Powerful Solutions for Large-Scale Applications
There is a wide range of industries where, in addition to average-size and miniaturized equipment, large-scale systems are used that require components and sealing systems matching the size of the equipment.
The production of large seals for challenging applications is not simply a matter of scaling up know-how of traditional seal design. The reason is that XXL sizes not only pose particular handling challenges in the manufacturing process, but do so even earlier, in the design and testing stages.
As a specialist in engineered materials, engineering design and process technology Parker Prädifa offers an extensive portfolio of large-size seals and moldings made of polymers such as NBR, EPDM, FKM, PTFE and PEEK, as well as metal.
Polymer seals made from machinable materials
Using a new type of manufacturing technology, Parker Prädifa is able to produce polymer seals from machinable materials like PTFE and PEEK up to a diameter of 4.5 meters.
Thanks to innovative continuous vulcanization manufacturing technology there are practically no size limitations for elastomer seals.
Spring-energized metal C-rings can be produced in diameters of up to 7.6 m. Non-rotationally symmetric E-, O- and C-seals can be produced in lengths of up to 2.3m.
Whether small or large: In addition to the appropriate seal design, which Parker Prädifa develops for you using state-of-the-art simulation technology and virtual prototyping by means of Finite Element Analysis, the selection of the materials best suiting your application is crucial for XXL-size seals and moldings as well.
Besides metal seals, sealing solutions made of polymeric materials such as rubber, thermoplastic elastomers or other thermoplastic materials like TPU, PTFE and PEEK are commonly utilized.
There is a wide range of industries with large-scale systems requiring components and sealing systems in dimensions matching the size of the equipment. Diameters of several meters are not uncommon in many sectors such as manufacturing plant and equipment, buildings and pipelines, tunnel construction and mining, energy production, the oil and gas industry, high-tech medicine, aerospace and many others.
The demands to be met by XXL-size seals are as varied as the applications in which they may be used: media resistances, thermal and mechanical loads, environmental conditions, etc.
