Intelligent sealing solutions for higher efficiency
The Parker Seal Group at HMI 2011
- "Smart Sealing Technology" showcased on stand 20 in hall B20
- In focus: fluid power, process engineering and renewable energies
- Featured again: the popular Parker-Prädifa Tech.Forum
The 2011 Hanover Fair (HMI) is billed as "Smart Efficiency". In line with the HMI motto the Parker Seal Group will be showcasing its products and solutions under the central theme of "Smart Sealing Technology - Intelligent sealing solutions for higher efficiency."
The spotlight will be on advanced "intelligent" sealing solutions in the fields of fluid power, process engineering and renewable energies. The advantages of the solutions range from bringing higher efficiency, safety and durability to various technical systems through to satisfying the most stringent hygienic demands in critical food processing and life science applications. In addition, the Parker Seal Group will present its new "Adhesives and Sealants" product range of modern, economical and "clean" solutions for a multitude of tasks in the field of maintenance, repair and operations (MRO). The Parker-Prädifa Tech.Forum, the popular platform for developers, designers, buyers and others with a keen interest in technology, will again put visitors in direct touch with sealing technology through "live" demonstrations of test rigs from the Parker-Prädifa physical lab, the use of computer simulation in seal development or the presentation of the wide range of materials and their specific characteristics and typical uses by the leading specialist in this field.
Friction optimisation continues to be one of the central keys to higher efficiency in the field of fluid power applications. Parker-Prädifa shows how the efficiency of hydraulic systems can be significantly enhanced by means of new, friction-optimised sealing materials and geometries.
Efficiency is also a result of factors like long service life and high operating reliability. They can be achieved, for instance, by reducing dirt ingress by means of the newly developed AV wiper. The wiper back with a large, externally protruding dirt shield protects against ingress of rain water. The integrated pressure relief function prevents the extrusion of the wiper from the groove in the event that pressure builds up between the seal and the wiper.
As simplified assembly leads to time and cost savings it is another way to increase efficiency. The showcased comprehensive range of composite sealing plates and washers, for example, facilitates quick and reliable sealing of flange connections. In addition, the versatile composite parts can be used to achieve reliable sealing concepts in diverse applications ranging from automotive engineering, air conditioning technology and general industrials through to the oil and gas sector.
Parker's newly developed hygienic sanitary gaskets feature a patent-pending design and are superbly suited to meet the exacting qualitative and technical demands of applications in hygienically critical process equipment and tube systems such as in the food processing and pharmaceutical industries. The nearly flush interface (± 0.2 mm) prevents entrapment of any media within a dead space that can lead to microbial growth and contamination. In addition, the flush design helps to prevent erosion of the elastomeric seal that could contaminate the process stream.
The sealing elements have been awarded international ASME Bio Processing Equipment (BPE) certification. Parker's hygienic sanitary gaskets demonstrated outstanding chemical resistance in extensive testing programmes, which particularly qualified this type of seal for food processing and pharmaceutical applications. Furthermore, each sealing element has a laser-engraved identification number which ensures complete traceability of the sealing materials from production through to installation.
Safe and efficient use of renewable energies makes special demands on sealing technology, particularly with respect to media resistance. An extensive range of sealing technology solutions designed to meet these needs is presented at the Parker HMI trade fair stand. Among other things, it encompasses special sealing materials and compounds which are suitable for use in wind farm applications involving high-frequency micro-oscillations. They also offer outstanding low-temperature properties and resistance against demanding media.
Newly developed special materials for solar-thermal systems are resistant to water- and oil-based heat transfer media plus aggressive additives and temperatures of up to +320°C. For photovoltaic systems, Parker presents UL-listed sealing materials that simplify the approval processes for system components. In addition to colour coding, they offer good low-temperature flexibility, ozone and weather resistance.
Production, maintenance and repair
The Parker Adhesives and Sealants product line offers a comprehensive range of solutions for various tasks in the field of industrial production, maintenance and repairs. Information on which solution is best suited for which task and instructions for usage have been compiled in a recently published useful guide in a clearly structured and easy to understand form. The guide is available on the trade fair stand.
The Parker-Prädifa Tech.Forum at this year's HMI again provides visitors with an opportunity to experience a number of highlights such as "live" demonstrations of testing facilities for various types of seals from the Parker Seal Group's physical lab. Concrete examples of seal development by means of computer simulation such as geometry optimisation, service life prediction, permeation investigations and much more are also showcased on location. In addition, the Tech.Forum provides insights into Parker's material development - from elastomer compounds, plastics and metals through to composite solutions featuring various materials.
The latest information straight from the source
Thanks to its long-standing in-house research and development at the highest level Parker-Prädifa is regarded as the leading materials specialist, offering the complete range of materials used in sealing technology. Naturally, the experts from research, development and application engineering are on hand at Hanover and prepared to discuss the aforementioned topics in greater depths in a personal dialogue. In addition, they are pleased to provide information regarding the latest challenges, trends and developments. Examples include ways in which material developers are responding to the anticipated increasing use of alternative lubricants or fully synthetic "new oils", how gas spring seals, which are an essential element of a multitude of commonly used equipment, are optimised in terms of critical permeation behaviour or how "alternative" piston rod coverings compared with traditional hard-chrome-plating affect the performance of hydraulic rod seals.
