Rubber mixers - Import export

For over 50 years, Geppert Ruhrtechnik has stood for quality and reliability in agitator construction. We develop, manufacture, and distribute innovative agitators for all applications in the materials processing industries, such as the chemical, pharmaceutical, biotechnology, and food industries, as well as in water and wastewater treatment. Our many years of experience make us the perfect partner for both standard and special applications. When selecting and designing our agitators, we draw on our many years of experience, internal databases, and state-of-the-art tools (such as FEM, Finite Element Method, and CFD, Computational Fluid Dynamics), as well as our own fluid mechanical laboratories. This means we always provide you with the optimal solution. In addition to our agitators, we manufacture suitable containers and stands for stand-alone, wall mounted, and mobile designs. We can implement these in your plants, taking into account any its specific requirements.

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 Ruhrtechnik 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. In addition, our agitators are used in broad solar cell production areas.

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.

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.

Mixing technology is particularly wide-ranging in the food and drinks industry. From simple suspension and homogenization tasks in storage or transport containers, right through to complex reduction tasks, during which mixtures can be exposed to only the lowest of shear forces – you will find it all in the food and beverages industry. High food sensitivity and the multitude of fields of application for agitators require close process coordination with the customer, in order to design, construct, and finish the agitators in the optimal manner with the widest variety of mixing elements. In addition to its popular standard mixers, Geppert also has special stirring elements within its portfolio, capable of being extremely gentle on the product while remaining highly efficient. All agitators have the relevant food approvals and can also be supplied with clean room drives and special sealing systems.

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.

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.

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.

Challenging, customer-specific mixing technology solutions can be numerically simulated as early as during the planning phase, and the results analyzed. This means increased design confidence, high-quality solutions and, as a result, reduced project durations and costs. Our experts from THINK Fluid Dynamix® are specialists in the application of numerical techniques such as flow simulation in real time and artificial intelligence methods for automated optimization. This enables processes, such as stirring and homogenization, to be analyzed more accurately under consideration of all applicable process parameters, and complex tasks to be processed far more efficiently. These methods set entirely new standards in terms of design reliability and efficiency. Allow us to contribute to your success!
