Special Ceramic Solutions from Rauschert: Peter Schramm Contributes Expertise in Containment Shells

Rauschert in Pressig/DE, a specialist in Technical Ceramics and industrial technology, can count on the expertise of Peter Schramm in the field of special solutions. The proven expert in high-performance ceramics has been employed as a consultant by the Upper Franconian technology company since July 2020, to push the expansion of the product range with ceramic high-tech components such as containment shells for pump construction. In the fall of 2021, the first customer has received containment shells for magnetically coupled centrifugal pumps from Rauschert.

Peter Schramm, originally a trained toolmaker and mechanical engineering technician, has acquired a wealth of experience in ceramic manufacturing as well as in sales during his professional career. From setting up production at Hutschenreuther Technical Ceramics from 1986, through activities in their production and work preparation, his path led him to technical sales at TeCe Technical Ceramics in Selb. From 1999 to 2018, Peter Schramm worked as a project manager in the high-performance ceramics sector of FRIATEC, which was acquired by Kyocera Fineceramics in 2019. During this time, he oversaw the expansion of the product line of ceramic containment shells for magnetically coupled centrifugal pumps, which find their application primarily in the chemical industry. Furthermore, ceramic plungers and sensor elements have since been among his specialties

“Winning Peter Schramm for Rauschert was a great bonus for us,” reported Stefan Pfadenhauer, Department Manager Special Solutions at Rauschert in Pressig. “Especially regarding the development speed and product quality of customized, ceramic special solutions, his know-how means a great support.” For example, the adept Rauschert ceramics manufacturing department succeeded in developing its own containment shells made of zirconium oxide within a year.

Due to its antimagnetic nature, this material prevents the generation of performance-reducing eddy currents. In conjunction with the magnetic coupling, the drive is completely covered, ensuring no leakage of environmentally harmful, corrosive or toxic liquids. The high corrosion resistance of Rauschert zirconium oxide to most acids and alkalis also contributes to this.

Ceramic containment shells from Rauschert are also characterized by their thermal shock resistance and high mechanical strength. Test pressures of over 55 bar can be achieved without any problems. The wall thickness in the cylindrical area has so far been 1,5–2,9 mm depending on the inner diameter. This allows the gap of the magnetic coupling to be minimized, thus increasing the efficiency of the drive as far as possible. Rauschert is also working on alternative materials for improved pressure resistance of the containment shells.

As a pioneer for innovative technical solutions, the family-owned company Rauschert has been active in the business fields of technical ceramics, plastic moulded parts and industrial technology for more than 120 years. The range of services covers all stages of product development (material development, tool design and construction, prototype production, series production, module assembly) from the initial concept to series production, as well as the construction of customised production machinery and automation technology. This range is based on the expertise of approx. 1200 employees working for Rauschert in 16 countries.

Rauschert is represented as exhibitor at ACHEMA 2022: Hall / Booth 12.0 E42.
