OUR IN-HOUSE TEST PLANT AND LAB In order to ensure the high quality and long service life of our agitators, we have set up an in-house plant for testing our agitators. At the end of the manufacturing process, all of our agitators undergo a specific test procedure with a final test run. Here, we can test agitators with a shaft length of up to twelve meters. When designing our agitators, we use fluid mechanics simulations in our in-house laboratory. All Geppert mixing systems are delivered with O&M Manual and worldwide technical service.

Geppert Ruhrtechnik GmbH has been a certified manufacturer of explosion-proof agitator drives since 2003. This made us one of the first companies to develop and produce ATEX-compliant agitators. Our agitators are certified to ATEX Directive 2014/34/EU (formerly Directive 94/9/EC) in gas or dust explosion-proof designs. In addition, the majority of agitator styles have type test certificates for explosive zone 0, and can be used in applications in which an explosive atmosphere, arising from a mixture of air with flammable substances in the form of gas, vapor, or mist, is present. We offer ATEX-compliant controls for our explosion-proof design agitators. Talk to us and make use of our many years of experience on the topic of explosion protection. We will be happy to assist you! Our services in the field of explosion proof agitators

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.
