocculation processes. Precipitation and flocculation processes require low shear, slow-running agitators. For pH adjustments and rapid mixing faster running agitators that can blend reactor content in a flash are required.

                    Wastewater treatment also requires a multitude of application options for agitators. In anaerobic and anoxic tanks for nitrogen removal, slow-running agitators are used to suspend and homogenize activated sludge flocs. In aeration tanks, mixer/aerators can be used for efficient oxygenation and mixing.

                    Where waste water is purified, sludge is generated. This sludge is generally conditioned using polymers, dewatered, and then digested in anaerobic sludge digesters to generate biogas. Special agitators are required for both polymer introduction and for digested sludge mixing.

                    For water and wastewater treatment also, Geppert can offer a multitude of specially developed agitators. From energy-saving hyperboloid mixers for anaerobic and anoxic tanks, to hyperboloid mixing and aeration systems for aeration tanks, or digested sludge agitators with gas seal and explosion-proof drives. Geppert has the solution, experience, and supplies complete systems from a single source.

                    Fields of application

                    In addition to all the usual stainless steels, for the water sector we also offer agitators and shafts made from fiber-reinforced plastic. These are lightweight and corrosion-resistant.

                  • Paper & Pulp

                  • Reactive and complex

                    Despite the increasing level of digitalization, an ever-increasing demand for paper and pulp products can be observed. However, a shift is taking place from print paper qualities to packaging paper and cardboard.

                    The wide range of paper products requires a variety of production processes. These include mechanical and chemical processes which, depending on the form and variant, produce different pulp qualities. Stirring and mixing are essential unit processes in all types of paper and pulp production. Mixing tasks range from liquid/liquid or gas/solid/liquid mixtures, through mixing of complex liquids, and include mixing of chemically reactive components.

                    Improving and optimizing mixing processes in the paper and pulp industry can lead to end product improvements; such as increased strength, improved luster, or significant energy or chemical savings. Such process optimizations require precise analysis of the process conditions, a clear definition of the objective, and an understanding of not just process, but also fluid mechanics. Geppert offers a range of proven agitators for all applications in the paper and pulp industry, with which you can achieve such improvements and savings.

                  • Semiconductor Technology

                  • Progressive and innovative

                    In the manufacture of semiconductors, agitators are mainly used in conditioning of polishing and cutting suspensions, etchants and other auxiliary chemicals, cleaning solutions, or in chemicals recycling. Requirements placed on stirring systems are extremely demanding.

                    Almost always, clean room conditions prevail, meaning that drives and seals must be designed with no abrasion or leakage. Parts that come into contact with the medium, such as the shaft and stirring element, often have to be produced with metalfree surfaces due to the aggressiveness of the media and the purity requirements.

                    Also in this area, Geppert Rührtechnik can look back on a very successful history. All well-known chip manufacturers belong to our client base, as well as the manufacturers of the specialty chemicals used in this field.
