We are experts when it comes to generating, storing and transporting power and energy in the most diverse fields and applications of industrial technology. These include industrial engines and transmissions, pumps, cylinder, valves and actuators, braking systems, axles, wheel hubs and tire pressure monitoring systems. It's all about pressure, temperature and media resistant, efficient, reliable and durable Sealing solutions and accumulators. Both standard and special custom solutions that meet all requirements. Everything from a single source: Sealing Technologies.
Pumps transport liquids. According to their multifunctional principle, they are divided into two basic categories: positive displacement pumps, which include rotor, vacuum, diaphragm, piston and plumber pumps, and axial, radial and diagonal centrifugal pumps. The latter are often referred to as flow pumps.
Sealingtechnologies seals are market leading for all these pump types. We provide pump manufacturers with state-of-the-art Simmerrings® for a wide range of pressures and temperatures, as well as homogeneous, fabric and fiber reinforced diaphragms, media resistant O-rings, flat and plate seals, usit rings and a wide range of custom precision molded parts.
The basis for this is formed by sealing materials developed and manufactured in-house. In terms of pressure, temperature and media resistance, durability and efficiency, they meet the high demands and economic expectations of pump manufacturers.
Valves and actuators control the flow or pressure of fluids in a system. Depending on the industry and intended use, their range extends from water to corrosive chemicals and radioactive substances. The safety and stability of the entire process always depend on the reliability of the sealing system.
Sealingtechnologies offers a unique range of high quality sealing solutions for valves and actuators, including valve seats, diaphragms, solenoid armatures, O-rings and other specialty seals and precision molded parts. In addition to the seal design, high resistance to a wide range of aggressive media is particularly important when handling liquids. We offer the ideal material mixtures for every application, including high-quality materials such as FFKM, EPDM, PTFE and polyurethane.
Whether for pumps, motors, cylinders or valves, stationary or mobile hydraulic and pneumatic systems, Sealingtechnologies develops seals that are perfectly matched to the increasingly demanding application areas and often harsh environmental conditions in fluid technology in terms of materials and geometries.
The highest quality sealing solutions from the Freudenberg premium brand ensure that components function even more reliably, efficiently and for longer, even under extremely high temperature and pressure requirements and in contact with aggressive hydraulic media. For less demanding applications, we offer economical sealing solutions from the Dichtomatik brand in high industry standard quality. The right solution for every need. Everything from one source. The same applies to our extensive range of batteries.
Whether in mining, ships, agricultural machinery or construction equipment, whether mobile or stationary applications: Combustion engines are the pacesetter of industrial production. They have paved the way for progress and economic growth for generations. Large diesel engines must operate reliably and economically even under the most adverse operating conditions. At the same time, they must comply with increasingly stringent emission regulations. Wherever you look, diesel and petrol engines also power our daily and leisure activities: in scooters and cars, but also in lawnmowers and chainsaws.
Static and dynamic seals from Sealingtechnologies, starting with the original Simmerring®, ensure leak-free functional reliability at all times. Rarely visible, but indispensable. Our sealing technology helps wheels turn and me to interlock in almost all life situations: low-friction, low-emission, technically and economically efficient and at the same time environmentally friendly.
In the future, electric motors with several tens of thousands of revolutions per minute will increasingly be used to specify new cycle rates. This increases the demands on the driveline in terms of temperature and pressure load. These requirements can no longer be met with conventional seals and materials. Thanks to our innovative power that comes from our materials, technology and product expertise, our pipeline is already filled with a wealth of new sealing concepts and products for the electric drives of the future.
In dynamic power transmission, force and kinetic energy are directed where they are needed. Industrial gear units convert torque and speed so that systems can fulfill their function perfectly. Mechanical power transmission also takes place at many other points in technical systems, for example in bearings, couplings, shafts or brakes.
Such operationally relevant functions require reliable sealing solutions. Here, the uniquely wide range of Sealing Technologies meets even the highest requirements, special developments in the premium segment stand out, such as Modular Sealing Solutions (MSS) or highly wear-resistant FKM materials.
The task of this high-tech seal is to combine increased reliability and service life with efficiency. Reliable and efficient mechanical drive components enable pioneering developments in industry and agriculture, advances in infrastructure and transport and global megatrends, such as digitization.
To develop tailor-made solutions for transmissions, braking systems, axles, wheel hubs or tire pressure monitoring systems (CTI), not only the know-how of experienced, innovative engineers is needed, but also modern technical equipment. This includes the world's largest testing facility for Simmerrings®. Extensive test series make it possible to precisely determine the interaction of the seal, lubricant and rotating shaft, tailored to the application – for optimally matched, efficient tribological systems.
In addition to dynamic resistance and tightness testing, we also offer a wide range of other advanced engineering services. These include damage, shaft and bore analyses, installation studies, benchmark tests, finite element analysis and much more.
